本文的目的是研究爆炸焊接技术制造的铝-HSLA 钢和铝-双相钢双金属的显微组织和性能关系。双相钢是由 1.45Mn-0.2Si-0.186C HSLA 钢通过临界退火和水淬生产的。硬度。拉伸剪切强度。对爆炸焊接铝-HSLA钢和铝-双相钢的抗拉强度、韧性和显微组织进行了评价。两种双金属均具有直键合界面。还发现双相钢在双金属界面附近的塑性变形高于 HSLA 钢。双金属结合界面附近的硬度增加。拉伸和拉伸剪切强度试验表明，铝-双相钢优于铝-HSLA钢。此外，铝双相钢的冲击韧性明显高于铝高强度低合金钢。 (C) 2008 Elsevier B.V. 保留所有权利。
The aim of this paper is investigation of microstructure and property relationship in aluminum-HSLA steel and aluminum-dual phase steel bimetals fabricated by explosive welding technique. Dual phase steel was produced by intercritical annealing and water quenching from 1.45Mn-0.2Si-0.186C HSLA steel. Hardness. tensile shear strength. tensile strength, toughness and microstructure of explosively welded aluminum-HSLA steel and aluminum-dual phase steel were evaluated. Both bimetals have a straight bonding interface. It was also seen that plastic deformation of dual phase steel was higher than HSLA steel near interfaces of bimetals. The hardness was increased near the bond interface of bimetals. Tensile and tensile shear strength tests showed that aluminum-dual phase steel is superior than aluminum-HSLA steel. Also, impact toughness of aluminum-dual phase steel was found significantly higher than that of aluminum-HSLA steel. (C) 2008 Elsevier B.V. All rights reserved.
