Abstract：

To analyze the microstructure, static-dynamic mechanical properties and load-bearing characteristics of anti-collision beams made of cold-rolled ultra-high strength martensitic steel HC1030/1300MS, the microstructures and fracture morphologies were used to observe by scanning electron microscopy. High-speed mechanical properties were tested via a hydraulic servo high-speed tensile testing machine, and static three-point bending and dynamic drop-weight crushing tests at 0.5 and 1 m heights were conducted. The results show that the strength of the material increases with the increasing of strain rate. The fracture morphologies exhibit the ductile fracture characteristics. With the increasing of strain rate, the three-region fracture feature diminishes, while the density and depth of dimples increase.Compared with the static loading condition, the maximum load and average load in the dynamic drop-weight crushing test at height of 0.5 m are increased by 12.5% and 10.5%, respectively. In the dynamic drop-weight crushing test at height of 1 m, compared with that at a height of 0.5 m, the maximum load and the average load are increased by 43.9% and 24.5%, respectively. The load-bearing characteristic of the anti-collision beam is increased with the increasing of the loading energy and speed, showing notable improvements in maximum load, mean load, and maximum displacement.
