Enhancement of Impact Toughness in Mild Steel Weldments under Low Temperature Applications
Key Engineering Materials, 2020In this research, mild steel weldments are tested by varying nickel content into the weld beads. Three mild steel plates have been joined using three electrodes with similar chemical composition except nickel content 0%, 9-11% and 19-21% respectively, by SMAW process and keeping heat input constant at all.

Microstructures and impact toughness of low-alloy high-carbon steel austempered at low temperature
Scripta Materialia, 2009We studied the microstructure and impact toughness of low-alloy high-carbon steel austempered at low temperature. Ultrafine carbide-free bainitic microstructure was obtained, which is composed of lath-like bainitic ferrite and retained austenite. The impact absorbed energy of austempered samples is much greater than that of the low-temperature tempered

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 ...

Effect of Low Temperatures on Charpy Impact Toughness of Austempered Ductile Irons
Journal of Materials Engineering and Performance, 2002Impact properties of standard American Society for Testing Materials (ASTM) grades of austempered ductile iron (ADI) were evaluated at subzero temperatures in unnotched and V-notched conditions and compared with ferritic and pearlitic grades of ductile irons (DIs).

Effect of residual aluminum on impact toughness of steel at low temperatures
Metal Science and Heat Treatment of Metals, 19591. The transitional embrittlement of low carbon steel depends on the contents of aluminum and the ferritic grain size. 2. The higher the rate of cooling of steel from the austenite range, the finer the grain and the lower the tough-to-brittle transition temperature.

Abstract The impact toughness of EN-GJS-400-18-LT ductile iron was measured by Charpy V-notch impact test at temperature between −80 and 20°C. The fracture properties were tested under instrumented impact loading. Total impact fracture energy, crack initiation and propagation energy, dynamic loads and the ductile to brittle temperature were measured.
