Low temperature impact toughness of high strength structural steel

Thin-Walled Structures, 2018
Abstract Impact toughness properties of four kinds of high strength steel (HSS) were investigated with the nominal yield strength 460, 690, 800 and 960 MPa, respectively. The specialty of impact toughness among base metal, heat affected zone (HAZ) and weld metal were also compared and discussed.

Effect of martensite morphology and volume fraction on the low-temperature impact toughness of dual-phase steels

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2022
Abstract The influence of martensite morphology and volume fraction on low-temperature impact toughness of dual-phase (DP) steels was investigated by impact tests, nanoindentation tests, atom probe tomography (APT) and microstructural examination.

Microstructures and impact toughness of low-alloy high-carbon steel austempered at low temperature

Scripta Materialia, 2009
We 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

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.

Enhanced low-temperature impact toughness of nanostructured Ti

Applied Physics Letters, 2006
Impact toughness is one of the major mechanical properties for structural materials. It is generally observed that in coarse-grained materials the impact toughness decreases with decreasing testing temperature. Here, we report that the impact toughness of nanostructured Ti processed by severe plastic deformation is enhanced at low temperatures of −70°C
