Microstructure and Strength of Welded Joints of Steel after Equal-Channel Angular Pressing

摘要：

The possibility of equal-channel angular pressing (ECAP) of steel billets with welded seams, the study of the microstructure and determine the characteristics of the weld strength and ductility is investigated. Two cylindrical work pieces (020 mm) of steel St3sp obtained by welding were subjected to ECAP. Investigation of the weld microstructure was carried out for three zones: base metal, weld metal and heat affected zone. Determining results the strength and ductility characteristics of the weld in the initial state and after ECAP are presented.
