摘要

使用粉末板的金属添加剂是一项创新技术，旨在消除激光添加剂制造中的松散粉末。利用新型聚合物-粉末复合材料可实现对粉末的完全封装，从而降低安全风险以及与松散粉末相关的生产问题。这项研究通过改变新型复合材料的成分，展示了该技术的多功能性，从而提供更强、更硬、更具韧性的材料。研究表明，在不改变固溶体的情况下，打印出的高熵合金具有更好的机械性能。该技术未来将应用于多种材料和涂层领域。

Metal additive manufacturing using powder sheets (MAPS) of HEA CoNiCrFeMn: The effect of the polymer content on microstructure and mechanical properties

Metal additive using Powder Sheets is an innovative technology driven on eliminating loose powder in laser based additive manufacturing. The utilisation of a novel composite polymer-powder material enables the complete encapsulation of powder to mitigate safety risks and production issues associated with loose powder. This research demonstrates the versatility of this technology through varying the composition of the novel composite material, to deliver stronger, harder and more ductile materials. It is demonstrated that high-entropy-alloys can be printed with better mechanical properties while not altering the solid solution. Future applications arise in the field of multi-materials and coatings.
