The paper deals with the impact toughness and fracture mode of the low-alloy 09G2S steel in the as-delivered state and in the condition after equal-channel angular pressing (ECAP) and annealing at impact bending in the temperature range of 293-203 [K]. The results on impact toughnessKCVand fracture mode of Charpy test specimens made of the 09G2S steel ...

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 ...

In order to reveal how microscopic factors affect the toughness and the occurrence of cleavage fracture of a low-carbon MnCrMoNiCu alloyed steel, a series of thermal treatments was performed on the steel employing a thermomechanical simulator. These involved reheating samples at different temperatures (950-1250 °C), producing different prior austenite ...
