Melting of Aluminum Surfaces

The thermal disordering of Al(110) and Al(111) surfaces was studied up to temperatures of 0.5 and 1.2K below the bulk melting point Tm, respectively. With the use of medium energy ion scattering, it was found that surface melting is present on the (110) face but not on the (111) face. The (110) diso...

Summary:The thermal disordering of Al(110) and Al(111) surfaces was studied up to temperatures of 0.5 and 1.2K below the bulk melting point Tm, respectively. With the use of medium energy ion scattering, it was found that surface melting is present on the (110) face but not on the (111) face. The (110) disordered layer thickness increases with temperature as ln (Tm/(Tm--T)). The results are discussed in terms of a thermodynamic model that was presented earlier to explain the melting of Pb surfaces. Graphs. 36 ref.--AA(UK/US).
