THE ICOSAHEDRAL Al-Li-Cu PHASE

STRUCTURE OF STABLE INTERMETALLIC COMPOUNDS OF THE Al-Li-Cu-(Mg) AND Al-Li-Zn-(Cu) SYSTEMS

The results of a thorough structural study of crystalline intermetallic compounds within the Al-Li-(Cu,Mg,Zn) system are given. Characteristic morphologies of these ternary or quaternary phases are exhibited by concentrated alloys or large single crystals. Typical X-ray powder diffraction data, selected area electron diffraction patterns and high resolution electron microscopy images are shown,...

CASTABILITY OF Al-Li-Mg AND Al-Li-Cu-Mg ALLOYS

The objective of the present work is to study the casting characteristics of various A1-Li alloys, which include fluidity and strengths of the alloys and their interaction with cast molds. Materials investigated are Al-Li-Mg and Al-Li-Cu-Mg alloys with Li content of 2.5 wt%. The results show that sand molds with resin binders are good for A1-Li casting. Ceramic coatings can further reduce the m...

First-Principles Calculation of the Cu-Li Phase Diagram

Abstact We present first-principles calculations of the solid-state portion of the Cu-Li phase diagram based on the cluster expansion formalism coupled with the use of (i) bond length-dependent transferable force constants and lattice dynamics calculations to model of vibrational disorder and (ii) lattice gas Monte Carlo simulations to model configurational disorder. These calculations help set...
