Effect of High Temperature Solid Solution Treatment on Microstructure and Mechanical Properties of Mg-15Gd-2Zn-0.6Zr Alloy AITranslate
Abstract AITranslate
The microstructure and mechanical properties were investigated of Mg-15Gd-2Zn-0.6Zr alloy after solid solution treatment at 510 ℃for 20 hwith optical microscope（OM）,X-ray diffraction（XRD）,scanning electron microscope（SEM）and mechanical tests.And the experimental results show that as-cast Mg-15Gd-2Zn-0.6Zr alloy is mainly composed of dendriticα-Mg substrate and interdendritic（Mg,Zn）_3Gd eutectic phase.After solid solution treatment,phase composition of the alloy is almost unchanged,but the morphology of（Mg,Zn）_3Gd phase changes from continuous network to isolated islands and its volume fraction decreases from 19% to 9%.No long-period stacking ordered structure is observed in the solid solution alloy.Under tensile conditions,the solid solution alloy exhibits lower yield strength of 176 MPa,but improved yield strength of 277 MPa and elongation of 12.8% than as-cast alloy,showing excellent comprehensive mechanical properties.Under compression conditions,the compressive mechanical properties of ascast alloy and solid solution alloy exhibit a small difference,and both have better mechanical properties under compression conditions than under tensile conditions.
