Defect and Microstructure Analysis by Diffraction is focused on extracting information on the real structure of materials from their diffraction patterns. The primary features of a powder diffraction pattern are determined by the "idealized" periodic nature of the crystal structure. With the advent of computer automation the techniques for carrying out qualitative, quantitative and structure analysis based on the primary pattern features rapidly matured. In general, the deviations of a particular specimen, from the ideal or perfect crystal structure, cause diffraction peak profiles to broaden and sometimes to become asymmetric. Thus, information on the real structure or microstructure of a specimen can be obtained from a careful study of the diffraction line profiles. The evolving techniques for microstructure analysis from diffraction patterns such as micro-strain, crystallite size, macro-strain and preferred orientation analysis require an ever more detailed understanding of the effects of crystallographic mistakes on peak assymmetry and the effect of the distribution of small crystallites on the tails of diffraction peaks. This book provides a comprehensive analysis of the fundamental theory and techniques for microstructure analysis from diffraction patterns and summarizes the current state of the art. This complete survey lays the foundation for the next and last major development in this field: the extraction of the full information in a powder pattern by the simulation of the full experimental pattern. The goal of this branch of science is to extract all of the information locked in the powder diffraction pattern including: the types and densities of stacking faults, the strain field produced by each, the anisotropic crystallite size and orientation, along with the size and strain distributions of each phase in a specimen. This book provides a complete summary of the developments of the twentieth century and points the way.

Bloodied bodies littered the floor of the warehouse and the sands of the beach along the quiet shore of Lake Erie. The Shadows' invasion stopped and their human followers defeated. Their portal to Earth closed. But for how long? And what about the other worlds? Even now Duat was under attack. Duat, the home of Ra.Arthur took a deep breath. He was exhausted. This gift, or curse, this power of the Blocker, awakened within him by some unknown entity to fight these monsters, held a price. Gone was the life he had known, taken from him as he was thrown into a war that few on his world knew existed. Forcing him to become a soldier, a warrior. Thrusting him into a fight where he had to kill these things before they could kill him. It had changed him.Feeling the weight of the sword in his hand he glanced down.  Excalibur, the sword created by Merlin for Arthur Pendragon, King Arthur. Now his. His alone to use. He had. He had never killed a man before.Turning his head he focused on those that had fought at his side. Warriors from surrounding dimensions. Heroes of myth and legend standing with him in this fight to save his world. Was it now time for him to help defend theirs?A young woman took his hand. Kathleen, the beautiful daughter of The Emrys. She believed in him. Believed as did the others he might be their salvation. The one with the power to end the Shadow War. The legendary First Dragon. But was he?

The quiet war grows louder as a new evil emerges from the shadows. Stronger, darker, more deadly than anything the warriors of the Alliance have faced in their centuries old conflict with the Shadows. Will it take an unholy allience to deal with this new threat? Can Arthur and the Oathsworn of the Dragon stop what is comming? What will be the cost?

This book represents the proceedings of the second inter­ disciplinary conference on materials characterization held from July 30 through August 3, 1984 at the New York State College of Ceramics at Alfred University. The conference was the 20th in the University Series on Ceramic Science, instituted in 1964 by Alfred University, the University of California at Berkeley, North Carolina State University and Notre Dame University. Volume I of the proceedings of the first conference using this interdisciplinary approach to materials characterization was published as "Advances in Materials Characterization", edited by D. R. Rossington, R. A. Condrate and R. L. Snyder, and was listed as volume 15 of the Materials Science Research series of Plenum Press (New York, 1983). The purpose of bringing together scientists from a wide range of disciplines to present and discuss the latest developments in their fields is to promote cross fertilization. The first conference of this type and its resulting volume of proceedings stimulated a significant dialogue between disciplines concerning the characterization of materials, therefore indicating a need for a continuing series of such conferences. Characterization lies at the core of materials science.

