Description
Patented Aug. 29, it 7 PATENT OFFICE imlrso STATES" PROCESS FOR nunovmG LYBDENUM ALLOY gIOKEL-MO- Werner Kiister, Dortmund, Germany, casino! to ereinigte tlieiimnV Stahlwerke Aktlengeaell- No. Drawing.

rapidity in air or by immersion in water or oil, 10 and finally heated to temperatures between 400 to 800 C., then the mechanical properties of the alloys will be very substantially increased in relation to those prior. to said heat treatment.
It for example, an alloy containing 75% of nickel and ct molybdenum be heated to 1100 C., quenched in water and annealed for one hour at 600 C. the hardness increases from 260 Brinell in the untreated state to 368 Brinell. It is to be understood that certain quantities 01 other metals such as Cu, Al, Fe, Co, Cr, Mn or non-metallic substances, may be combined with the binary alloys described, such as will not injuriously aflect the nature oi such alloys and which may to some extent modify their properties and render them more suitable for special requirements, without however affecting their ability to precipitation hardening, depending upon the fact that the principal part of the alloys consists oi nickel and molybdenum. Thus when in the ensuing claims I use the phrase the balance substantially nickel", I intend that the content of nickel and molybdenum shall be not less than about'85% of the whole.
l. Aprocess for obtaining alloys of high hardness consisting in forming an allo oi. 8 to 30% of molybdenum and the balance chiefly nickel and heating said alloy to a tern rature lying between 900 C. and the melting point oi the ,alloy, then rapidly cooling said alloyand subsequently annealing it at temperatures between 400 and 800 C.
2. An alloy containing 8 to 30% of molybdenum and the balance principally nickel, having high hardness produced by heating the alloy to a temperature lying between 900 C. and the melting point of the alloy, then rapidly cooling said alloy and subsequently annealingjt at a temperature between 400 and 800 C.
