具有典型时效析出强化特征的镀青铜以高强度、导电性、无磁性、耐磨性、耐蚀性等优异性能而著称,它广泛地应用于仪器仪表工业、电子电器工业。对铍铜的研究在国内外亦数不胜数。我们对QBe2合金加入稀土元素后发现稀土元素的加入能抑制晶界反应,使晶界不连续析出量减少。究其原因是稀土加入使合金净化和时效析出激活能升高所至。[图1]为稀 Bronze with typical aging precipitation-enhancing characteristics is known for its excellent properties such as high strength, electrical conductivity, non-magnetic properties, abrasion resistance and corrosion resistance. It is widely used in instrumentation and electronics industries. The study of beryllium copper is also numerous at home and abroad. After adding rare earth elements to QBe2 alloy, we found that the addition of rare earth elements can inhibit the grain boundary reaction and decrease the amount of non-continuous precipitation in the grain boundary. The reason is that the addition of rare earth alloy purification and aging precipitation activation energy up to. [Figure 1] is lean
