Following the publication of a first set of four volumes of SGTE compiled thermodynamic properties of inorganic substances, which dealt with pure substances (Subvolume A) and a second set of five volumes with selected thermodynamic data for binary alloy systems (Subvolume B), this set of volumes focuses on data for ternary systems for one vitally important specific class of materials, steels. Various diagrams for each system are presented, calculated from a specially developed SGTE database for steels. Background information is also presented for each system. The fundamental equations used in evaluating the data are given in the introduction to the volumes and the models used in representing the data are also described.For this volume a steel database has been compiled, consisting of 11 elements: Fe, C, N, Cr, Mn, Mo, Ni, Si, Ti, V, and W. With this selection of elements a broad range of steels and cast irons is covered. The database allows not only calculations within the included assessed systems but it is also capable of interpolating into regions which are not well-known. Typical steel databases are confined to the Fe-rich corner. Contrary to that the present compilation covers the composition range of all evaluated systems as much as possible.

Over the past five years, through a continually increasing wave of activity in the physics community, supergravity has come to be regarded as one of the most promising ways of unifying gravity with other particle interaction as a finite gauge theory to explain the spectrum of elementary particles. Concurrently im portant mathematical works on the arena of supergravity has taken place, starting with Kostant's theory of graded manifolds and continuing with Batchelor's work linking this with the superspace formalism. There remains, however, a gap between the mathematical and physical approaches expressed by such unanswered questions as, does there exist a superspace having all the properties that physicists require of it? Does it make sense to perform path integral in such a space? It is hoped that these proceedings will begin a dialogue between mathematicians and physicists on such questions as the plan of renormalisation in supergravity. The contributors to the proceedings consist both of mathe maticians and relativists who bring their experience in differen tial geometry, classical gravitation and algebra and also quantum field theorists specialized in supersymmetry and supergravity. One of the most important problems associated with super symmetry is its relationship to the elementary particle spectrum.
