Compressive creep curves of Ti-Al ntermetallic obtained at 1100K and applied stress 50 - 500 MPa were investigated by means of constitutive equations. The procedure suggests an activity of two processes.The initial process is rapidly exhausted, the other process realizes a major part of the creep strain. The latter process is connested either with an increase (at high stresses) or a decrease (at low applied stress) of the internal stress. stress.
