摘要
近年来,低合金结构钢发展迅速,国内很多企业都在开发使用。硼元素在一定程度上能提高钢材的淬透性,使钢经过热处理后获得良好的综合力学性能。钛元素可以有效地细化晶粒,与适量的硼元素配合使用,可以改善焊接热影响区的韧性。该文研究了不同焊接材料、焊接工艺等对20MnTiB材料的力学性能和组织分布的影响,为低合金钢的广泛应用提供了参考。
In recent years, with the rapid development of low-alloy structural steel, many domestic enterprises are studying on it. Boron element can improve the hardenability of steel, and obtain good mechanical properties within heat treatment. Titanium element can be effectively refined grains, and used in conjunction with an appropriate amount of boron can improve the HAZ toughness. In this passage, we research how welding materials and welding process influence the mechanical properties and metallographie structure of 20MnTiB, which supplies reference for the wide application of low-alloy steel.
