摘　　要：Co-Pt永磁合金具有较高的各向异性和矫顽力,耐腐蚀,抗氧化,在磁存储领域具有良好的应用前景。在Co-Pt合金中添加稀土金属可以细化晶粒,还可改变合金的微结构。本文主要研究了退火温度和退火时间对添加稀土Dy的Co-Pt合金微结构的影响。Co-Pt permanent magnet alloy shows large anisotropy,high coercivity,good corrosion resistance and oxidation resistance,so it has a wide application prospect in the field of magnetic storage.Rare earth metals are often referred to as industrial monosodium glutamate.With addition of rare earth metal into Co-Pt alloy can grains be refined and the alloy microstructure be changed.In this paper,we mainly present the study of the effect of annealing temperature and time on the microstructure of Co-Pt alloy with Dy addition.

关 键 词：Co-Pt合金 DY 退火 微结构
