The ICME ( Integrated Computational Materials Engineering) for aluminum alloys was applied to combine key experiments with multi-scale numerical simulations from nano ( 10 -10-10 -8 m ) to micro ( 10 -8-10 -4 m ) to meso ( 10 -4-10 -2 m ) and to macro (10 -2-10 m) during the whole R&D (research and development) process of aluminum alloys. Using integrated analysis of the compo-sition-processing-structure-properties, the methodology for developing aluminum alloys was promoted from trial and error to scientific design, SO the R & D of aluminum alloys was significantly speed up and the cost was reduced. In this paper, multi-scale simulation approaches including Ab-initio, CALPHAD (CALculation of PHAse Diagram), phase field, and finite element method together with experimental methods characterizing structure and properties are elaborated. The function of each method in the R&D of aluminum al-loys is carefully discussed. Based on ICME, the framework for R&D of aluminum alloys, involving end-user demand, product design and industrial design, is established. Two application examples are presented to describe the important role of ICME during the devel-opment stage of aluminum alloys, which provides an innovative pattern for R & D of advanced aluminum alloys.
