Overview

Randomized trial evaluates mechanical and wear performance of TiC-reinforced AZ31 composites, indicating threaded pin geometry is most effective.

Key Points

  • This research aims to investigate how different tool geometries affect the microstructure, mechanical properties, and wear performance of TiC-reinforced AZ31 magnesium alloys.
  • Friction stir processing was used to fabricate AZ31 magnesium alloy composites with 10 wt.% TiC using four tool pin geometries: square, hexagonal, tapered, and threaded.
  • Microstructural analysis was conducted to assess grain size, microhardness, and tensile properties.
  • Tribological tests measured wear rates under specific loading conditions.
  • The threaded pin configuration produced the finest grain size at 18.2 µm and the highest microhardness of 113.36 HV.
  • Ultimate tensile strength reached 307.6 MPa with an elongation of 0.105 in the threaded pin composites.
  • Under a 10 N load, the threaded pin composite demonstrated a wear rate of 1.9 × 10−4 g/m, outperforming other geometries.
