MECHANICAL PROPERTIES OF POWDER TITANIUM AT DIFFERENT PRODUCTION STAGES--IV--MECHANICAL PROPERTIES AND CONTACT FORMATION IN POWDER TITANIUM PRODUCED BY DYNAMIC HOT PRESSING

摘要

The paper examines the effect of hot pressing parameters on the structure and properties of powder titanium. The initial porosity of the compact, sintering temperature and time, and temperature of dynamic hot pressing are varied. The resistivity and mechanical properties are used to assess the quality of the compacts after pressing. It is shown that powder titanium produced under optimal conditions compares well with commercially pure titanium produced with a conventional method.
