Abstract
Data on superplastic behavior of intermetallic alloys with high ordering en ergy, such as stoichiometric TiAl and Ti3Al and a number of alloys based on TiAl, with submicron grain size are summarized. The small grain size resul ted in a temperature range for superplasticity of 600-900 degreesC that is 200-400 degreesC lower than that for material with micron-sized grains. Thi s paper reports on the effects of grain size, composition and superlattice type on the low-temperature and high temperature superplastic properties of titanium aluminides. Low temperature and high-temperature superplastic pro perties of the titanium aluminides are compared. (C) 2001 Elsevier Science B.V. All rights reserved.
