The fluidity of Mg–Al specimen has been investigated in order to establish semi-solid press-forming technology. The fluidity of strain-introduced specimen is much better than that of non-strained specimen leading to the microstructure with uniformly-distributed spherical particles. Fluidity during semi-solid press-forming of strain-introduced bulk increases with increase in the die temperature. But when injection speed is too high, porosity is easily generated because air bubbles are trapped into the specimen due to turbulent flow of semi-solid specimen. Too large particles gather in step section of die, resulting in the segregation of liquid phase.
