Abstract : The present report describes the research conducted on superplastic effects during phase changes in steels and titanium alloys. The report is in three parts: I. Transformation Plasticity of Ti-6A1-4V; II. Transformation Plasticity of Steels and Titanium in Torsion; III. Transformation Plasticity in Large Grain Pure Iron. Parts I and III deal with experiments where the specimens were subjected to a tensile load. Part II deals with studies where the deformation was applied in torsion. Superplastic aspects such as a linear relationship between flow per transformation cycle and applied stress and large plastic elongations were observed in all instances. Research on these programs is continuing. The organization of this report is such that each part is self-consistent, containing its own abstract, text, references, tables and figures for easy reference. (Author)
