Abstract
PURPOSE: To obtain the sintered product having the excellent quality which has a small width of the distribution of grain size and does not leave pores, by molding the powder of the hard alloy such as WC-Co alloy, etc., sintering near the atmospheric pressure and, further after that, carrying out the secondary sintering at the higher pressure.
