摘要：
This study investigates the impact of paint baking on the macro and micro -mechanical properties of resistance spot welds in quenched and partitioned 980 steels. It is observed that paint baking enhances both peak load and energy absorption during cross -tension tests, as indicated by load -displacement curves. Four different regions were identified from the load -displacement curves after paint baking. An intriguing observation was a quick increase in the loading rate following a prior decrease, attributed to change in crack propagation behavior rather than improved work hardening. The study further simulated the upper -critical heat -affected zone using a Gleeble thermo-mechanical simulator to evaluate flow strength and work hardening. The Kocks-Mecking strain -hardening model was employed to analyze work hardening behavior in the studied conditions.
