Abstract
Researchers have considered powder compaction modeling to predict necessary compaction pressure at desirable density. This paper presented cold compaction modeling of titanium powder under high-power longitudinal ultrasonic vibration based on experimental tests. Superimposing high-frequency, high-power mechanical vibration on the compaction process could improve green density and density distribution. For this purpose, a special ultrasonic assisted cold compaction setup was designed and fabricated. CP titanium powder with size of <45µm compacted (up to 900MPa) at different ultrasonic powers (0, 100W, 150W, 200W, 300W). Then, a mathematical formulation was presented for ultrasonic-assisted cold powder compaction consisting of four terms: initial density, particle rearrangement, particle deformation, and ultrasonic vibration effects. The results showed that the presented mathematical model could predict accurately green compact density as a function of compaction pressure and ultrasonic power.
