总结了国内外贝氏体相变理论研究领域的主要研究成果、争论焦点和重大分歧，涉及贝氏体相变过程伴随的表面浮凸效应、相变产物晶体学、贝氏体铁素体的“中脊”和“边脊”、下贝氏体碳化物的析出形态等；研究了贝氏体碳化物的不同特殊析出形态和α／γ相界面的巨型台阶；提出贝氏体铁素体可能按置换型原子体扩散控制台阶机制长大。
The main research results, controversies and major disagreements are summarized in the field of bainite transformation theory at home and abroad, involving the surface relief effect accompanied by the bainite transformation process, the phase transition product crystallography, the bainitic ferrite “Ridges” and “ridges” and the precipitated forms of lower bainite carbides. The different precipitated forms of bainitic carbides and giant steps of the α / γ phase interface were studied. Bainitic ferrite It may grow up by the step-by-step mechanism of displacement-controlled atomic diffusion.
