HEAT TREATMENT OF NICKEL BASE ALLOYS

1321458 Heat treating nickel alloys CABOT CORP 22 June 1970 [20 June 1969] 30109/70 Heading C7A An alloy containing in percentage by weight Mo 3-12 (replaceable by 3-15 W) is solution treated at 2250‹-2300‹F, quenched, cold worked to shape, heated at 2250‹ -2300‹ F for not more than 1 hour, quenched and aged at 1100‹ -1350‹ F for 24 to 100 hours. The solution treatment quenching and cold working steps may be repeated as necessary. The treated alloys have dispersed primary monocarbides of less than 5Á and finely dispersed mono carbide particles of less than 250Š.
