Abstract Scope |
MELD Manufacturing has developed a unique friction stir additive manufacturing process, a solid-state technique that prints large metallic parts from alloys that cannot be printed by other techniques. It requires no special chambers or vacuum and uses scalable equipment, with no practical limit to component size. With no melting required, the process produces a fully wrought microstructure. The MELD Process has exciting potential for a wide range of industries including aerospace, high performance auto/racing, industrial and defense. The process can not only make new parts, but also can add features and repair parts that have wear or other damage. This presentation will focus on the relationships among process and control parameters, the resulting microstructure and performance properties, including strength, fatigue, toughness, and corrosion, of high-strength 7075 and 7050. These builds compare favorably to conventional wrought products such as forgings and plate while reducing time and cost and producing complex geometries. |
