RESUMO
The data in this article is the supplementary data of the research article entitled "Comparable magnetocaloric properties of melt-extracted Gd36Tb20Co20Al24 metallic glass microwires" (Yin et al., 2020). The data shows the circular cross section of Gd36Tb20Co20Al24 metallic glass microwires with a diameter of â¼55 µm. The data also shows that the chemical compositions of microwires are basically uniform on macro-scale and micro-scale.
RESUMO
A novel metal matrix composite CrMnFeCoNi with Y2O3 as reinforcement phase was designed and manufactured by mechanical alloying and spark plasma sintering. After sintering at 900 °C for 5 min, the microstructure consisted of a FCC matrix and Y2O3 nanoparticles. The addition of 0.25 wt % Y2O3 increased the room temperature tensile strength of the CrMnFeCoNi base from 868 MPa to 1001 MPa, while the mechanical properties of the addition of 0.5 wt % Y2O3 composite decreased. In the meantime, the addition of Y2O3 had no significant influence on the coefficient of friction, while the addition of 0.25 wt % Y2O3 composite shows excellent wear-resistance.
