Study of the Effect of Certain Elements on the Heat Resistance of Titanium Aluminade Ti3Al,

Abstract

Using a centrifugal method of bending, a change in the heat resistance of the Ti3Al compound was studied as a function of its alloying with one atomic percent with elements of group 4-8 and 4-B of the periodic system: Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Fe, Co, Ni, C, Si, Ge, Sn, and Pb. It is established that with an increase in the atomic number of an element the heat resistance within each group is increased. Alloying the Ti3Al with vanadium or molybdenum considerably increases the deformation property of alloys at high temperatures. Alloys based on titanium aluminide Ti3Al alloyed with one atomic percent W, Sn, Mo, Hf, Si, Zr, Ta, Nb, and V have the greatest heat resistance at 750C and stress of 25 kgf/sq. mm.
