【摘要】 钢材发生脆性断裂与两个条件有关 :温度和厚度。随着温度的降低和厚度增加 ,钢材的脆性增加。三点弯曲试验的结果表明 ,三种结构钢材脆性断裂随温度和厚度的分布具有明显的规律性。因此 ,本文从试验结果出发 ,分析了结构钢材发生脆性断裂的条件更多还原

【Abstract】 Brittle fracture of steel is related to two factors:temperature and thickness.Structural Steels tend to brittle fracture at low temperature and with high thickness.Three points bending experiments show that brittle fracture of three structural steels has obvious rules related to temperature and thickness.So based on experimental results,the author analyses the conditions for brittle fractures of structural steels in the paper.更多还原
