Abstrakt: Results of mechanical tests of WB36 steel for various thermal aging time bases are presented. Graphs of changes in strength and ductility properties of base metal and tensile strength of a welded joint depending on the aging time are presented. Results of tests for impact bending in the ductile-brittle transition temperature range for various exposures during aging are presented. Values of the ductile-brittle transition temperature for base metal and a welded joint are determined depending upon thermal aging time. [ABSTRACT FROM AUTHOR]
