Abstract

AbstractThe cold pressure welding of copper, brass, aluminium, and stainless steel has been investigated using thin-layer metal sandwiches produced by roll bonding and plane-strain indent welding. Shear tests were carried out to assess the level of bonding and scanning electron microscopy used to examine peeled surfaces from bonded specimens. Welding was found to be initiated by the formation of transverse cracks in the surface layers of the mating surfaces. These cracks coincide on both surfaces and are widened during deformation allowing extrusion of the base material through the cracks until a weld is formed. Extension of the surfaces is necessary for welding and the dependence of threshold deformation on the welding geometry is associated with the different surface behaviour. No recrystallization at interfacial regions was observed.

一些金属的冷轧和缩进焊接
摘要:研究了采用辊焊和平面应变压痕焊制备的薄层金属夹层对铜、黄铜、铝和不锈钢的冷压焊接。剪切试验用于评估粘合水平,扫描电子显微镜用于检查粘合样品的剥离表面。发现焊接是由在配合表面的表层形成横向裂纹引起的。这些裂纹在两个表面上重合,并在变形过程中被加宽,允许基底材料通过裂纹挤压,直到形成焊缝。表面的延伸是焊接所必需的,并且阈值变形对焊接几何形状的依赖与不同的表面行为有关。界面区未见再结晶。
