This book was released on 1992 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout this final grant from AFOSR, the P.I. spent much of his time in the preparation of generic overviews of numerous major topics in diffusional phase transformations. These overviews dealt with homogeneous nucleation, interphase boundary structures in Ti-base alloys, effects of interphase boundary structure upon growth kinetics, shear vs. diffusional transformation mechanism (with emphasis upon linking macroscopic observations with processes proceeding at the atomic level), the mechanism (and definitions) of the bainite reaction and the influence of alloying elements upon the growth kinetics of grain boundary allotriomorphs of proeutectoid ferrite. A major overview of the ledge mechanism in vapor-crystal, liquid-crystal and crystal-crystal diffusional phase transformations, and a still broader overview of atomic mechanisms of diffusional nucleation and growth are nearing completion. Collaborative research with Dr. M.G. Hall of the University of Birmingham, U.K., on topics concerned with distinction between diffusional and shear mechanisms of transformation from the standpoints of crystallography and surface relief effects, has also made progress.

Available in PDF, EPUB and Kindle. Book excerpt: These studies on diffusional phase transformations in titanium and related alloy systems are intended to develop further the scientific base needed to design alloys based upon these transformations which may exhibit significantly improved combinations of mechanical properties. Kinetics of beta yields alpha sub m massive transformation were compared with those of grain boundary proeutectoid alpha precipitation in Ti-Ag and Ti-Co alloys, using measured or calculated nucleation and growth kinetics data and Cahn analysis of overall transformation kinetics of grain boundary nucleated reactions, successfully explained presence of massive transformation only in Ti-Ag and alpha allotriomorphs only in Ti-Co. New explanation developed, on thermodynamic grounds, for replacement of 'normal' proeutectoid alpha plates with a well-formed 'black plates' alpha + lower reaction temperatures. Bainite nodules in hypereutectoid Ti-Cr and in hypoeutectoid Ti-Co and Ti-Fe were found to exhibit misfit dislocation and ledge structures. Nodules in Ti-Cr grew at approximately volume diffusion-controlled rates; but reanalysis is now needed in terms of ledge mechanism. Eutectoid alpha is often found to differ slightly in orientation from adjacent proeutectoid aplha plates.
