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.
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).
