The effect of solution treatment on aging behavior and mechanical properties of AA2024-TiB2 composite synthesized by semi-solid casting

Abstract: AA2024 reinforced with varying amounts of titanium boride (TiB 2) was developed using stir rheocasting to study the effect of solution heat treatment on aging behavior and mechanical properties. The developed specimens were subjected to solution heat treatment at 490 °C for 1, 2.5, and 5 h, followed by artificial aging at 190 °C for an aging duration of 1-12 h. The metallurgical characterization was done by x-ray diffraction, optical microscopy, and field emission scanning electron microscope and mechanical ch… Show more

“…Currently, a wide range of vacuum deposition techniques (PVD, CVD) provide an ability to precisely control the deposition process of coatings [4][5][6][7][8][9]. Titanium, zirconium and hafnium diborides and composites based on their matrix have the highest resistance to thermal influence and oxidizing [10][11][12]. Films produced at proper conditions can be used for protective coatings in tribo-systems and cutting tools to enhance their durability.…”

“…Archimedes principle-based density is calculated experimentally and is compared with theoretical densities, and the calculated % porosity of the HMNCs is presented in table 2, figures 6 and 7. Observation from the experimental density and % porosity values presents that TiB 2 and CNTs reinforce inclusion, and porosity tends to increase due to variance in the thermal expansion coefficient of particles and matrix material [39].…”

“…Hardness is the mechanical property that has the biggest impact on wear [82,83]. To boost the hardness and wear and scuff resistance of Al alloys, many processes, including solid solution strengthening [84], dispersion strengthening [85,86], and precipitation hardening [87,88], can be used. To strengthen a soft matrix by dispersion, hard particles [89] or a combination of hard and soft particles [31,90] might be added.…”
