The tensile properties of three different carbonfiberreinforced carbon composites (C/C), mat C/C, 2D laminate and 4D C/C, were investigated under the combined influence of temperature and loading rate. From the experiments the following could be concluded: loading rate between 10-1-10 mm/min was val...

TC4-DT钛合金经高温恒应变速率变形后,进行三重热处理,具体工艺为:(920～960℃)×1 h水冷(WQ)+ (880 ～920)℃×1h WQ+ 820℃×1.5h空冷(AC),观察热处理后的微观组织.结果表明:TC4-DT钛合金950℃变形后,第一重热处理温度越高,初生等轴α相含量越少,在温...

用定量金相、扫描电镜和能谱分析等方法获取了用2种工艺冶炼的40CrNi2Mo钢中夹杂物尺寸特征参数,研究了这些参数对钢塑性的影响.结果表明:由于夹杂物的体积分数和尺寸比较小,夹杂物间距的增大,在塑性断裂时由夹杂物形成的微孔洞很难以内颈缩形式聚合,微孔洞间的局部剪切也不容易扩展.由此判断,真空自耗重熔...
