| Abstract Scope |
The aim of the present research was to develop a cast metal matrix composite based on the Al–Cu system, reinforced with titanium carbide (TiC) particles. The A201 aluminium–copper alloy is known for its exceptionally high mechanical strength, particularly after T6 or T7 heat treatment. In this study, the A201 alloy was transformed into a composite material containing varying amounts of TiC (up to 5wt%) using the Self-Propagating High-Temperature Synthesis in Bath (SHSB) method.
The research focused on thin-walled castings with wall thicknesses of 3mm and 5mm. Particular attention was given to the role of TiC particles in reducing the hot tearing susceptibility (HTS) of the A201 alloy.
Microstructural evolution, including grain refinement induced by TiC addition, was analyzed using optical microscopy, SEM, EDX and EBSD. In addition, X-ray diffraction (XRD) analysis was carried out up to 300°C to monitor phase fractions, lattice parameter changes, and internal strain variations. |
