Magnesium-based materials, which are known for their light weight and exceptional strength-to-weight ratio, hold immense promise in the biomedical, automotive, aerospace, and military sectors. However, their inherent limitations, including low wear resistance and poor mechanical properties, have driven the development of magnesium-based metal matrix composites (Mg-MMCs). The pivotal role of powder metallurgy (PM) in fabricating Mg-MMCs was explored, enhancing their mechanical and corrosion resistance characteristics.

- - Magnesium (Mg) is gaining interest as a biodegradable material for medical implants due to its good biocompatibility but faces challenges like rapid degradation and low corrosion resistance, which titanium (Ti) can help overcome when alloyed with Mg.
- - The Mg-Ti alloys are created using techniques like mechanical alloying and spark plasma sintering (SPS), leading to improved mechanical properties and corrosion resistance, especially in the Mg80-Ti20 alloy tested in simulated body fluids.
- - These alloys show non-toxicity when tested on pre-osteoblastic cells and can be combined with polymers like PLGA to enhance their biomedical applications, making them suitable for temporary orthopedic implants that support healing without needing removal surgery.
The presented study investigates the effects of weight percentages of boron carbide reinforcement on the wear properties of aluminum alloy composites. Composites were fabricated via ball milling and the hot extrusion process. During the fabrication of composites, BC content was varied (0, 5, and 10 wt.
