Abstract:

A CALPHAD-coupled finite element model of dissimilar AZ31/ZK61 resistance spot welding was established in this work. The coupled effect of phase transformation and heat transfer was considered in this model, which presents the solid fraction contour evolution within the joint. During the cooling stage of AZ31/ZK61 resistance spot welding, a low-solid-fraction layer appears within the partially melted zone of the joint. The continuous liquation crack in the AZ31/ZK61 resistance spot weld exhibits a pattern similar to the low-solid-fraction layer plotted by the CALPHAD-coupled finite element model. In the case of AZ31/ZK61 resistance spot welding with a Zn interlayer, no low-solid-fraction layer appears. Due to the consideration of the coupled effects of phase transformation and heat transfer, the CALPHAD-coupled finite element model possesses the capability to analyze the liquation cracking susceptibility of ZK series magnesium alloy, which exhibits significant eutectic reactions during non-equilibrium solidification.
