“…High oxidative weight gain is mainly related to the oxidation time and the reaction speed. According to the oxidation theory of Wagner, 19 the relationship between the oxidative weight gain and the oxidation time of a material can be expressed by equation (2).…”

“…There is a growing interest in Titanium matrix composites (TMCs) because of their specific high strength, high modulus, and excellent wear, especially at elevated temperatures. 1,2 These properties make them desirable for use in the aircraft industry, particularly in the compressor section design for weight reduction caused by superalloys of nickel. 3 TMCs are prepared by directly adding reinforcing phases such as particles, whiskers, and fibers to the titanium alloy matrix or by generating in-situ reactions to produce the reinforcing phases.…”

This study used SiCp, SiCw, B4C, and GPLs as reinforcements for Ti750 matrix alloy and composites synthesized by spark plasma sintering. The oxidation performances of the composites were then evaluated at 800 °C. 5 vol.% SiCp reinforced Ti750 composite recorded the least oxidation weight gain of 3.80 mg.cm−2, about 41.8% of the base alloy. The average oxidation rates K + of the five materials at 800 °C were less than 1 g.m−2.h−1, indicating all materials were within the anti-oxidation grade with excellent anti-oxidation performance. The oxidation products of the samples contained TiO2, Al2O3, and SiO2. 5 vol.% SiCp reinforced Ti750 composite had significantly flatter and denser oxide film, which was well bonded with the matrix thus having a better protective effect than the matrix material. With the addition of SiCp, the thickness of the oxide film decreased, and the resistance of the material significantly improved its high-temperature oxidation performance.

“…TiC particle-reinforced TMCs (TiC-TMCs) have been reported extensively, since TiC particles possess the excellent balance of stability, stiffness, modulus and compatibility with Ti matrices [4][5][6][7]. In the past few decades, in situ synthesized technique and traditional casting has been combined to produce TMCs owing to its obvious advantages such as simplicity, low cost, direct casting forming and large-scale production [8][9][10][11][12].…”

In the present paper, new heat treatment was performed on 10 vol.% TiC/Ti-6Al-3Sn-9Zr-1.5Mo composite fabricated by an in situ casting technique. The aim is to obtain fully lamellar structure in matrix, control the lamellar structure quantitatively and understand the variation of the tensile properties of as-cast and heat-treated composites. For as-cast composite, matrix exhibited fully lamellar structure with some extent of basket-weave characteristics, and reinforcement was mainly in fine rod and strip shape. After β heat treatment, matrix microstructure was refined visibly. As the new cooling method was employed, wider α lath in matrix was obtained. The composite with very fine lamellar structure showed better yield strength (YS) in comparison with that with coarse lamellar microstructure below 650 °C. At 700 °C, fine grain strengthening cannot exert effective influence on tensile strength. It is proved that the enhanced YS is mainly ascribed to the refinement of α lath at ambient temperature. The heat-treated composites with wider α lath displayed excellent ductility at ambient temperature. Above 600 °C, the effect of α phase size on tensile elongation was negligible in the heat-treated composites, since matrix was softened.
