摘要: Abstract Structural steels provide a broad spectrum of heat, creep and wear resistance at different microstructures hardness levels. Two steel grades were chosen for investigation simulated repair welds with parameters performed, aiming on the influence heat input during welding resulting microstructure high temperature abrasion resistance. The impact its dependence was evaluated within three-body test hot rig. Results indicate strong present microstructural phases entailed by parameters. Optimised low energy leads to stable progress conditions investigated materials.
