Paint baking of resistance spot welded joints of 2.0 GPa warm‐stamped medium‐Mn steel activates low‐temperature tempering, forming fine cementite in the fusion zone and enhancing toughness. Crack propagation resistance increases, shifting the failure mode from partial interfacial to complete pullout, with peak load and energy absorption rising ...

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 ...

Transformation super plasticity deformation of reduced activation ferritic/martensitic steel [PDF]
0000-0001-9016-2318Reduced Activation Ferritic/Martensitic (RAFM) steel is a promising candidate for the blanket structural materials of fusion reactors. One of the key issues in the use of RAFM for the blanket is its low workability.

MARTENSITIC TRANSFORMATION IN CuZnAl ALLOYS
The effects of the rate of heating and cooling, frequency and strain amplitude on internal friction (IF) related to the martensitic transformation in CuZnAl alloys were investigated.

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 ...

Some Results in Non-Linear Physics of Martensitic Transformation
Statistical thermodynamics of martensitic transformation is developed in the frame of the self-consistent field approximation. The accommodation mechanisms of the parent phase to the martensitic variant growth are described by the three order parameters.

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 ...

Serrations and stepwise austenite phase transformation were observed in cold‐rolled and annealed medium manganese steels. By in situ XRD experiments, these two phenomena were studied simultaneously. The results show that DSA leads to the creation of PLC bands and load drops in the specimen.

Dynamic behavior and Martensitic transformation of FeNiCoAlTaB high entropy alloy [PDF]
Owing to superior mechanical properties such as high fatigue life and high yield strength of many non-equiatomic high entropy alloys (HEA), a novel division of non-equiatomic FeNiCoAlTaB (NCATB) HEAs has been introduced.
