Abstract

This paper describes a novel in-situ adjustment method of static magnetic field (SMF) for laser additive manufacturing, which realizes the change of grain morphology and weave structure without changing the composition and performing post-processing. The TC11 alloy was prepared by laser direct energy deposition (LDED) under static SMF. The results show that a transverse static SMF of 0.5 T effectively suppresses the tendency of columnar crystals to grow continuously along the build direction and the dominant weaving direction of 〈0001〉 texture, and reduces the anisotropy of the TC11 alloy.

静磁场在激光直接能量沉积过程中控制 TC11 合金的晶粒结构

本文介绍了一种用于激光增材制造的新型静态磁场（SMF）原位调节方法，该方法可在不改变成分和不进行后处理的情况下实现晶粒形态和编织结构的改变。在静态 SMF 下，通过激光直接能量沉积（LDED）制备了 TC11 合金。结果表明，0.5 T 的横向静态 SMF 能有效抑制柱状晶沿构建方向和〈0001〉纹理的主导编织方向连续生长的趋势，并降低 TC11 合金的各向异性。

期刊介绍： Materialia is a multidisciplinary journal of materials science and engineering that publishes original peer-reviewed research articles. Articles in Materialia advance the understanding of the relationship between processing, structure, property, and function of materials. Materialia publishes full-length research articles, review articles, and letters (short communications). In addition to receiving direct submissions, Materialia also accepts transfers from Acta Materialia, Inc. partner journals. Materialia offers authors the choice to publish on an open access model (with author fee), or on a subscription model (with no author fee).
