Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

open access: yessteel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...

Effect of rare earth elements on martensitic transformation in low carbon steel

open access: yes, 1995
The addition of rare earth elements in 0.27C-1Cr steel can reduce the size of austenite grains and lath martensite, lower Ms, decrease residual austenite and retard the self-tempering process.

Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

open access: yessteel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Tailored Hardening and Isothermal Bainitizing of Additively Manufactured Nitrogen‐Enhanced Martensitic Chromium Steel

open access: yessteel research international, EarlyView.
Tailored heat treatments transform additively manufactured high‐nitrogen martensitic Cr steel from austenitic as‐built condition to high‐hardness states. Isothermal bainitizing at 250°C generates an ultrafine nanostructure and achieves higher hardness than conventional hardening and tempering, highlighting a promising postprocessing route for laser ...

Investigation of thermoplastic deformation behavior and microstructural evolution of CLF-1 steel for fusion blankets

open access: yesNuclear Materials and Energy
Reduced Activation Ferritic/Martensitic (RAFM) steel is widely recognized as the preferred structural material for fusion blanket modules. Among China’s primary candidate materials, Chinese Low-Activation Ferritic/Martensitic (CLF-1) steel requires ...

Variant selection in martensitic steels

open access: yes, 2019
The martensitic phase transformation in steel is one of the most famous solid state transformation because of its contribution in the development of the modern industry. This transformation from a face-centered cubic (FCC) high temperature phase, called the austenite, to a metastable body-centered cubic (BCC) low temperature phase, the martensite, is ...
