    摘要:

    本文通過自行設計配比一種新型高強塑積富B-Al合金材料。考慮到該種合金材料主要用于乘用車結構件，因此著重研究電阻點焊焊接性。同時借鑒國際焊接性評判標準ISO 14327-2004，設計了復雜焊接條件下的混合水平均勻設計實驗。找出了影響該材料點焊熔核飛濺的主要工況因素，并通過建立點焊熔核飛濺邊界曲線，從而有效地預測該材料點焊飛濺概率，更進一步的了解點焊熔核質量及點焊飛濺現(xiàn)象與焊接工藝、焊接環(huán)境等因素的相互關系，通過建立該材料點焊熔核力矩平衡方程與熔核膨脹應力數(shù)值仿真，深入分析點焊飛濺機理，在一定程度上促進了該新型高強塑積合金的實際應用。

    Abstract:

    A new B-Al-rich steel with high-strength and plasticity was developed and its RSW performance was studied when used as the structure materials of automobiles. The hybrid orthogonal experiments of complex welding conditions were implemented under the ISO14327-2004 standard and the main factors that can influence the spattering of nuggets were found. The boundary curves of nugget-spatter lobe diagram that could effectively predicate the expulsion rate of the developed steel were also drawn. The relationships among the nugget size, spatter, welding process and environments were further understood. A moment balance function of nugget was developed and the function-based numerical simulation for the coefficient of swelling stress was conducted. Therefore, the further understood spatter mechanism promoted the engineering application of the developed hot-stamped steels.
