Abstract

Boron treatment is a refining process that has historically been employed to improve the conductivity of 1xxx aluminum alloys by removing peritectic-forming elements (Ti, Zr, V, or Cr) in solution. However, in multicomponent alloys such as 6082 alloy, optimizing conductivity by boron treatment, while preserving other desired properties like strength or corrosion resistance that arise from Mn or Cr additions, presents a more complex scenario. This study addresses this challenge by investigating the kinetics of boron treatment in the 6082 alloy and the Al-B-Mn ternary system by laser-induced breakdown spectroscopy (LIBS), providing a unique opportunity to measure directly the composition of the molten alloy over time, enabling real-time mapping of the Mn, Cr, Ti, or V removal and their corresponding timescales after Al-B master alloy additions. Furthermore, this study highlights the potential to manufacture the 6082 alloy with optimized conductivity, as Al-B additions selectively removed peritectic-forming elements (V, Ti, and Cr) while retaining Mn, which is essential for strength and corrosion resistance.

激光诱导击穿光谱（LIBS）研究含锰铝合金硼处理对元素的去除

硼处理是一种精炼工艺，通过去除溶液中的包晶形成元素（Ti, Zr， V或Cr），历来被用于提高1xxx铝合金的导电性。然而，在6082合金等多组分合金中，通过硼处理来优化电导率，同时保留Mn或Cr添加所产生的其他所需性能，如强度或耐腐蚀性，呈现出更复杂的场景。本研究通过激光诱导击破光谱（LIBS）研究6082合金和Al-B-Mn三元体系中硼处理的动力学，解决了这一挑战，提供了一个独特的机会，可以随时间直接测量熔融合金的成分，从而实时绘制添加Al-B主合金后Mn， Cr， Ti或V的去除及其相应的时间尺度。此外，本研究强调了制造具有最佳导电性的6082合金的潜力，因为Al-B的添加选择性地去除了包晶形成元素（V， Ti和Cr），同时保留了Mn，这对强度和耐腐蚀性至关重要。
