Summary

Magnesium alloys generally are known to be brittle and have poor deformability at room temperature. This can be attributed to its hexagonal close packed lattice structure. Commercial magnesium alloys of AZ31 and AZ61 are studied and tested. Uniaxial compression tests were conducted under various temperatures to establish the strain-stress, strain–temperature relationships and its influences on the microstructure. The objective of this investigation is to establish the relationship between the deformation temperature vs. the strain-hardening, n value and strength coefficient, K value. The paper also attempts to establish a range of optimal temperature for the forging of wrought magnesium alloys.
