Abstract

The influence of compaction strategy (lubrication temperature and pressure) on springback and on sintering shrinkage of a 0.5%C and 1.5%Mo steel was investigated. The aim is to study dimensional and geometrical stability of this material when processed to obtain a sintered density above 96% of the theoretical one.

Specimens with 25 mm diameter and 25 mm height were compacted in in rigid die at different temperatures with different lubrication conditions and at pressures in the range 800-1200 MPa. They were sintered at high temperature in a vacuum furnace.

Green and sintered dimensions were measured by CMM to determine springback and sintering shrinkage and their anisotropy as well as the evolution in sintering of the geometrical features as a function of the compaction conditions.
