China 23(2013) 2537-2542 Effects of solution treatment on microstructure and mechanical properties of Al-9.0Zn-2.8Mg-2.5Cu-0.12Zr-0.03Sc alloy Gao-song WANG, Zhi-hao ZHAO... March 2013 Abstract: Effects of additions minor contents of 0.03% Sc and 0.12% Zr and solution treatment on microstructure and mechanical properties of Al-9.0Zn-2.8Mg-2.5Cu alloy were studied......
of elongation. With large solid solubility in magnesium, elements like Al can improve the strength of Mg-Li alloys based on the solid-solution strengthening effects. As a result, in recent decades, Al was one...; precipitation strengthening 1 Introduction Magnesium alloys, with low density and high specific strength, have been widely used in automobile, aerospace and military industries [1-3]. However......
Bi precipitates in the β-Sn matrix. Solid solution strengthening and precipitation strengthening mechanisms in the β-Sn matrix increased the ultimate tensile strength and microhardness of the alloy... to Sn-0.7Cu solder alloys refined microstructure, reduced melting point and undercooling, and increased mechanical properties due to the solid solution strengthening effect. As reported by EL-DALY et al [25......
and the plasticities decrease after aging at a same temperature, and the aging strengthening effect increases. After solution at a same temperature, with the increase of the aging temperature, the strengths... Institute for Nonferrous Metal Research, Xi’an 710016, China) Abstract: The relationships between room-temperature tensile properties of TC18 titanium alloy and solution (α+β phase region) as well as aging......
