Title:
【発明の名称】段階的ミクロ組織から成る多領域を有したγ‐TiAl合金を主成分とする物質
Document Type and Number:
Japanese Patent JP2003533594
Kind Code:
A
Abstract:
The invention relates to a component produced in one piece from an intermetallic gamma-TiAl-based alloy with graduated microstructure transition between spatially adjacent areas each of different microstructure structure, which has a lamellar cast microstructure composed of alpha2/gamma lamellae in at least one area, and a near-gamma microstructure, duplex microstructure or fine-lamellar microstructure in at least one other area, and a transition zone with graduated microstructure, in which the lamellar cast microstructure gradually changes into the other named microstructure, is present between these areas, as well as to a process for its production.
