铍青铜(QBe 2)具有优异的物理、机械性能,用于制造弹性元件、耐磨零件、换向开关以及在高速高温下工作的轴承、衬套,波纹管等。由于铍青铜的塑性很差,锻造比较困难,所以,我们在承接QBe 2青铜改锻任务后,查找了多种资料,总结了各方面的经验,终于使QBe 2青铜的改锻获得了成功,现将QBe 2青铜改锻工艺的制订及实施介绍如下。一、QBe 2青铜的化学成分及其对合金的影响
Beryllium bronze (QBe 2) has excellent physical and mechanical properties for the manufacture of resilient elements, wear parts, reversing switches and bearings, bushings, bellows and the like that operate at high speeds and temperatures. Because beryllium bronze poor ductility, forging more difficult, so we undertake the QBe 2 bronze forging task, find a variety of information, summed up the experience of all aspects, and finally make QBe 2 bronze reforming has been successful, Now QBe 2 bronze forging process development and implementation introduced below. A, QBe 2 bronze chemical composition and its impact on the alloy
