Analyzing the Precipitation Effects in Low-Alloyed Copper Alloys Containing Hafnium and Chromium
MetalsCopper alloys containing chromium and hafnium combine elevated mechanical strength and high electrical and thermal conductivity. For the simultaneous enhancement of both material properties, precipitation hardening is the utilized mechanism.

THE MAGNETIC MOMENT OF IRON IN CHROMIUM AND CHROMIUM ALLOYS
Le Journal de Physique Colloques, 1978 The magnetic susceptibility of Cr 1-3 at% Fe, Cr 2 at% Si 2-3 at% Fe and Cr 0.5-1 at%V 3 at% Fe has been measured in the temperature region 4.3-340 K. It is inferred that isolated Fe atoms give rise to a temperature independent susceptibility and nearest neighbour Fe atoms nearly follow the Curie law in the commensurate spin-density-wave state.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing
Advanced Engineering Materials, EarlyView.The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys
Advanced Engineering Materials, EarlyView.Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

The wetting of silicon nitride by chromium-containing alloys
, 1995 The wetting of ceramic materials by metallic melts is the most important characteristic of brazing alloys. The effect of chromium additions to copper-base alloys on the wetting of silicon nitride was investigated.

Advanced Engineering Materials, EarlyView.The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...
