Abstract
This paper describes the precision casting of Nicrosil and HH alloy hot sizing dies designed for forming close tolerance titanium alloy parts at high temperatures. A modified Shaw Process molding technique, with Nalcast crushed fused silica refractory grain is used to cast the dies to net dimensions. Foundry test results show that a variety of part shapes can be successfully formed to net dimensions on the cast dies. The use of precision cast dies will also achieve substantial savings by eliminating costly and time-consuming machining.
