Hot Forming Springback and Control of 22MnB5 Boron and Magnesium Alloy Sheet

Abstract:

Starting with 22MnB5 boron and magnesium alloy sheet material forming temperature, cooling rate and phase deformation, the impact of cooling rate and temperature change on rebound during hot-stamping as well as the impact of factors such as sheet material thickness on high strength sheet material forming performance. The study shows that the initial conditions, temperature changes during thermal forming and phase deformation are the main factors affecting rebound. When the cooling rate is above the critical cooling rate, rebound increases dramatically. The sheet material thickness has important impact on rebound control and formulating parameters for thermal forming process.
