be characterized in several forms: volume change behaviour of unsaturated bentonite under different temperature, suction, and stress conditions; swelling pressure under constant volume conditions... of the high-density soil is significantly larger at the higher temperature, especially in the low-stress range. The same conclusion has been obtained from the swelling test of compacted boom clay under......
. Figure 7 presents the visual image that was recorded by a digital camera from the coated surface after 20-cycle thermal stress testing. It is obvious that there are no cracks, blistering, peeling......
measurement, mechanical polishing with colloidal silica was carried out to remove the residual stress layer for each sample, and the grain orientation map was obtained at a mapping step of 0.1 μm......

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......
