Özet

Multi-pass equal-channel angular pressing (ECAP) was applied to the eutectic Zn-5% Al alloy as a first step in the examination of the binary Zn-Al alloy system by using two different processing routes: route A, where the sample is pressed repetitively through the die without rotation, and route C, where the sample is rotated by 180degrees after each pass. A "three-block die" for ECAP was designed and manufactured. Evolution of hardness was investigated and microstructural changes were noted during ECAP. Variations in the applied load during ECAP of the alloy were analyzed, and the relationship between maximum load and hardness was discussed.
