| Abstract Scope |
A well-known technique for joining intricate parts is welding. However, the current liquid/solid-state approaches have shortcomings that still drive the quest for new innovative joining techniques. In this work, we assess the extension of the cold-spray technique to solid-state welding, a procedure we term cold-spray welding (CSW); this offers a "greener" and less expensive substitute to the conventional welding processes that frequently result in "soft" heat-affected zones (HAZs). Using AA 6061-T651 as a model material, results demonstrate that CSW does avoid significant disadvantages in conventional welding processes like Tungsten inert gas (TIG); these include detrimental phase transformation inhibition and HAZ suppression, even though TIG-welded samples have higher tensile properties. The analysis of CSWed components indicates that microvoids—microcrack initiation sites—from inadequate metallurgical bonding contribute to low yield strength. Finally, a mechanism for failure is established to guide future CSW optimization. |
