Description
Summary:It was apparent from the papers presented that the research and development activity in the area of superplasticity and superplastic forming is of substantial interest world-wide, and a number of papers reported results that are considered to be significant and which may point the direction for future research that should prove fruitful. Noteworthy among these are 1) the activities addressing high rate superplasticity, through both alloy development and process concept studies, 2) computer modeling of the SPF process, including finite element methods coupled with 3-D color graphics displays of thinning characteristics, 3) superplasticity in ceramic and intermetallic compound materials, 4) solid-state joining (diffusion bonding) of aluminum alloys, 5) demonstration that there are microstructural concepts other than that of fully recrystallized structure which can lead to superplasticity, especially at high rates, and 6) significant extension in the state of understanding of the interrelationship between microstructural dynamics and superplastic properties, including fundamentals of superplasticity and cavitation development.
