Synergistic effects of TC4 content on grain refinement and strengthening mechanisms in TC4 particle-reinforced Mg-8Gd-4Y-1Zn-0.5Zr matrix composites

Key Points

• Improved grain refinement significantly enhances the strength of the Mg-8Gd-4Y-1Zn-0.5Zr matrix composites.
• A 30% increase in tensile strength was noted with the addition of TC4 particles.
• Observational analysis across various composite formulations highlights the role of particle-reinforced mechanisms.
• The findings support the development of stronger, lightweight materials in advanced manufacturing applications.
