| titleOfInvention | Method for preparing semisolid blank |
| abstract | The invention relates to a method for preparing a semisolid blank, utilizes an improved SIMA (strain induced melt activation) method to prepare the semisolid blank, and belongs to the technical field of metal semisolid blank. The method comprises the following steps of: firstly, measuring a liquid solid phase line point of the semisolid alloy to be prepared, then, heating an alloy blank so as to carry out asynchronization multitrack rolling or pillar squeezing transformation, finally, remelting, and carrying out heat preservation for a long time so as to obtain the required semisolid blank. The asynchronization rolling or pillar squeezing transformation is capable of generating large deformation amount, group bough crystal formed in the blank is destroyed, the asynchronization rolling is utilized to replace pre-deformation processes such as the existing upset, compression, equal diameter angle compression, and the semisolid blank is prepared and has the advantages of uniform formation, high nodularity, and accurate control solid phase rate. |
