Characteristics, benefits and applications of PST TiAl crystal
- Kyoto Univ. (Japan). Dept. of Materials Science and Engineering
The lamellar microstructures in gamma titanium aluminide alloys are of special interest since they are so common and persistent, not only under as-cast conditions but also after heat treatment. The authors have introduced a new approach for studying the lamellar structures by producing PST crystals of gamma titanium aluminide alloys and have been working to understand the material behavior at a fundamental level. Such work has considerably deepened their understanding of the microstructural characteristics and mechanical properties of the lamellar structures. It has also generated considerable interest in the DS(directional solidification)-processing of gamma titanium aluminide alloys. In this paper, first their work on PST crystals are summarized and then the prospects of the DS-processing of gamma titanium aluminide alloys are discussed based on the results of their recent studies.
