Abstract
This work explores the compound effect of tension twins and compression twins on extruded Mg-5Sn-0.3Li, with an emphasis laid on the microstructure and mechanical properties. To induce both tension twins and compression twins, Mg-5Sn-0.3Li in the cast condition was chosen and subjected to 5% pre-compression. Both the pre-strained sample and unstrained sample were then exposed to extrusion. Our results reveal that pre-strained Mg-5Sn-0.3Li rods exhibit higher overall mechanical properties including yield strength, ultimate strength and elongation to failure in the extrusion condition. The relevant mechanisms were discussed.
