Overview

This research investigates thermodynamic properties and phase stability in Al-Zn-Cu alloys, indicating how mechanical alloying enhances structural outcomes.

Key Points

  • Phase stability and enthalpy calculations reveal that Al-Zn-Cu alloys achieve maximum stability in specific compositions, indicating their potential for applications.
  • The study finds a mechanical alloying process leads to a consistent average particle size of about 33 nm, aligning with theoretical expectations for structural integrity.
  • Thermodynamic analysis demonstrates negative enthalpy values in Cu-Al and Cu-Zn systems signify favorable conditions for alloy formation and stability, essential for engineering applications.
  • Field Emission Scanning Electron Microscopy identifies nanoparticles' agglomeration and irregular shapes, demonstrating enhancements in hardness and wear resistance.
