【摘要】 在工业纯铜中加入微量锂能提高其再结晶温度。试验表明：加入０．０４％（质量百分数）锂，使冷拔后的工业纯铜的再结晶开始温度从４００℃提高到４４０℃。这是由于加入锂后，固溶于铜中，造成铜的晶格畸变，对再结晶过程中的位错运动与重排起阻碍作用，抑制再结晶过程的形核和晶界迁移，从而抑制再结晶，提高钢的再结晶温度。更多还原

【Abstract】 Trace lithium can improve recrystallization temperature of pure copper. The experimental results show that 0. 04% (mass percent) lithium improves the recrystallization temperature of pure copper from 400℃ to 440℃. The reason is that trace lithium dissolved in copper makes crystal lattice distort, hinder dislocations from moving and rearranging, restrain nucleating and grain boundary moving during recrystallization process.更多还原
