Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

The studied X65MoCrWV3‐2 press hardening tool steel, produced via laser‐based direct energy deposition DED‐LB/M, exhibits a 15‐20% lower thermal conductivity than its conventionally produced equivalent when heat‐treated to operational hardness. The microstructural evolution during the employed direct tempering leads to anisotropic thermal transport, as

The effect of chemical inhomogeneity on the microstructure and properties of nanobainitic steel is investigated. A two‐stage isothermal heat treatment that produced a more uniform microstructure is designed. The first‐stage temperature is higher than the MS of depleted bands; conversely, the second‐stage temperature is lower than the first‐stage ...

This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.

This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress

ABSTRACT This study compared the shaping ability and remaining dentine thickness in mandibular molars prepared with traditional (TradAC) or ultraconservative (UltraAC) access cavities using Reciproc or XP‐endo Shaper instruments. Thirty‐two molars were scanned with micro‐CT before and after preparation to assess canal surface, volume, untouched walls ...
