摘　　要：利用透射电子显微镜研究321钢/Qd370qD钢爆炸焊接界面附近的纳米晶组织。结果表明,界面附近出现液态合金的调幅分解现象。过冷度越大,调幅分解的波长越小,形成的纳米晶越小。调幅分解波纹内的有序原子集团通过合并长大,形成初生的小晶体。Nanocrystalline structure adjacent the explosive weld interface of 321/Qd370qD steels plates was analyzed by transmission electron microscopy. The results show that there exists spinodal decomposition of liquid alloy near the interface. The more overcooling, the less wavelength of spinodal decomposition, and the smaller nanocrystals form. The order atom groups in the spinodal decomposition grow up through combination and come into being small initial crystals.
