Superplasticity of nickel-based alloys with micro-and sub-microcrystalliine structures

摘要

This paper will describe the generation of micro-and sub-microcrystalline structures in two Ni-based alloys that are typically strengthened by phases, such as gamma ' and gamma " + delta . The relationship between the superplastic behavior and microstructure will be discussed. High strain deformation rpcessing in the temperature range of 0.9
