Abstract

1310821 Carbide spheroidisation in iron alloys MITSUBISHI KINZOKU KOGYO K K 7 April 1970 [30 Aug 1969] 16378/70 Heading C7A A sintered iron-base alloy containing 0À2 to 2% by weight of carbon and having a density of 5 to 7À2 g/cm<SP>3</SP> is compressed and then heated at 400-723‹C. As exemplified, an alloy of iron with 0À8%C. was sintered at 1130‹C. for 30 minutes to produce a bulk density of 6À4 g/cm<SP>3</SP>; it was then heated to 700‹C. repressed at 5 tons/cm<SP>2</SP> and heated for 30 minutes at 600‹C; also an alloy of 2% Ni, 0À8%C., balance Fe was sintered at 1000‹C. for 30 minutes to a bulk density of 6 g/cm<SP>3</SP>, repressed at room temperature and 7 tons/cm<SP>2</SP> and then heated for 30 minutes at 700‹C.
