Giant and reversible inverse barocaloric effects near room temperature in ferromagnetic MnCoGeB0.03 [PDF]

open access: yes, 2019
Hydrostatic pressure represents an inexpensive and practical method of driving caloric effects in brittle magnetocaloric materials, which display first-order magnetostructural phase transitions whose large latent heats are traditionally accessed using ...

Tensile properties of high- and medium-entropy alloys [PDF]

open access: yesIntermetallics, 2013
Abstract Equiatomic, face-centered-cubic, high- and medium-entropy alloys were arc melted, hot-rolled to produce recrystallized sheets, and tensile tested. The alloys having the compositions CrMnFeCoNi and CrFeCoNi exhibited a strong temperature-dependent decrease in strength with increasing temperature from −196 °C to 1000 °C, and a relatively weak ...

Coexistence of two types of short-range order in Si–Ge–Sn medium-entropy alloys

open access: yesCommunications Materials, 2022
Short-range chemical ordering has emerged as a key feature for controlling the properties of high-entropy alloys. Here, ab initio calculations reveal that two types of short-range ordering exist in Si–Ge–Sn medium-entropy alloys, suggesting that multiple

Designing eutectic medium-entropy alloys CoFeNiTax with outstanding mechanical properties

open access: yesJournal of Materials Research and Technology, 2023
The eutectic medium-entropy alloys CoFeNiTax (x = 0.4, 0.5, 0.6) were designed successfully based on binary eutectic systems and thermodynamics calculations in this study. With the increase of Ta content, the solidified microstructures evolved from hypoeutectic to full eutectic and finally to hypereutectic.
