Abstract
The mechanical properties of three magnesium alloys Mg4Li, LA43 and LA45 have been investigated in compression tests at temperatures between 25 and 200 °C. The yield stress and the maximum stress are sensitive to the testing temperature. The deformation behaviour of the specimens can be attributed to the occurrence of hardening and softening during deformation. Additions of aluminium to Mg4Li alloy increase the alloy strength. After stress relaxation of LA43 and LA45 alloy an increase in the flow stress is observed.
