Abstract:

Attempts were made to determine the effect of the amount of the NiAl binder and its composition on carbide-base alloy properties. Alloys on a TiC base, cemented by a NiAl binder, had a higher bending strength at 1000 degrees than at room temperature. Alloys based on titaniumtungsten carbide and containing about 16 TiC preserved their strength up to a temperature of between 900 and 1000 degrees when cemented with the NiAl binder. Alloys on a Ti-WC base, when cemented by the CoAl binder were stronger than similar alloys cemented by a NiAl binder. The strength of alloys on a TiC base at room temperature did not depend on the composition of the NiAl binder. At 1000 degrees the composition of the NiAl binder affected the strength of alloys. The composition of the carbide base had a significant effect on the strength of alloys which are cemented by NiAl and CoAl binders. Alloys on a pure TiC base and on a Ti-W base with a large TiC 64 TiC had great strength at room temperature. However, these alloys maintained and even increased their strength at temperatures of 1000 to 1100 degrees. Author
