and element distribution. More importantly, Cu and the Invar alloy in the composites distribute continuously in a three-dimensional (3D) network structure. Cu/Invar interface diffusion is effectively... composites are considered as one kind of novel electronic packaging materials because they combine high TC of Cu with low CTE (<2×10-6 K-1) and high strength of the Invar alloys (Fe-36Ni alloy......

温度与应变速率对Invar 36合金变形行为的影响李细锋1,陈楠楠1,李佼佼1,何雪婷2,刘红兵2,郑兴伟2,陈军11. 上海交通大学模具CAD国家工程研究中心2. 上海飞机制造有限公司摘 要:在室温至900℃温度范围内,不同初始应变速率(8×10-5,8×10-4和8×10-3s-1)下,利用单向拉伸实验研究了温度与应变速率对Invar 36合金拉伸力学性能的影响,并选择室温,600和800℃进行三点弯曲实验,分析温度对Invar 36合金厚板回弹规律的影响.结果表明,Invar 36合金的屈服强度,抗拉强度随温度的升高而大幅降低;延伸率则先升高后降低,在600℃时出现峰值,达到69.2%,比室温提高了55%,这主要由于动态再结晶使塑性提高所致.当温度较低时(室温和500℃),应变速率对Invar......
at the bottom of the Al-Si alloy along the direction of super gravity. Then the refined silicon was collected by aqua regia leaching. The purity of the collected silicon is analyzed as 99.92%, which..., and later the refined silicon is recovered by super gravity. Al-Si alloy is a typically binary eutectic system. Alloying MG-Si with Al is a process of redistribution of impurities in silicon by taking......
