The Mechanical Properties Improvement of FeAl Intermetallic Comp ound with Rare Earth Elements.
碩士 === 國立臺灣大學 === 材料科學(工程)研究所 === 81 === FeAl為B2型的介金屬化合物,具有優良的高溫強度,比重輕,優良的抗氧 化性及耐腐蝕能力及材料成本低等優點,但低延展性及脆性破裂等問題卻 是FeAl介金屬所急欲改善的。文獻中有許多學者有關研究B2型的FeAl之報 導(鋁含量35-50at%),當鋁含量愈高時,晶界愈脆弱,沿晶破裂嚴重, 延展性極差;當鐵含量高時,比重增加,降低其高溫本抗氧化能力,故實...
