一、前言 Ag—Cu复合材料的良好综合性能赢得了电子、计算、遥感等仪器仪表的广泛应用。随着现代技术和工业发展,不仅对材料提出了更高的综合要求,而且对白银的用量日益增多,量大面广。但白银资源有限。近年来全世界每年耗银量约一万三千吨,而产量只有一万吨。我国也是如此。所以白银短缺,供不应求是个世界性问题。为了解决这个矛盾和适应综合性能的要求,发达国家广泛采用了固相轧制连续复合、热轧、热压复合、自动连续焊、电镀、
I. INTRODUCTION The good comprehensive properties of Ag-Cu composites have won the widespread application of electronics, computing, remote sensing and other instrumentation. With the development of modern technology and industry, not only higher demands for materials have been put forward, but the amount of silver used is increasing day by day. But silver has limited resources. In recent years, the world consumes about 13,000 tons of silver each year, while the output is only 10,000 tons. The same is true in our country. So silver is in short supply and demand is a worldwide problem. In order to solve this contradiction and meet the requirements of comprehensive performance, developed countries have adopted a wide range of solid-phase rolling continuous composite, hot-rolled, hot pressing composite, automatic continuous welding, electroplating,
