Effect of TiC on amorphous forming ability, microstructure, and thermal stability of Fe55Nb15Ti15Ta15 alloys

open access: yesFenmo yejin jishu
Due to the low amorphous forming ability and the poor room temperature plasticity, the engineering applications of Fe-based amorphous alloys were greatly limited. Based on the design concept of “near mixing enthalpy with effective atomic size difference”,

SiGeC alloy layer formation by high-dose C + implantations into pseudomorphic metastable Ge0.08Si0.92 on Si(100) [PDF]

open access: yes, 1997
Dual-energy carbon implantation (1 × 1016/cm2 at 150 and at 220 keV) was performed on 260-nm-thick undoped metastable pseudomorphic Si(100)/ Ge0.08Si0.92 with a 450-nm-thick SiO2 capping layer, at either room temperature or at 100 °C.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced 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 ...

Fabrication of Ti60Mn20‒xCu20+x (x=0, 10) amorphous powders by mechanical alloying

open access: yesFenmo yejin jishu
Based on the traditional composition design concept, a new design concept of “near-mixing enthalpy + effective atomic size difference” component imbalance diffusion was proposed in this paper, and it was first used to design the titanium-based amorphous ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced 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.
