Title :Dynamical High Speed Compaction of Metal Powder
Authors :Miyagi, Kiyohiro
Authors alternative :宮城, 清宏
Issue Date :1-Sep-1975
Abstract :In this paper Experimented on the dynamical compaction of metal powder and compared the results with theoretical calculation. Using a rubber propelled press that passed through the press guide and directly impacted on the face of the powder in a die. The velocity of the press was controlled by changing the number of rubber bands. Using an acryl plate of appropriate strength, an author observed the progression of both the press and the shock wave that were produced. On the theoretical calculations an author overlooked the elastic recovery factor; the effect of the kinetic state of powder and the friction between the powder and die wall; the effect of the air that was mixed with the powder particles. On both experimental and theoretical calculation the final density and shock wave velocity were examined.