As warriors from two different worlds pursue separate quests to right the wrongs of injustice in their realms, fate sets them on a shared path to thwart an even greater danger. Crown Prince Henry of Cent is tasked with an unenviable assignment: collect taxes on behalf of his father, the king. But as he arrives in the village of Eldon, he discovers that all is not as it seems with whispers of daemons stalking the land. With the villagers living in fear, and children going missing, the prince and his men must venture into the Dark Forest on the other side of the Valley of Storms to seek answers. Meanwhile, Special Operative Hal Bennet is also on a deadly assignment in an abandoned village located in the deserts of Afghanistan. Sent to capture a ruthless arms dealer, Hal's mission takes a turn for the worse leaving the soldier injured, traumatized, and in need of recovery.Seeking solace in an isolated cabin in northern Maine, Hal questions what that future holds. But when there is a mysterious knock at his cabin's door, the answer that he receives is beyond his wildest imaginings.

Seeking solace in a remote mountain cabin in northern Maine, haunted by the recent loss of a comrade during an operation in Afghanistan, Special Operations Operative, Hal Bennet questions his sanity when awakened in the middle of the night by what appeared to be a medieval knight.No sooner has the man calling himself Crown Prince Henry Lackland introduced himself to a confused Hal, than the knight is whisked away once again during a strange and terrible storm. The sudden and unearthly disappearance leaves the Special Forces Operative questioning his own sanity. But Henry left proof of their encounter—his chainmail and sword.Haunted for a year by the strange encounter, Hal is driven to return to the same mountain cabin, hoping to find answers to the questions that constantly circle in his mind. How did this happen? Why did it happen to him? And where did Henry go? Uncertain of what lies ahead, he ventures forth into the same terrible storm and similarly vanishes.Upon waking on the isle of Glenlock, Hal finds himself thrust into a world of kingdoms populated by civilizations from Earth's past. A world where malevolent forces are lurking as bands of strange-looking men, deformed daemons bent on destruction and abduction, threaten the land.Can Hal overcome his past demons to rise to the fight ahead, or is Glenlock destined to fall into darkness?

Forced to flee her village as a child, Branwen seeks shelter in a forest long thought to be haunted. Found and cared for by the woods' mysterious guardian and her magnificent she-wolf, Branwen is raised in safety until the day she comes upon a young boy and his tutor. An encounter that will awaken a destiny that will ignite legends to be. Hers and one other. Drawn into a world of power and magic, Branwen soon discovers that enlightenment offers both wonder and danger. A danger so great it could cost the lives of those she cares most about. Protecting herself and those that are dear to her, Branwen must confront her ultimate destiny. A destiny where she will be forced to become something else. Someone else. Branwen is the story of King Arthur and the sword in the stone. Narated by the young girl who witnessed it all.

Transported by a strange and terrible storm from a mountaintop in Maine to the island of Glenlock on a world called Tera, Special Operations Operative Hal Bennet joins forces with knights of Cent to defend the land from Daemons. Strange-looking men who have ravaged Glenlock, burning villages, killing the innocent, and taking their youngest children. Why did they come to Glenlock, and what did they want with the children remains a mystery. The Daemons were not alone. With them were two men wearing the armor of Samurai. One is their leader, the other, a man from Earth. An Otherworlder who served the master of the Daemons until he met Hal. His name; Miyamoto Musashi. A man trained in the art of the Shinobi. Joining together, the Otherworlders have sworn to serve the king of Cent, Henry Lackland. A man Hal met on Earth. A man from Tera brought to Earth by a storm and returned in the same manner.Although the threat of the Daemons is over for now, Henry and the Otherworlders face an even greater threat. Henry's father is dead, murdered by the Duke of Sandford, Osborn Kennington, who has usurped the crown and placed his son on the throne. To solidify his power, Kennington has sent an army to find and kill Henry and all who serve him.Taking refuge in the castle at Tilden, Henry seeks allies to help him regain the crown. But while preparing to meet the approaching army, he learns of another threat.An invading horde rampages through the countryside of Cent on its unstoppable path south. An army determined to join the one sent by Kennington.With his new allies, legionnaires from Lantus, sea raiders from Southland, and the two Otherworlders, Henry prepares to defend not just Cent but all of Glenlock. The question is, can he succeed, or will Glenlock fall into chaos?
