中文摘要 | 本研究利用機械合金法製備了一系列合金,從二元合金至多元高熵合金,並研究過程中的合金化行為,發現了在機械合金過程中,組成元素是以一種特別的順序合金化;而藉由比較各元素的基本性質,我們提出影響合金化順序的主要因子是元素的熔點。此外,我們在機械合金過程中,亦發現了兩種非晶質化類型,而決定非晶質化類型的主要因子是原子尺寸和鍵結強度。 |
英文摘要 | In this research, we prepared a series of alloys from binary to high-entropy alloys by mechanical alloying. The alloying behavior of these alloys has been investigated. We have found that the constituent elements alloy with each other in a specific sequence during mechanical alloying. By comparing the fundamental properties of each element, we propose that the dominant factor of the alloying sequence is the melting point. In addition, two different amorphization types during mechanical alloying were identified. The main factors determining the amorphization type are atomic size and bonding energy. |
