摘要

MELD是用于沉积金属或金属基复合材料的固态热机械工艺,不同于基于能束的金属增材制造工艺,也不同于基于片材层压的固态金属增材制造工艺,其具有可扩展、开放式操作、高沉积速度、产生近锻造微观结构、适用材料范围广、应用领域多等特点,已开始在战地废金属回收再利用、高抗弹性能装甲防护涂层制备等领域获得应用,具有良好的军事应用前景。
        MELD is a solid?state thermo?mechanical process for deposition of metal or metal matrix composites(MMCs). MELD is different from the beam?based metal additive manufacturing process and the sheet lamination?based solid?state metal additive manufacturing process. MELD is a highly scalable,open atmosphere process with high deposition rate,near wrought microstructure,high flexibility and freedom in feed material. MELD has been used as a method for recycling battlefield scrap metal and developing fully dense nano?crystalline metallic coating with a high ballistic resistance. MELD has good military application prospects.
