Abstract (en)
[origin: EP3486340A1] The present invention provides an aluminum alloy plastic working material which has a low Young's modulus, but has superior proof stress, and a method for efficiently producing the aluminum alloy plastic working material. The aluminum alloy plastic working material according to the present invention contains 5.0-10.0 wt% of Ca, the balance being aluminum and incidental impurities, and has 25% or more by volume of an Al 4 Ca phase which is a dispersed phase. The Al 4 Ca phase comprises a tetragonal Al 4 Ca phase and a monoclinic Al 4 Ca phase, and the intensity ratio (I1/I2) of the highest diffraction peak (I1) attributed to the tetragonal system to the highest diffraction peak (I2) attributed to the monoclinic system, which are obtained by an X-ray diffraction measurement, is one or less.
