| Abstract |
Densifications behavior of metal powders during hot compaction is investigated. Experimental data for both copper and tin powders support the mathematical model proposed by Kim and Suh. Linear equations are used to describe the pressure-densification measure relations at the instantaneous and equilibrium responses. The slopes of these equations are represented by a function of temperature to correlate hot compaction data with the micromechanical model analysis. A power law creep response for time dependent densification agrees well with experimental data at various pressures and temperatures. |
