1.The results show that as the sintering goes on,the density of the pressing mixed powder blank increases and is stabilized at 7.96g/cm3after sintering at 950℃for 4 hours,which increases by 4.3% com-pared with unsintered blank at the same time,and internal oxidation of Cu-Al alloy particles ocnurs.
2.Lastly, discuss the technology of the thick blank cutting, Aiming at the characteristic and request of the thick blank cutting, design the forming die. And aim at how to decrease the pressing force and improve the life-span of the die, put the Essential of it’s punch design forward.
