摘要：

This study develops AA7075 aluminum matrix composites reinforced with TiB2 particles, created in-situ through aluminothermic reduction. Thermodynamic analysis confirms efficient TiB2 formation at 650-950 degrees C, enhancing composite strength. Mechanical tests, including compressive and tensile evaluations, reveal that treated samples show improved modulus and strength compared to untreated samples. Microscopy confirms a refined microstructure and uniform TiB2 dispersion posttreatment, enhancing mechanical performance and making the composite suitable for high-strength applications.
