Abstract:
Experimental work has involved the preparation and initial evaluation of a wide range of cutting tool materials produced by a variety of techniques. An M2 high-speed steel base was enriched in vanadium, then forged into bar stock. Material containing up to 18wt% vanadium was fabricable, but none of the vanadium-enriched compositions were heat treatable without subsequent enrichment in carbon by solid-state surface carborization. This procedure should result in a tool material having a tough core with a hard, high-carbon surface layer. The casting of an M1 high-speed steel into an oscillating mold produced a much finer distribution of carbides than similar material cast into stationary mold. Initial atomization experiments using an M2 high-speed steel produced partially spheroidized particles generally finer than 80 mesh. No massive carbides were observed in the microstructures. Studies of liquid-phase sintered carbides included 2 general work areas. The first, utilizing iron-, nickel-, or cobalt-containing matrix phases, was concerned with the development of fine spheroidized carbides, principally VC. The second work area involved wettability and sintering studies of various carbides with high-melting matrix phases.
