Abstract

This article demonstrates the concept proof to manufacture parts of MgB₂ by Laser Powder Bed Fusion (L-PBF) coupled to Spark Plasma Sintering (SPS) by an optimization of the L-PBF and SPS conditions to limit the phase degradation and complete the sintering. Optimal L-PBF parameters were identified in order to obtain the material preforms with a minimal degradation of the MgB₂ phase, and then these preforms were sintered by SPS using an inert powder as matrix with a purpose to receive a mechanically more reliable product. Sintered samples show superconductivity state inherent for the raw material and demonstrate superconducting transition around 38 K according to the magnetic moment measurements.

激光粉末床熔合与火花等离子烧结耦合技术制备大块MgB2超导体。

本文通过优化激光粉末床熔合（L-PBF）和放电等离子烧结（SPS）条件，限制相退化，完成烧结，论证了用激光粉末床熔合（L-PBF）和放电等离子烧结（SPS）法制备MgB2零件的概念。为了获得MgB2相降解最小的预成形材料，确定了最佳的L-PBF参数，然后以惰性粉末为基体，用SPS烧结这些预成形材料，以获得机械上更可靠的产品。烧结后的样品显示出原料固有的超导状态，并根据磁矩测量显示出在38k左右的超导转变。

期刊介绍： Materials (ISSN 1996-1944) is an open access journal of related scientific research and technology development. It publishes reviews, regular research papers (articles) and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Materials provides a forum for publishing papers which advance the in-depth understanding of the relationship between the structure, the properties or the functions of all kinds of materials. Chemical syntheses, chemical structures and mechanical, chemical, electronic, magnetic and optical properties and various applications will be considered.
