Název v původním jazyce

Fatigue and Tensile Behavior of Cast, Hot-Rolled, and Severely Plastically Deformed AZ31 Magnesium Alloy

Popis výsledku v původním jazyce

Experimental examination of fatigue behaviour of Mg alloy AZ31 produced by squeeze casting, hot rolling and equal channel angular pressing (ECAP) has been performed. Squeeze cast AZ31 had coarse grains; while the hot rolled material had the grain size of3-20 ?m. The material pressed 4 times at 200 °C using the ECAP technique, exhibited grain structure with the average grain size of about 1-2 ?m. It was shown that low- and high-cycle fatigue behaviour under symmetric loading at room temperature and withloading frequency of 20 Hz is strongly dependent on the technique employed in producing the alloy. ECAP improves the fatigue life of the material in the low-cycle region over that of the squeeze cast material. However, the fatigue life of AZ31 after ECAP was slightly lower than that of the hot rolled material. In the high-cycle region the hot rolled material and the material that underwent ECAP exhibit the same fatigue strength, which is superior to that of the squeeze cast alloy.
