Hardening of an Al-Cu-Mg alloy containing type I and II S phase precipitates
, 2010 The effect of different thermo-mechanical treatments on the hardness of the 2024 (Al-Cu-Mg) alloy was studied. Artificial ageing was conducted through heating at a constant rate to specific temperatures followed by rapid cooling.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Lubricated sliding wear behaviour of aluminium alloy composites
, 2005 Interest in aluminium alloy (Al-alloy) composites as wear resistant materials continues to grow. However, the use of the popular Al-alloy-SiC composite can be limited by the abrasive nature of the SiC, leading to increased counterface wear rates.

Quantitative Study of Internal Defects in Copper Iron Alloy Materials Using Computed Tomography
AlloysSemi-continuous casting is an important method for the large-scale production of high-strength conductive copper-iron (Cu-Fe) alloys in the future. However, serious peeling defects were found on the surface of cold-rolled strips during industrial trials.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Carburisation of ferritic Fe–Cr alloys by low carbon activity gases [PDF]
, 2011 Model Fe–Cr alloys were exposed to Ar–CO2–H2O gas mixtures at 650 and 800 °C. At equilibrium, these atmospheres are oxidising to the alloys, but decarburising (aC ≈ 10−15 to 10−13).

Effect of Al on the microstructure and high temperature oxidationperformance of Cu-20Ni-19Fe alloy
Journal of Hebei University of Science and Technology, 2021 In order to solve the problem of poor oxidation resistance of Cu-Ni-Fe inert anode at high temperature during aluminum electrolysis,Cu-20Ni-19Fe-xAl alloys (x=0%,6%,8%,10%) with different Al contents were prepared by vacuum melting method,and the alloys ...

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
