摘要:
A100、G50、G53、G54是4种常用的具有高强度、高韧性、良好抗冲击性等优异力学性能的高强钢，在工业制造领域得到了广泛的应用。对这4种高强钢分别进行了冲击韧性试验和平面应变断裂韧性试验，对其冲击功、平面断裂韧度和断口形貌进行了研究分析和比较。研究结果发现，4种高强钢承受冲击功和平面断裂韧度大小的顺序均为：A100>G50>G54>G53，表明A100高强钢具有优异的抗冲击性能和平面断裂韧性，而G53和G54虽然具有较高的静力学强度，但其冲击韧性和平面断裂韧性相对较低。研究结果为新型高强钢的设计、抗冲击结构的选材和优化设计提供了数据参考。
Abstract:
A100, G50, G53, G54 are four kinds of highstrength steel with high strength, high toughness, good impact resistance and other excellent mechanical properties, which have been widely used in the field of industrial manufacturing. In this paper, the impact toughness and plane strain fracture toughness of four kinds of highstrength steels (A100, G50, G53, G54) were tested, impact energy, fracture toughness and fracture image were also obtained and compared. Results showed that the order of both impact energy and fracture toughness was A100>G50>G54>G53, which indicated that A100 highstrength steel has excellent impact resistance and plane fracture toughness, while G53 and G54 have relatively low impact toughness and plane fracture toughness despite their high static strength. The result could provide a reference for designing and optiming antiimpact structures.
