of experimental techniques to perform non-isothermal, unicxial and biaxial fatigue testa were described. A new miniaturised electrothermalmechanical test rig was presented and discussed. It enables testing...-of-phase superposition of thermal loads a cruciform biaxial fatigue testing machine has been developed. Special design features of both machines, and the specimens tested, as well as typical test results......
on the alloy plates after heat treatment. Fig.1 Orientation and dimensions of fatigue sample The XRD analysis was carried out on the Rigaku D/Max 2500. The fatigue test was taken on the MTS810 hydraulic...
