Description

The creep behavior of an investment cast near-gamma alloy Ti-48Al-2Nb-2Cr (at. pct) was investigated by determining the stress dependency and activation energy for steady-state creep deformation of this alloy, using the results of post-test microscopy to characterize the microstructural evolution after creep testing at high temperatures. The results of these examinations suggest that the mechanism of creep deformation in this alloy is a complex process which depends strongly on the specific stress and the temperature. 23 refs
