The impact toughness and mechanism of low-carbon steel fracture at low temperatures

Industrial laboratory. Diagnostics of materials, 2019
The goal of the work is to study the effect of severe plastic deformation (SPD) on the impact toughness and fracture mechanism of St3sp low-carbon structural steel within a test temperature range of 293 – 213 K. The issues of deformation processing of steel St3sp billets using SPD method in conditions of the equal-channel angular pressing scheme (ECAP)

Impact toughness of austenitic steels at low temperatures

Metal Science and Heat Treatment, 1967
1. If austenite undergoes no change in the impact test than the impact toughness decreases monotonically with decreasing temperatures. 2. The martensite forming during the test increases the work of formation of the crack but reduces the work of its propagation. The curves of the impact toughness have peaks.

Structural Turbulence of Pearlitic Steel 09G2S at Low-Temperature Impact Toughness

Physical Mesomechanics, 2020
The study explores the effect of helical rolling on the low-temperature impact toughness of pearlitic steel 09G2S. Helical rolling in two modes was performed at T = 850°C in six passes through rolls of varied diameters with air cooling (mode I) and water quenching (mode II).

Effect of residual aluminum on impact toughness of steel at low temperatures

Metal Science and Heat Treatment of Metals, 1959
1. 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.

Effect of Low Temperatures on Charpy Impact Toughness of Austempered Ductile Irons

Journal of Materials Engineering and Performance, 2002
Impact 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).

Enhancement of Impact Toughness in Mild Steel Weldments under Low Temperature Applications

Key Engineering Materials, 2020
In 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.

Effect of Mo content on impact toughness of CGHAZ in offshore engineering steels at different low temperatures

Metallurgical Research & Technology, 2023
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, 2012
A 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 ...
