【摘要】 本文利用图像分析仪和电镜分析了低碳钢不同铁素体晶粒尺寸时的显微组织,结果表明:随着铁素体晶粒的细化,珠光体逐渐消失,被“退化”珠光体或游离碳化物所取代.同时,在细小铁素体或形变诱导铁素体基体上有碳化物析出.更多还原

【Abstract】 The microstructures of low carbon steel in different ferrite grain size were studied by image analyzer and electron microscope, the result shows that the pearlite gradually disappear and substituted by degenerate pearlite or dissociated carbide, with the ferrite grain refinement.Meanwhile, the carbides precipitate on the matrix of refined ferrite or strain induced ferrite更多还原
