Dislocation structures below a nano-indent of the CoCrNi medium-entropy alloy

Iyad Alabd Alhafez et al.

Summary: This study investigates nanoindentation behavior of a CoCrNi medium-entropy alloy using diffraction-contrast scanning transmission electron microscopy and molecular dynamics simulation. The results show that at low temperature, the alloy exhibits increased hardness, higher dislocation density at the pit boundary, and more fragmented twinning boundaries indicating reduced twin growth.

Mechanical and dry sliding tribological properties of CoCrNiNbx medium-entropy alloys at room temperature

Yulin Liu et al.

Summary: The CoCrNiNbx medium-entropy alloys were successfully prepared via arc-melting and casting injection technique, displaying different categories and properties. Among them, the CoCrNiNb0.385 MEA is attracting attention for its full lamellar eutectic structure and excellent mechanical properties. In terms of tribological properties, this material exhibits the lowest friction coefficient and wear rate, attributed to uniform co-deformation between FCC and Laves phases in the eutectic MEA.

Strengthening mechanism of CoCrNiMox high entropy alloys by high-throughput nanoindentation mapping technique

Yonggang Tong et al.

Summary: The novel nanoindentation mapping technique revealed the influence of Mo content on the hardness of CoCrNiMox high-entropy alloys, with the fcc phase mainly strengthened by solute strengthening and the laves phase exhibiting high hardness. The lamellae colonies composed of alternative fcc and laves phases showed an intermediate hardness.
