摘要:

采用激光粉末床熔融(LPBF)工艺制备了纳米TiC颗粒改性Al-Mg-Sc-Zr合金，并对其晶粒组织、析出相等进行微观结构的表征，又结合常温浸泡、慢应变速率拉伸等腐蚀实验探究了TiC颗粒对LPBF制备的Al-Mg-Sc-Zr合金的微观结构与腐蚀行为的影响。结果表明：纳米TiC颗粒的添加导致大量的纳米Al₃(Ti, Sc, Zr)相产生，令LPBF制备的Al-Mg-Sc-Zr合金中柱状等轴双峰晶粒分布向全等轴晶粒的转变，这种精细的晶粒结构使得合金展现了优异的耐蚀性能及抗应力腐蚀性能。LPBF制备的TiC改性Al-Mg-Sc-Zr合金中的熔池边界及由于团聚形成的微米级TiC颗粒引发了合金的局部腐蚀，而这些易腐蚀的区域也成为了应力腐蚀开裂的选择性萌生及扩展的位置。

Abstract：

TiC nanoparticle modified Al-Mg-Sc-Zr alloy was fabricated via laser powder bed fusion (LPBF) technique. The microstructure and corrosion behavior of the as-fabricated alloy were systematically investigated through microstructural analysis of grain structures and precipitates combined with corrosion evaluations, including room-temperature immersion in 3.5% (mass fraction) NaCl solution and slow strain rate tensile tests both in air and 3.5%NaCl solution. The results indicate that the addition of TiC nanoparticle promotes the formation of abundant Al₃(Ti, Sc, Zr) precipitates of nano-size, which induces the transition from columnar-equiaxed bimodal grain distribution to fully equiaxed grains in LPBF-fabricated alloy. This refined grain structure significantly improvethe corrosion resistance and stress corrosion cracking (SCC) resistance. Furthermore, the molten pool boundaries and micron-sized TiC particles formed by the agglomeration of nano-particle serve as the preferential sites for localized corrosion, which also act as the preferential initiation and propagation regions for stress corrosion cracks.

Key words： laser powder bed fusion (LPBF) TiC particle Al-Mg-Sc-Zr alloy localized corrosion stress corrosion
