Abstract

See full text

A production method of an extrusion billet includes a step of preparing a plate or lump starting material comprising a magnesium alloy, a step of performing a plastic deformation process at a rolling reduction of 70% or more to the starting material at a temperature of 250° C. or lower to introduce a strain without generating dynamic recrystallization, a step of producing powder by granulating the material after the plastic deformation process, and a step of producing a powder billet by compressing the powder.
