Abstract
PURPOSE:To simplify die construction and to improve productivity of green compact by making super hard alloy of contacting part with alloy powder and Ni-Cr-Mo steel of the outer periphery and fitting by shrinkage-fitting both at the time of compacting powder of Fe-Si-Al series alloy into the green compact by compressing in the die. CONSTITUTION:In the powder metallurgy for using the Fe-Si-Al series alloy powder, at the time of producing of the green compact for the alloy powder, the part directly contacting with the Fe-Si-Al series alloy powder of inside first layer 23, middle core 22, lower punch 21 and upper punch 20, etc., in the die 19 shaping a cavity for compacting is made of the super hard alloy and second layer 24 in the die 19 is made of Ni-Cr-Mo steel, and both are fitted by the shrinkage-fitting, and also outside of the second layer 24 in the die 19 is made of ordinary steel and fitted into the second layer 24 by the shrinkage- fitting. By this constitution, at the time of taking out the green compact by raw material alloy powder, as the green compact is easily taken out without turning over the die 19, the productivity of the green compact is improved.
