Abstract：
|
|
Study on semisolid alloy of ZL101 was carried out,which combined the good feature of semisolid ZL101 and micro-forming to discuss the fluidity of micro-formability of semi-solid ZL101 alloy.The analysis and comparison of three important parameters of temperture,extrusion diameter and die bearing for the influence of metal fluidity were made.The results show that semi-solid forming under the micro-forming condition can significantly reduce the extrusion load;a phenomenon which is similar to scale effect happens during semi-solid micro-forming process;die bearing is smaller and extrusion length is longer.
