| Summary: | 碩士 === 中華大學 === 機械與航太工程研究所 === 92 === The eutectoid alloy is one of the oldest superplastic alloys. Through a suitable heat treatment, the Zn-22Al eutectoid alloy will change to a very fine-grained duplex structure. On the other hand, forging and extrusion are very important bulk deformation processes, using compressive forces to manufacture complex-shaped components.
Zn-22Al eutectoid Alloy Micro-channel uses the Heat Embossing System HEX 01/sp in the search for the suitable process variable. Under different depth / length ratios, tension rate and tension load, the comparative results after experiment analysis found that under a tension load of 5000N、7000 N、10000 N and a tension rate of 0.06 mm/min, the model filling of the channel. After Zn-22Al eutectoid Alloy Micro-channel would be bonding.The results indicated that the fine-grained Zn-22Al eutectoid alloy possessed excellent formability.
