Quasi-crystals Studied with Convergent Beam Electron Diffraction

1988 
Chill-cast Al6CuLi3 was studied together with roller-quenched Al4Mn and melt-spun Al7Mn2. With convergent beam electron diffraction it was established that Al6CuLi3 and Al4Mn exhibited a pentagon as the dominant Kikuchi band pattern while Al7Mn2 showed a decagon. The quasi-crystalline m3¯5¯ and the crystalline Im3 structures seem to occur simultaneously.
