Recent work on Ti_3Al base alloy,TAC-1, developed in CISRI, including investigations of effects of modification in alloying and TMP on microstructural characteristics and mechanical behaviour,indicates that alloy TAC -1 is very promising structural material for a number of elevated temperature applications. Stuody dealing with a reverse relation between RT ductility and toughness found on TiA base alloy, TAC-2, led to development of a special heat treatment technique for producing a fine filly lamellar microstructure (FFL), which gives a high and balancing ductility and toughness. This is also of significance for promoting engineering applications of this alloy.
