Title: Carburised sintered low alloy ferrous metal parts prodn. - involving carburising after sintering but before forgg
Inventor: HAYNIE ROBERT N
IPC: B22F3/17
Filed: 1976-10-05
Abstract: Fully dense, carburised, low alloy, ferrous powdered metal parts are obtd. by (a) briquetting a powder preform having a uniform carbon content and one or more surfaces which are required to be of certain case depth in the final forged form, (b) sintering at 2000-2100 degrees F, (c) carburising in a controlled carbon atmos. of rich endothermic gas, (d) forging at 1600-1750 degrees F to 99.6-100 % wrought density, and (e) quenching. The method is used esp. to obtain sintered AISI 4000 and 4600 type steels having sintered carbon levels of 0.22-0.37 wt.% e.g. for automotive transmission parts. By carburising before forging, carburising is effected rapidly since the parts have at most 70-90% ful density and the case depth in the preform can be less than that required in the final product. Additionally, metal flow during forging enhances the overall strength of the product.
