摘要: To explore the hot forming performance of ultra-high strength steel BR1500HS and its application prospects as auto-body parts, the microstructure and mechanical properties of BR1500HS before and after hot forming are comparatively analyzed by tensile test and metallographic analysis, and the crashworthiness performances of BR1500HS hot-formed parts and common B340LA cold formed parts are compared by a numerical simulation of vehicle frontal crash. The results show that the microstructure of hot-formed BR1500HS is mainly lath martensite, with both its yield strength and tensile strength are as high as over 2 times of that before hot-forming and the hot-formed BR1500HS parts have higher crashworthiness performance than B340LA cold-formed parts, indicating that ultra-high strength steel BR1500HS is suitable for manufacturing the structural parts of vehicle body. © 2016, SAE-China.
