Wear behaviour of high entropy alloys CrFeNiAl0.3Ti0.3 and CrFeNiAl0.3Ti0.3–Ag roll bonded with steel
This study explores the feasibility of cladding CrFeNiAl0.3Ti0.3 and CrFeNiAl0.3Ti0.3–Ag high entropy alloys, produced via hot-press sintering (HPS), with commercial mild steel using the hot roll bonding (HRB) method. The bonding interface characteristics, mechanical properties, and tribological performance of these laminated composites were systematically evaluated. Microstructural analysis revealed that both high entropy alloys formed good metallurgical bonds with mild steel, exhibiting a straight interface free of visible cracks and oxidation products. Tribological investigations demonstrated that hot rolling significantly enhanced wear resistance, with specific wear rates decreasing by 70–82%. After hot rolling, the specific wear rate was reduced to (7.08–8.37) × 10–5 mm3/Nm for CrFeNiAl0.3Ti0.3 and (6.12–7.05) × 10–5 mm3/Nm for CrFeNiAl0.3Ti0.3–Ag across a temperature range from room temperature to 900 °C, compared to their pre-rolling values. These findings highlight the potential of hot roll bonding for integrating high entropy alloys with conventional materials, offering promising prospects for applications requiring high wear resistance and thermal stability.
期刊介绍：
The Journal of Materials Science publishes reviews, full-length papers, and short Communications recording original research results on, or techniques for studying the relationship between structure, properties, and uses of materials. The subjects are seen from international and interdisciplinary perspectives covering areas including metals, ceramics, glasses, polymers, electrical materials, composite materials, fibers, nanostructured materials, nanocomposites, and biological and biomedical materials. The Journal of Materials Science is now firmly established as the leading source of primary communication for scientists investigating the structure and properties of all engineering materials.
