Manufacturing sectors, including automotive, aerospace, military, and aviation, are paying close attention to the increasing need for composite materials with better characteristics. Composite significantly used in industry owing their high-quality, low-cost outstanding characteristics low weight. Hence, aluminum-based preferred over other traditional cost, great wear resistance, excellent strength-to-weight ratio. However, mechanical behavior of Al-based can be further improved by using suitable reinforcing agents. The various agents, whiskers, particulates, continuous fibers, discontinuous widely enhanced tribological comparable bare Al alloy. Further, advancement overall material obtained optimizing process parameters processing approach amount types reinforcement. Amongst available techniques, stir casting is most technique manufacturing material. reinforcement controls porosity (%) composite, while identify compatibility alloy through improvement composites. Fly ash, SiC, TiC, Al2O3, TiO2, B4C, etc. commonly agents AMMCs (aluminum metal matrix composites). current research emphasizes how different forms affect evaluates influence on tribo

To enhance the mechanical properties and wear resistance of novel high‐vanadium high‐speed steel (HVHSS), alloy is tempered at various temperatures (250, 260, 270, 280 °C) to optimize its comprehensive performance. The MC M 7 C 3 carbides are initially refined subsequently coarsened as tempering temperature increased from 250 °C. finest diffuse distribution minimal grain size (0.425 μm) achieved a 270 martensite content exhibits an inverse relationship with temperature, except °C, where dissolution induces secondary hardening during tempering. demonstrates optimal when hardness 64.1 HRC compressive strength 3039 MPa, primarily due fine second‐phase strengthening. Wear directly correlated these properties. At form strong bond matrix, preventing matrix splitting significantly enhancing abrasive spalling. This also inhibits oxygen intrusion into reciprocal processes. Additionally, mechanism evolves oxidative finally adhesive wear. study identifies process, offering valuable insights for further development high‐strength, wear‐resistant HVHSS.

Titanium alloys are applied in oil and gas development transportation to improve conditions because of their high specific strength corrosion resistance. However, the disadvantage poor wear resistance has become an obstacle developing titanium alloys. The friction properties pure TA3 alloy TA10 were tested under different loads forms using a reciprocating tester. Moreover, erosion was studied gas–solid results show that rate increases with increasing load. Under load 50 N, mass losses dry wet 0.0013 g 0.0045 g, respectively, while 0.0033 0.0046 respectively. While increased 70 loss even greater, reaching 0.0065 0.0058 g. include abrasive wear, adhesive oxidation wear. joint action various leads materials. simulated working conditions, rates 1.01 × 10−3 g/s 0.94 g/s. mechanism is same, including plowing, indentation cracking.
