摘要
The effects of solution and ageing treatment（T6）on microstructure and tensile properties of as-extruded Mg-10Gd-3Y-0.6Zr（massfraction.%）alloy were investigated.The results show that after T6 treatment，the diameter of grain increases to 20μm.As the second phases dissolve into the matrix，the smaller and denser β＇ phases precipitate inside the grains.After T6-treatment，both yield strength（TYS）and ultimate tensile strength（UTS）are increased.Comparing with that in only ageing condition（T5），the UTS and TYS increased from 365 MPa，285 MPa to 400 MPa，310 MPa，respectively，but the elongation decreased from 7.0% to 3.5%.It has been found that the effects of precipitates on the strength are stronger than that of the growth of grain size.
