| 1 | CuZn37黄铜板料微塑性成形中的尺寸效应研究显示文摘为研究金属微塑性成形特点,对厚度不同及粗细两种晶粒尺寸的黄铜箔试样进行了单向拉伸和微弯曲实验,并采用经典塑性理论和应变梯度理论对弯曲回弹角进行了预测.粗晶粒板料试样单向拉伸实验表明,CuZn37黄铜的硬化曲线存在一种明显的尺寸效应,即板料厚度越小,屈服强度越高.弯曲回弹实验结果也存在另一种明显的尺寸效应现象,即板料厚度越小,回弹角越大.对这两种尺寸效应产生的原因进行了分析,指出应变梯度硬化对微成形工艺过程有重要影响. | 李河宗 董湘怀 王倩 申昱 DIEHL A HAGENAH H ENGEL U MERKLEIN M | 2011 | 材料科学与工艺2011，19，4： | 12 |
| 2 | 采用应变梯度硬化模型预测黄铜薄板微弯曲弯矩显示文摘通过黄铜板料微弯曲实验,发现其弯曲弯矩存在明显的尺寸效应现象,随板料厚度的减小,弯曲弯矩增大.采用经典塑性理论和不同的应变梯度理论对微弯曲弯矩进行了预测,对比分析结果表明:修正的Nix-Gao模型的预测结果更接近于实验结果,并且得出了合理的内禀尺寸表达式;该内禀尺寸与材料的剪切模量、初始屈服极限、柏氏矢量和板料厚度方向上的孪晶数有关. | 李河宗 董湘怀 申昱 Alexander Diehl Hinnerk Hagenah Ulf Engel Marion Merklein | 2011 | 上海交通大学学报2011，45，11： | 2 |
| 3 | 用高氮钢制造复杂高强度零件(英文)显示文摘High performance components, e.g., fasteners, nowadays are usually made out of cold forged and heat treated steels like steel 1.5525 (20MnB4). To overcome the problems of heat treatment, e.g., low surface quality, new workpiece materials for cold forging should be found to achieve the needlessness of heat treatment after cold forging. One possible material is given by high nitrogen steels like steel 1.3815 (X8CrMnN19-19). Due to the high strain hardening of these materials the process and tool design for an industrial batch process are challenging and should be conducted by FE-simulation. The numerical results show that, high strength tool materials, like PM-steels or cemented carbides, in most cases, are inevitable. Additionally to the selection of suitable tool materials, the tool layout should be developed further to achieve a high loadability of the tools. The FE-models, used for process and tool design, are validated with respect to the materials' flow and occurring forming force to assure a proper design process. Also the comparison of strength of components made out of steel 1.5525 in quenched and tempered conditions and steel 1.3815 in strain hardened condition is done. The results show that the component made of steel 1.3815 has a significantly higher strength than the component made of steel 1.5525. This shows that by the use of high nitrogen steels a high performance component can be manufactured by cold forging. | Hannes NONEDER Marion MERKLEIN | 2012 | 中国有色金属学会会刊:英文版2012，22，S2： | 2 |
