Maraging steels are used in several industries, namely the molds industry. The determination of fatigue crack propagation resistance 18Ni300 maraging steel at Paris regime is a vital issue for safety-relevant components, which designed to work large number loading cycles before periodic inspections. main goal this analyze influence deposition plane angle and saline corrosion on growth samples p...

Additive Manufacturing (AM) technology produces parts in layers and offers design freedom (3D design), zero waste, reduced expensive tool material requirements, improved mechanical properties. Maraging steels have superior strength toughness with adequate ductility. The effect of aging process parameters on the final properties AM is enormous. In this study, effects heat treatment atmospheres t...

Laser Powder Bed Fusion (L-PBF) is a widespread additive manufacturing technology in industrial applications, for metal components manufacturing. Maraging steel special class of Fe-Ni alloys, typically used the aerospace and tooling sectors due to their good combination mechanical strength toughness. This work analyses heat treatment effect on microstructure hardness value 300-grade maraging ma...

Starting from the experimental data referring to the main parameters of the fracture surfaces of some 300-grade maraging steel reported by the classical work published in Nature 308, 721– 722 1984 , this work studied a the multifractal scaling by the main parameters of the slit islands of fracture surfaces produced by a uniaxial tensile loading and b the dependence of the impact energy to fract...

A precipitation hardened maraging TRIP steel was analyzed using a pulsed laser atom probe. The laser pulse energy was varied from 0.3 to 1.9 nJ to study its effect on the measured chemical compositions and spatial resolution. Compositional analyses using proximity histograms did not show any significant variations in the average matrix and precipitate compositions. The only remarkable change in...
