Hydrogen-induced delayed fracture of a martensitic steel with fine prior-austenite grain size

Journal de Physique IV (Proceedings), 2003
The influence of the grain size of the prior-austenite on the hydrogen-induced delayed fracture property was investigated for a medium carbon tempered martensitic steel (JIS-SCM440) with a tensile strength of 1400MPa. Thermomechanical treatment, which consists of a warm working at 873K by multi-pass bar rolling of tempered martensite and subsequent ...

The influence of austenitizing temperature on prior austenite grain size and resistance to abrasion wear of selected low-alloy boron steel

Archives of Civil and Mechanical Engineering, 2016
This study forms part of the current research on modern steel groups with higher resistance to abrasive wear. In order to reduce the intensity of wear processes, and also to minimize their impact, the immediate priority seems to be a search for a correlation between the chemical composition and structure of these materials and their properties. In this

Effects of Prior Austenite and Ferrite Grain Size on Fracture Properties of a Plain Carbon Steel.

1984
Abstract : An investigation was conducted into the effects of temperature, loading rate, and various microstructural parameters on the initiation of plane strain fracture of a plain carbon AISI 1020 steel. Ferrite and prior austenite grain sizes were chosen as the principal microstructural features to be investigated.
