摘　　要：用试验证明了T8钢珠光体转变过程中产生的表面浮凸现象,从理论上分析了T8钢珠光体浮凸的形貌及其形成机制。结果表明,珠光体浮凸是由于奥氏体、铁素体、渗碳体各相比容不同,在奥氏体向珠光体转变时,比容增大,体积膨胀形成的。The surface relief appeared in pearlitic transformation of T8 steel is proved in test, its morphology and forming mechanism analyzed in theory. It is showed that having different specific volume from ferrite and cementite, the specific volume of austenite gets larger in its transformation to pearlite and its volume expanded, and so surface relief formed.
