The effect of Mo content on impact toughness of the coarse-grained heat-affected zone (CGHAZ) in 420 MPa offshore engineering steels after 15 kJ/cm welding simulations is studied at low temperatures of −40, −60 and −80 °C. With increasing Mo content from 0.08 to 0.16 wt.%, the average size of the prior austenite grain in the CGHAZ is decreased from 150

Enhanced Low-Temperature Impact Toughness of Ultra-Fine Grained SiCp/ZL108 Composites
Materials Science Forum, 2012A new strategy for increasing the low-temperature toughness of structural materials is in urgent need for overcoming the general rheotropic brittleness in coarse-grain state. Here, a unique phenomenon was observed that ultra-fine-grained (UFG) SiCp/ZL108 composites after severe plastic deformation (SPD) exhibit higher impact toughness at temperatures ...

Abstract An X80 (80 ksi, 555 MPa) pipeline steel was innovatively processed in the laboratory using the intercritical rolling process and excellent low temperature toughness was obtained. The Charpy v-notch impact energy was greater than 400 J at −80 °C and the shear fracture area in drop-weight tear test approached ~100% at −60 °C.
