Quantitative Analysis of Phase Composition of Alloy TNM-B1 based on TiAl(γ) Titanium Aluminide

Aluminum and Magnesium Alloys
First Online:

The Thermo-Calc software is used to design isothermal and polythermal sections of the Ti – Al – Nb – Mo system as applied to a standard TNM-B1 γ-alloy based on TiAl intermetallic. It is shown that the use of special softwares is an effective tool for substantial lowering of the volume of experimental studies.
