Abstract Structural characterization of ten low-alloy tempered martensitic steels varied composition (C, Cr, Mo, Mn, and V contents) tempering temperature was performed to question the impact microstructural features on hydrogen state. Thermal desorption spectroscopy electrochemical permeation data for each alloy were acquired interpreted in view diffusion/trapping models. This large database p...

High-strength low alloy steels (HSLA) have been designed to replace high-yield (HY) strength steels in naval applications involving impact loading as the latter, which contain more carbon, require complicated welding processes. The critical role of HSLA-100 steel requires achieving an accurate understanding of its behavior under dynamic loading. Accordingly, in this paper, we experimentally inv...

The Master-alloy (MA) alloy route to promote a liquid phase during sintering has great potential reduce costs in low alloyed sintered steels, meanwhile enabling the introduction of innovative systems with Cr, Mn and Si. However, order successfully modify performance multi requirements must be met, including, for example, solubility base material, compatibility usual atmospheres, homogeneous dis...
