Abstract

It is shown that a new fine microstructure with significantly improved tensile properties can be generated in massively transformed, quenched and tempered samples of TiAl-based alloys. It is also shown that quench-cracking can be avoided in samples up to at least 20 mm diameter if samples are quenched into molten salt. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd.
