摘要: 
本研究先設計11種添加成份、含量不同的多元合金,並將其分為三大系列合金。藉由評估各合金在固溶處理及不同溫度及時間時效後的金相及硬度分析結果,從中挑選析出硬化效果最好的系列合金作為目標合金。並進行拉伸試驗分析,觀察成份及含量的改變對合金的微結構與機械性質的影響。研究結果顯示,多元合金中添加成份的改變會對其微結構及機械性質造成影響,並在某些合金時效後確實能在基地中產生大量的析出物,使合金造成顯著強化且仍保持一定的延性,擁有優良機械性質的合金。

In this research, we designed 11 kinds of multi-compoent alloys with different addition element and contents and divided into three series of alloys. By evaluating the metallographic and hardness analysis results of each alloy after solution treatment and aging at different temperatures and times. We choose the series of alloys with the best hardening effect were the target alloy. Then tensile test analysis was carried out to observe the influence of the change of composition and content on the microstructure and mechanical properties of the alloy. The results show that the change of the added components in the multi-alloy will affect its microstructure and mechanical properties, and some alloys after aging treatment will produce a large amount of precipitates in the matrix, causing the alloy to be significantly strengthened and still maintain a certain ductility, which has excellent mechanical properties.
