The Use of the ProCast Software to Simulate the Process of Investment Casting of Alloy Based on Titanium Aluminide TNM-B1 into Ceramic Molds

摘要

The possibility of simulation the process of casting of the titanium aluminide-based TNM-B1 alloy in the ProCast software is considered. The solidification parameters found using the ProCast and Thermo-Calc thermodynamic databases are compared. It is shown that it is preferable to use alloys available in the ProCast database for simulation. For various variants of the composition of the TNM-B1 alloy, we evaluated the conventional castability and showed that, in order to attain its maximal values, the alloys should be doped by the upper limit of admissible concentrations. A material for a cast mold called corundum ceramics (National University of Science and Technology "MISiS", Moscow) with properties differing from those of available in the database ProCast system for computer simulation of casting processes was proposed.
