Deformation Behaviour of AX91 and AJ62 Mg Alloys

Popis výsledku v původním jazyce

The deformation behaviour of two ternary magnesium alloys, AX91 and AJ62 were investigated in compression tests. The samples were deformed at temperatures between 20 and 300 oC at an initial strain rate of the order of 10-5 s-1. The deformation stressesdecrease with increasing temperature. Stress relaxation experiments were performed in order to reveal features of the thermally activated dislocation motion. Internal stress and strain rate sensitivity parameter were estimated. A decrease in the internalstress observed at elevated temperatures indicates the presence of recovery process (-es). A more detailed analysis of the strain rate sensitivity helped to identify the thermally activated processes occurring during plastic deformation. It was concluded that the deformation behaviour of the magnesium alloys depends on the activity of non-basal slip, which is strongly influenced by temperature.
