摘要: Abstract In the present work a Calphad type thermodynamic assessment of Al – Li system is presented. The dominated by central AlLi phase, which has an ordered bcc (B32) structure. fcc dissolves considerable amounts Li. If solid solution quenched from high temperature, coherent metastable precipitates with (L1) structure can form. There are two nearly stoichiometric phases; and AlLi. disordered phase as well (Li) described four-sublattice models. fairly complete set experimental data available for this system, most them satisfactorily currently optimised parameters.
