基于小冲杆实验方法的国产A508-3钢辐照前后的断裂韧度测定

摘要

建立了辐照前国产A508-3钢断裂韧度和小冲杆实验冲压断裂能之间的线性关系,利用该关系和辐照后小冲杆实验冲压断裂能计算得到了辐照后材料的断裂韧度.用Master曲线方法分别处理中子辐照前、后材料的断裂韧度实验数据,得到参考温度t0.%The linear relation between fracture toughness of the domestic A508-3 steel and fracture energy using small punch test before irradiation was established.Using this relation,the fracture toughness after irradiation was obtained.The fracture toughness data were dealt with Master curve and the reference temperature t0 was got.
