摘要
Abstract
In this paper,the surface quality,microstructure,internal texture and mechanical properties of three ERNiCrMo-3 welding wires at home and abroad were compared and studied.The results showed that the average relaxation diameter of the three welding wires was small,and the inclusion size of the 3#ERNiCrMo-3 welding wire was the smallest(0.047mm)among the three welding wires,and the inclusion area in 1#was 49.9%smaller than that of 2#(0.533%).Twin microstruc-ture appeared in all three ERNiCrMo-3 wires,and the twin boundary accounted for the largest proportion(9.02%)in 1#,and the 3#(1.85%)with the fewest twin boundary was nearly 79.49%less than 1#.The three welding wires of 1#,2#,and 3#all have obvious preferred orientation in the{111}and{110}crystal faces,and the texture density of the{111}crystal faces of 3#reaches a maximum of 23.75.The 3#with the largest tensile strength(1537MPa)is nearly 40.6%higher than the 1#(do-mestic)with the smallest tensile strength,and the grain boundary strengthening in 3#contributes 324.48MPa.关键词
