“…However, there is greater interest in forming the carbide particles in-situ from elemental titanium and graphite. This would increase cost-effectiveness, as well as create finer particle distribution and the desired carbide-matrix interface characteristics [7,29,30]. TiC has been previously synthesized in-situ during laser cladding processes from powdered titanium and graphite in matrices of nickel [31], chromium [32], iron-aluminium [33], ␥-NiCrAlTi [9], and cobalt (on a mild steel substrate) [34].…”

“…These superiorities make them potential candidates in the same way as CFMMCs for critical applications in the aerospace and automotive industries. Typical uses of discontinuous or particle titanium composites include creep resistant engineering components, wear parts such as gears, bearings, shafts and erosion-corrosion resistant tubing [7].…”

The purpose of this work is to investigate the cyclic plasticity and creep-cyclic plasticity behaviours of particle reinforced titanium matrix composites (PRTMCs) SiC/Ti-6242, aimed to be used in high temperature applications. The investigation has been conducted upon microstructures that have been taken from a previous study where low-fidelity model-based optimization (LFMBO) has been used to maximise the elastic behaviour of particle reinforced aluminium matrix composites. The effect of the particle spatial distribution, particle fraction volume and number of particles on the shakedown limit, limit load and creep-cyclic plasticity have been explored by direct numerical techniques based on the Linear Matching Method (LMM) framework. The micromechanical approach to modelling and fifteen multi-particle unit cells have been investigated. Under cyclic loading conditions, the structural response of PRTMCs is not trivial and becomes even more significant when high temperature is involved. Hence, the factors that affect the creep and cyclic plasticity of PRTMCs are analysed and discussed, including effects of the applied load level, dwell period and temperature on the composites' performance. The applicability and accuracy of the proposed direct method has also been verified by the step-by-step analysis.

“…The in situ synthesis technology constitutes one of the most promising approaches towards fabricating the particulate-reinforced titanium-based composite with mechanical properties elevated by the hard phases formed in situ [7][8][9]. It is well known that there are reaction paths between Ti and B 4 C, which result in the formation of TiB, TiB 2 , and TiC.…”

High specific modulus materials are considered excellent for the aerospace industry. The system Ti-TiAl-B 4 C is presented herein as an alternative material. Secondary phases formed in situ during fabrication vary depending on the processing conditions and composition of the starting materials. The final behaviors of these materials are therefore difficult to predict. This research focuses on the study of the system Ti-TiAl-B 4 C, whereby relations between microstructure and properties can be predicted in terms of the processing parameters of the titanium matrix composites (TMCs). The powder metallurgy technique employed to fabricate the TMCs was that of inductive hot pressing (iHP) since it offers versatility and flexibility. The short processing time employed (5 min) was set in order to test the temperature as a major factor of influence in the secondary reactions. The pressure was also varied. In order to perform this research, not only were X-Ray Diffraction (XRD) analyses performed, but also microstructural characterization through Scanning Electron Microscopy (SEM). Significant results showed that there was an inflection temperature from which the trend to form secondary compounds depended on the starting material used. Hence, the addition of TiAl as an elementary blend or as prealloyed powder played a significant role in the final behavior of the TMCs fabricated, where the prealloyed TiAl provides a better precursor of the formation of the reinforcement phases from 1100 • C regardless of the pressure.
