Abstract:y reference to the test standard on bulletproof clothing of American Association for Justice(AAJ),the bulletproof properties of uncovered target plates of a new Ti-120 alloy were studied,and compered with pure titanium TA2,stainless steel,Nylon and keviar etc.The results showed that the new alloy,which has lighter density than steel and cheaper.than Nylon,keviar,has a good resistance to perforation and small hollow of shell crater.Therefore,the Ti-120 alloy plate with thickness of 2.6mm will be ideal materials of bulletproof clothing

Abstract:结合核动力堆用燃料包壳对锆合金耐蚀性能的要求，大范围考察了Ｎｂ含量为０．５％，１．０％，２．６％（ｗｔ％）的Ｚｒ—Ｎｂ二元合金及含Ｃｒ、Ｍｏ、Ｓｎ、Ｂｉ、Ｆｅ、Ｃｅ和Ｓｉ的Ｚｒ－１Ｎｂ及多元合金，共１７种成分的Ｚｒ－Ｎｂ系合金在４００℃，１０．３ＭＰａ水蒸汽中的长期腐蚀规律（达１８２天）。在腐蚀转折前，Ｚｒ－Ｎｂ系合金的腐蚀动力学曲线均近似于抛物线规律，而在转折之后存在与线性规律偏离现象。长期腐蚀增重的分析说明：通过合理的多元合金化，即增加或降低Ｎｂ含量，并主加Ｆｅ、Ｂｉ、Ｓｎ和Ｎｉ而辅加少量的Ｃｒ、Ｍｏ

Abstract:研究了ＴｉＮｂ（Ｙ２Ｏ３）连续纤维增强Ｔｉ－４８Ａｌ－２Ｇｒ－２Ｎｂ合金复合材料的界面及显微组织。研究发现：复合材料的弯曲强度比基体略有提高，弹性模量和挠度有所下降。在纤维和基体之间形成一层约１０～２０μｍ厚的α２－Ｔｉ３Ａｌ性层，近界面基体组织有片层化倾向。大量变形层错带和孪晶出现及界面位错墙的形成成为塑变及强化的主要机制。

Abstract:密切结合ＷＣ－Ｃｏ硬质合金工业生产中的质量检测工作，采用ＪＣＸＡ－７３３型电子探针显微分析仪和３０１４型Ｘ射线衍射仪，对合金的微观组织结构与性能：从断口形貌、ＷＣ－Ｃｏ合金的断裂行为、孔隙、夹杂物、η相的组织成分和结构等都做了较全面系统的分析和研究，实验表明合金断裂过程主要沿ＷＣ硬质相与Ｃｏ粘结相界面断裂或通过Ｃｏ粘结相断裂，很少是ＷＣ穿晶解理断裂，同时阐明了断裂源中的孔隙、夹杂物、η相是降低硬质合金断裂强度的重要结构因素，从而探讨了ＷＣ－Ｃｏ合金断裂的机理。该分析研究为质量检测水平提高到一个新的台阶，对

Abstract:he electrochemical deposition of aluminium from NaCl-AlCl3 molten salt system has been studied by using cyclic voltammogram.In the basic salts the species reduced at the cathode are AlCl4 ions,while in the acidic salts the species reduced are Al2Cl7 ions.There are equilibrium reactions between the ionic species,which influence the reduction of aluminium at the cathode.The reduction reaction of Al2Cl7 is quasireversible,and the reduction mechanism is very complicated.There may be some pre-chemical step or camo-catalytic reaction mechanism.
