| 1 | 电磁压制多元金属混合粉末的压型方程显示文摘针对Ag-Cu-Zn-Sn系多元金属混合粉料制备无镉中温银基钎料进行研究,探索压坯密度与压制压力、压制模量及压制速率的关系。采取理论分析、工艺实验和软件拟合曲线相结合的方法,构建了电磁压制条件下的高速率压型方程,为电磁压制工艺的数值模拟分析提供数学模型和相应的参数,提高数值仿真的准确性和可靠性。该结果为Ag-Cu-Zn-Sn系多元金属混合粉料进行合理的电磁压制工艺设计提供一定的理论价值和工程实践指导意义。 | 高歌 胡建华 程呈 吴轩 张达 | 2015 | 中国有色金属学报2015，25，7： | 6 |
| 2 | Effects of temperature on the mechanical properties of Ti6Al4V powder compacts prepared by magnetic pulse compaction显示文摘The effects of temperature (0-500°C) on the compressive strength,hardness,average relative density,and microstructure of Ti6Al4V powder green compacts prepared by magnetic pulse compaction were investigated.The results show that with increasing heating temperature,the compressive strength first increases and then decreases with the maximum value of 976.74 MPa at 400°C.The average relative density and hardness constantly increase,and their values reach 96.11% and HRA 69.8 at 500°C,respectively.The increase of partial welding is found among the junctions of particles inside the compacts;there is no obvious grain growth inside the compacts within the temperature range. | LI Mini YU Haiping LI Chunfeng | 2010 | Rare Metals2010，29，3： | 3 |
| 3 | Microstructure and mechanical properties of Ti6Al4V powder compacts prepared by magnetic pulse compaction显示文摘Ti6Al4V powder compaction was performed by using magnetic pulse compaction in air at 200℃.Effects of process parameters such as voltage,capacitance,discharge times on the microstructure,compressive strength,hardness and relative density of compacts were investigated.The experimental results show that the relative density,hardness and compressive strength of compacted specimens increase with increasing voltage.In addition,the relative density and compressive strength of compacted specimens increase with the augmentation of capacitance in the range investigated.The relative density increases,the hardness firstly increases and then tends to be a fixed value;and the compressive strength firstly increases and then decreases from one to five times compaction.Both values of the hardness and compressive strength reach the maxima of HRA 69.1 and 1 062.31 MPa,at three times compaction,respectively.There are pores in and between particles. | 李敏 于海平 李春峰 | 2010 | Transactions of Nonferrous Metals Society of China2010，20，4： | 1 |
