The infiltration processing was conducted in a graphite vacuum furnace, and the processing parameters were set as heating to 1... that an elemental diffusion zone exists adjacent to the bonding interface. Fig.4 Variations of Fe, Cr and Ni contents of metal phase with distance from bonding interface 3.2 Microhardness test In order......
="ChDivSummary">Solid-state diffusion bonding is an advanced joining technique,which has been widely used to join similar or dissimilar materials.Generally,it is easy to observe the diffusion behavior during dissimilar bonding,but for similar bonding the diffusion behavior has yet been observed via experiments.In this study,the diffusion behavior at void tip was firstly observed during similar bonding......
of magnesium alloy (AZ31B) and aluminum alloy (6061) were welded using the vacuum diffusion bonding method. The composite specimens were continuously annealed in an electrical furnace under the protection..., resistance spot welding, explosive welding [10], laser welding, and the vacuum diffusion bonding. However, no matter which technique is used, brittle and hard intermetallic compounds, such as Al3Mg2......
