Paper Title:
Synthesis and Mechanical Properties of Conventionally Cast Icosahedral Particle-Reinforced Al-Mn(-Cu)-Be-Si Alloys
  Abstract

The microstructure of the Al-Mn(-Cu)-Be-Si alloys analyzed by X-ray diffraction and TEM consisted of icosahedral (i) quasicrystal particles embedded in aAl matrix. The conjoint addition of Si and Be elements enabled the i-phase formation in Æ10 mm specimens prepared by conventional casting technique. The size, volume fraction and stability of the i-phase were found to be dependent on the Mn content. The addition of 2 at.% Cu did not affect the formation and stability of the i-phase but contributed significantly to the enhancement of the mechanical properties.
