For the railway at low temperatures,this paper determined the maximum allowable loads on axle and maximum loads that would not cause injury of rail and its thermit welding joints.
随着机车轴重的增大,钢轨及其铝热焊缝承受轮载而产生的接触应力和剪应力将相应的增大,这将使钢轨及其铝热焊缝的轨头提前出现各种性质的伤损。
Basing on the results of the tensile test of rail steel and thermit welding which are popular domestically,this paper uses scanning electron microscope to analyze the fracture micro-morphology,finds the fracture microscopic mechanism,and lastly interprets the anti-fracture property at low temperature from fracture morphology viewpoint.
在国内常用钢轨钢材及其铝热焊缝的低温拉伸试验结果的基础上,利用扫描电子显微镜分析各自的断口微观形貌,得出其破坏的微观机理,进而从断口形貌的角度解释钢轨钢材及其铝热焊缝的低温下抗断裂性能。
