【摘要】 用多试样法则测定了SM490B钢焊接接头,在-20℃及-40℃下焊缝金属、母材、及热影响区以COD表示的裂纹扩展阻力曲线,得到了该焊接接头的表观开裂COD(δi),条件开裂COD(δ0.05),为使用者提供了断裂韧性数据。

【Abstract】 In this paper,welded joints of steel Sm490 were measured by means of many specimen method.The crack expanding resistance curves of weld metal.base metal and heat affeccted Zone have been determined at both -20℃and -40℃,which were described with COD.In addition,the initial toughness COD(δ i) and Conditional toughness COD (δ 0.05 ) of its welded joints have been obtained.The data of fracture toughness will be presented for the user.
