中文摘要

本文以LZ91镁锂合金为研究对象，通过电子探针显微分析、浸泡实验和电化学实验研究了锻造和轧制变形加工对LZ91镁锂合金微观组织和腐蚀行为的影响。研究结果表明，LZ91合金锻造后，β-Li相的面积分数不变，晶粒尺寸减小。LZ91合金锻造后轧制（FR-LZ91），β-Li相的面积分数最高，晶粒沿轧制方向拉长。LZ91合金锻造后晶粒细化，晶界增多阻碍了浸泡过程中合金的腐蚀，提高了合金的耐腐蚀性。在所有实验合金中，FR-LZ91合金的腐蚀膜电阻和电荷转移电阻值最高，表明其具有最优的耐腐蚀性能，这是因为β-Li相高的面积分数促进了合金表面保护性产物膜的生成，阻碍了合金腐蚀。

Abstract

Abstract

The effect of rolling and forging on the microstructure and corrosion behavior of LZ91 alloy was investigated using an electron probe micro-analyzer, immersion and electrochemical tests. Results showed that the area fraction of the β-Li phase remained unchanged, and the grain size of the β-Li phase decreased after forging. The as-rolled forged alloy (FR-LZ91) exhibited the highest area fraction of the β-Li phase and the longest grains. The corrosion resistance of the forged LZ91 alloy increased due to grain refinement that prevented further corrosion during the immersion test. Among the experimental alloys, FR-LZ91 showed the highest resistance of corrosion film and charge transfer resistance values due to its protective film caused by the high area fraction of the β-Li phase.
