| 摘 要： | 通过对比试验发现:混合稀土含量对ZL201组织和性能都有很大的影响,当稀土含量在0.6%左右时,合金显微组织变得非常细小,硬度也达到很高的数值;但超过这个含量后,合金晶粒开始变粗,硬度也随之降低.最后,利用动力学的相关原理,证明了稀土元素发挥变质作用时最佳含量的存在.

| Abstract: | With contrast experiments it has been discovered that the content of mixed RE has a great influence on the properties and microstructure of ZL201.With a content of mixed RE reach 0.6%,the microstructure of the alloy changed extremely tiny and the hardness also achieved a very high value while upper this content,the crystal grain of alloy became coarse and the hardness reduced along with it.With the principle of dynamics related,it has been proven that the best content of mixed RE which displayadeteriorat-io... |
