Abstract Scope |
High entropy alloys (HEAs) have emerged as an innovative class of materials with diverse industrial applications, owing to their competitive properties such as enhanced mechanical characteristics, superior wear resistance, and excellent corrosion behavior. The incorporation of reinforcing particles, such as TiC and SiC, further enhances the mechanical properties of HEAs.
This study focuses on investigating the impact of in-situ TiC particles on the microstructure and mechanical properties of Nb-Ta-V-Ti HEAs, The HEA matrix composites were synthesized through a process involving high-energy ball milling, followed by spark plasma sintering. Structural characterization was conducted using X-ray diffractometry (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Compressive strength measurements of the HEAs were conducted at both room temperature and elevated temperature with a strain rate of 1x10-3s-1. The results revealed that the in-situ TiC-reinforced Nb-Ta-V-Ti HEA exhibited a yield strength of 2100 MPa at room temperature and 1090 MPa at 800℃. |
