The capability of powder metallurgy (PM) process to produce high quality components/parts
is largely dependent on the control of process parameters. To obtain the desirable quality …

Pure titanium powder was pressed into two kinds of samples through high-velocity
compaction technology. The first was rings with 60mm outer and 30mm inner diameters and …

Abstract Three Ti-6Al-4V alloy powders with median diameters of 103, 66 and 44 μm,
respectively, were pressed by high-velocity compaction (HVC) technology and then sintered …

Electrically driven rapid vaporization of thin metallic foils is known to create very high
pressures, which can be harnessed for mechanical work. Recently, vaporizing foil actuators …

A production technique with the capacity to significantly improve the mechanical properties
of powder metallurgy (PM) parts is high-velocity compaction (HVC). To extend the usage of …

Ti–10Mo alloy powder were compressed by high velocity compaction (HVC) in a cylinderical
form of height/diameter (h/d) in die 0.56 (sample A) and 0.8 (sample B). Compactions were …

The discrete element method is used to investigate the high-velocity compaction process
with additional piston supports known as relaxation assists. It is shown that by incorporating …

To enhance the impact energy of powder high‐velocity compaction (HVC) and thus improve
the green density and mechanical properties of the resulting compacts, a mechanical energy …
