1.623.镁合金与面心立方(奥氏体钢)和体心立方(铝合金,铁素体钢)金属的晶体结构不同,具有不同的滑移系与塑性变形机制[2]. 在镁合金中,基面滑移是最容易开动的滑移系,室温下的临界剪切应力(Critical resolved shear stress,CRSS)约为其他非基面滑移的1/100[35],因此,在室温和低温下镁合金塑性变形以基面滑移为主,如图1所示为镁单晶在不同温度下的临界剪切应力[36...,Mg-2Al,Mg-2Y合金拉伸工程应力应变曲线(a)及真应力-应变拟合曲线(b) Fig. 4 Tensile stress-strain curves(a) and ture stress-strain curves(b) of Mg, Mg-2Al, Mg-2Y alloys 对纯Mg,Mg-2Al,Mg-2Y合金采用黏塑性自洽模型模拟了室温拉伸塑性变形过程(见图4(b)所示),并分析了Al和Y固溶......
, the effect of shear stress on the solid particles during the flow along the slope could also lead to the fragmentation of the dendrite arms, resulting in the non-dendritic structure [33]. Fig. 8......
