Abstract: The paper presents impact energy results of thermal cycle simulated specimens of quenched and tempered fine grain structural steel S960QL. These results are obtained by examining notched Charpy specimens. Upon performed metallographic analysis and measured hardness, total impact energy is separated into ductile and brittle components.Keywords: quenched and tempered fine grain structural steel, welding thermal cycle, impact energy, cooling time t8/5Published in DKUM: 03.07.2017; Views: 1266; Downloads: 142 Full text (1,18 MB)This document has many files!

Abstract: The paper deals with research into dependence of hardness and impact energy of thermal cycle simulated specimens of fine-grained structural steel S960QL on cooling time from 800 to 500 °C and on tested temperature. Results were obtained by measuring hardness of HV 10 and by experimental testing of Charpy notched tubes on instrumented Charpy hammer. Total impact energy, initiation energy and fracture propagation energy needed for occurrence of fracture is also elaborated.Keywords: structural steel, quenched hardness, impact energy, cooling timePublished in DKUM: 03.07.2017; Views: 1150; Downloads: 113 Full text (185,44 KB)This document has many files!
