IPC: C22C38/00
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To obtain a preliminarily alloyed iron powder by subjecting a low alloy steel, containing specific small amounts of alloying elements, such as manganese, chromium, nickel, and molybdenum, to water atomizing and also to form metal parts with extremely high hardness by subjecting the powder to compacting, sintering, and termpering. SOLUTION: The alloy powder for powder metallurgy is composed of grains with a size of <=300 microns, preferably 50-100 microns average grain size. A molten low alloy steel, having a composition containing, by weight, 0.02% C, 0.3-0.9% Mn, 0.8-1.5% Ni, 0.5-1.3% Mo, and 0.3-0.9% Cr is crushed by a water atomizing method, by which the powder is obtained. Powder metallurgy is a method of manufacturing iron parts with high density by applying high pressure to a highly pure and practically uniform iron powder. At the time of sintering and hardening, the parts are partially or prefectly transformed into martensite in a cooling phase of sintering cycle.
