Abstract
Fatigue crack propagation stage was investigated in Zn-22Al eutectoid superplastic alloy. Basic mechanical properties were established and tension-tension fatigue tests were performed following fracture mechanics methods. Fatigue crack extension rate curves at 296K and 375K were determined utilizing notched specimens. Tests were carried out under stress-intensity amplitude controlled conditions, in a frequency range between 0. 1 up to 80 Hz. In addition, monotonic tests were performed in order to elaborate on thermal effects and the strain-rate sensitivity. Experimental results and fractographic observations are described and analysed in terms of generalized view on fatigue processes in time sensitive materials.
