摘要
通过不同的热处理工艺,对稀土镧在纯净钢中单一合金化作用进行了研究.结果表明,稀土镧对纯净钢组织与性能有显著的影响.随着稀土含量的增加,晶粒细化,退火组织出现亚晶,淬火后的块状组织形貌发生明显变化.
Effect of single pure La alloying element on purity steel was investigated via different heat treatments, which shows that the influence of pure La on the microstructure and mechanical properties is very remarkable. With increasing the quantity of pure La, the crystal grains were refined and the annealed crystal grains precipitated the subcrystal grains while the quenched microstructure figure changed obviously.
