分类号:TG146.22;TG376.2 文献标志码:A Microstructure and mechanical properties of ZK60 magnesium alloy processed by T-shape channel pressing KONG Jing, HOU Wen-ting, PENG Yong-hui... of Technology, Guangzhou 510640, China) Abstract: ZK60 magnesium alloy was deformed by a new process of severe plastic deformation(SPD)-T-shape channel pressing (TCP) from 1 pass to 4 passes at 673 K using......
that the clad tubes with good bonding properties possess the interface in wave and straight shape. The Fe/Al clad tube was used to manufacture the T-shape by hydro-bulging. It is found that the good-bonding interface of the Fe/Al clad tube plays a dominant role in the formation of the T-shape. Key words: Fe/Al clad tube; bonding property; interface; plastic deformation; T-shape; hydro-bulging 1......
Loading curves of base metal and heat affected zone metal 式中:DVGM为孔洞成长损伤指数,可当作只与模拟结果有关的需求参数;T为应力三轴度,T=σm/σe,σm为平均应力,σe为von Mises等效应力;为等效塑性应变;A为应力三轴度系数,需要依据材性试验结果校准;为材料单调加载时的损伤极限承载能力,可理解为材料性质,亦需要校准.对结...VGM方法预测出的试件断裂时刻,与实测数据相比误差不超过4%,说明断裂参数的识别结果准确. 2 T形对接接头力学性能试验 2.1 试验方案 采用8 mm厚钢板分别加工成5,6和8 mm共3种不同厚度板件,与机加工的Q460钢底座经手工电弧焊单面成形全熔透焊接技术立焊成T形接头,焊材与材性试件的相同.焊接时设置引弧板,机械处理,焊后保温缓冷.考虑被连接板件间的夹角多样,底座上表面分别加工成与钢板夹角......
