· JVASP-37055· Ti2AlFe

Ti2AlFe is an intermetallic compound in the titanium-aluminum-iron system, representing a hard, brittle phase that forms in titanium alloys during solidification and high-temperature service. This material is not typically used as a primary structural phase but rather appears as a constituent in multi-phase titanium alloys where it influences overall mechanical behavior, creep resistance, and high-temperature stability. Engineers encounter Ti2AlFe primarily as a strengthening or embrittling phase in advanced titanium alloys designed for aerospace and power generation applications, where understanding and controlling its formation is critical to achieving desired combinations of strength and toughness.
