Atomic-scale investigation of spinodal decomposition effects on hardness during nanoindentation of Fe-Cr alloys

Influence of Zr and Sn alloying on the deformation mechanism of Ti-12Mo-4Al metastable β titanium alloys: An atomic-scale study

The influence of zirconium and tin additions on the mechanical response of Ti-12Mo-4Al alloys was examined through tensile experiments, electron back-scattered diffraction (EBSD) analysis, fractography, and SQS-based first-principles calculations. The base alloy exhibits pronounced strain hardening with a peak hardenin...

Effect of adding titanium on corrosion and wear resistance of Al0.7CoCrFeNiTix high entropy alloy

High-entropy alloys based on the Al-Co-Cr-Fe-Ni system are considered promising materials for applications exposed to wear and corrosive environments. In this study, the effect of titanium addition on the microstructure, mechanical properties, tribological performance and corrosion behaviour of Al0.7CoCrFeNiTix alloys...

Effect of Cu and CuP Additions on the Microstructure and Nanoindentation‐Based Fracture Behavior of CoNiAlSi Ferromagnetic Shape Memory Alloys

In this study, the microstructural and mechanical performance of CoNiAlSi‐based ferromagnetic shape memory alloys was comparatively investigated using a base CoNiAlSi alloy and Cu‐ and CuP‐modified derivatives produced by vacuum induction melting under identical heat treatment conditions. SEM, EDS, XRD, and DSC analyse...

Investigation on the Deformation Mechanisms of an Ultrafine-Grained AlCoCrFe2Ni Eutectic High-Entropy Alloy

Gradient Microstructure Evolution and High-Temperature Water Corrosion Behavior of Surface Mechanical Attrition Treated Alloy 600MA

Gradient-nanostructured Alloy 600MA was fabricated via surface mechanical attrition treatment (SMAT) for 0–180 min. Pre-corrosion XRD confirms that SMAT with severe plastic deformation does not induce phase transformation of the γ-FCC Ni-Cr-Fe matrix, while progressive peak broadening verifies grain refinement and accu...

Study on the Microstructure, Wear, and Corrosion Resistance of W, Ni, and Co-Doped Fe-Alloys Processed by Solid-State Sintering

Iron-based alloys with compositions Fe 3 CWNi, Fe 3 C10WCo, and Fe 3 CWNiCo were synthesized by solid-state sintering at 1400 °C. This study investigates how additions of nickel (Ni), cobalt (Co), and tungsten (W) enhance the microstructure, wear resistance, and corrosion behavior of the prepared alloys. Micros...
