A New Process For Making High Density Parts

摘要

A new P/M process for making parts potentially having equivalent or better properties than the ductile cast irons and densities up to 7.55 g/cm~3 is described. The process is in the early stages of development and is based on an essentially pioneer technology that does not depend significantly either on high pressure compaction or high temperature sintering. The process appears to offer considerable potential for economic production of large parts as the associated green densities and process temperatures that are required to implement it are typically below 6.8 g/cm~3 and 1175℃ respectively. What is currently known of the process and underlying technology is presented in detail.
