Substitution of Ti by Nb in Maraging Steel: Effects on Strengthening Mechanisms and Crystallographic Behavior

steel research international, EarlyView.
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.

Direct Observation of Microstructure Effect on Martensitic Transformation in Multifunctional Ni–Co–Mn–Ti Alloy

Small Structures, EarlyView.
Microstructure engineering is utilized to control martensitic transformation of all‐d‐metal alloys and is directly observed via in situ Lorentz transmission electron microscopy. The appearance of magnetic vortexes and its evolution not only highlight a new potential application scenario for Ni–Co–Mn–Ti alloy in magnetic storage but also reveal the ...

Effects of Access Cavity Design on the Shaping Ability and Dentine Thickness Following Canal Preparation Using XP‐Endo Shaper or Reciproc

Australian Endodontic Journal, EarlyView.
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 ...

Role of evolving template on the transformation kinetics and microstructure of a product‐phase entropy‐stabilized oxide

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract We investigate the role of CoTiO3‐TiO2 template geometry on the microstructural evolution and growth kinetics associated with the formation of a product phase, CoTi2O5, in this reaction–diffusion system. For this purpose, the CoTi2O5 transformation pathways for three templates having distinct reactant‐phase grain sizes were compared and ...

Fracture of drilling head pipe connection due to quenching of heat affected zone (HAZ)

Metalurgija, 2015
The drilling head pipe connection is made of quenched and tempered steel 34CrNiMo6. The steel characteristic is high hardenability. Due to unsuitable and untested welding technology the heat affected zone (HAZ) cooling rate after welding surpassed the ...
