Abstract
ABSTRACT Titanium is widely used in the fields of medicine, industry, and biological science due to its excellent properties. In addition, titanium powder metallurgy (PM) is widely used in production because it could considerably reduce the cost. The most critical step in PM is powder compaction. Thus, the compaction equation is highly important in the prediction and analysis of powder compaction process. In this paper, the experimental data of titanium hydride powder and hydrogenated-dehydrogenated titanium powder were fitted using different compaction equations, and all the equations could obtain a high fitting degree (R 2 > 0.99) and a small error. The linear compaction equation could distinguish the powder type and different particle size distribution forms in the same type of powder through fitting parameters. The nonlinear compaction fitting equation could also analyse the contribution of powder densification mechanism through parameter calculation.
