| Abstract: | Locomotive open screws break in the winter when using,and the fracture analysis is carried out on the fracture of the screw,and also,the heat treatment process of 2Cr13 material is carried on the experimental analysis.The impact of the materials is tested at different temperatures,and the brittle fracture reasons at low temperature are researched and analyzed systematically,and the suitable technical indicators of the materials for low temperature are put forward. |
