Abstract:

A method of manufacturing ingots for use in making objects having heat, thermal shock, corrosion and wear resistance by formulating a composition of about 17-80% TiB. sub. 2 powder, about 0. 0 to 4. 0% Y. sub. 2 O. sub. 3 powder, and the balance of NiAl powder, the powders being thoroughly admixed, and placing the admixture into a mold in which it is subjected to a pressure of about 7000 psi and a temperature of about 1400. degree. C. for 20 to 140 minutes in an inert atmosphere, after which the mold is cooled and the ingot is removed and ready for use in manufacturing an object. In some applications the use of a ceramic filler material mixed with the powder is employed to improve the physical characteristics of the finished ingot.
