Abstract

The work is devoted to the experimental study of heat dissipation caused by plastic deformationand failure processes taking place in a titanium alloy Ti-4.2Al-1.6Mn. To investigate the spatial and timeevolution of temperature, a set of experiments has been carried out on plane titanium smooth specimens andspecimens with pre-grown centered fatigue cracks. The original mathematical algorithm for experimental dataprocessing has been applied to obtain the rate of heat dissipation generated by plastic deformation and storedenergy. It is shown that the stored energy is accumulated in titanium specimens undergoing fatigue tests, and atthe time of damage to fracture transition it is equal to zero.
