Al、Fe、Cr元素對Femealloy及鑄材結構及機械性質影響
The Effects of Al, Fe, Cr Addition on the Structure and Mechanical Property of Femealloy
摘要
本論文主要在探討5-6元之femealloy（Function Enhanced Multi-Element Alloy：多元高性能合金）設計及製程技術，突破傳統的合金以單一元素為主的設計觀念，本研究主要是以Fe、Ni、Si、Cr、Al、Co為主之6元多元合金（各主元素含量約在5-35%原子比）探討其元素對femealloy影響。 實驗分析主要以MTS拉伸試驗機測試各試片抗拉強度及伸長率；以高溫DSC-2000熱分析儀進行熔點與可能的高溫相變化分析；且利用MATSUZAWA SEIKI MV-1維式硬度機量測硬度值；晶體結構採用X-ray繞射儀來進行晶體結構分析。 探討Al、Fe、Cr含量變化對多元高性能合金鑄材在機械性質上差異影響，進而建立多元高功能合金設計、改善熔鑄等技術，期望將多元高性能合金用來當作需要高強度、耐磨、耐溫、耐蝕之工具、模具、機件等用途另外選擇的新一代合金材料。

This work reports the design and preparation processes of 5-6 element Femealloy (Function Enhanced Multi-Element Alloy). The conceptual idea is somehow different from design and preparation of traditional alloy. In this paper, the Femealloy contains 6 components (i.e. Fe, Ni, Si, Cr, Al, Co), varying the element compositional ratio (atm %), can affect the physical property of Femealloy. The tensile strength and elongation property was characterized by MTS stretch testing machine. The melting point and phase transformation was detected by using high temperature DSC-2000 thermal analysis meter. The hardness and crystal structure of Femealloy was measured by MATSUZAWA SEIKI MV-1 and X-ray diffraction instrument respectively. The physical properties of Femealloy can be tuned by controlling the Al, Fe and Cr elemental content ratio. The structural modification of material may play a crucial role in the design and casting improvement of Femealloy. The Femealloy can be potentially used as high strength, high wear and temperature resistance material in tooling and molding machines.
