Progress in additive manufacturing on new materials: A review
TL;DR: In this article, a review of recent efforts and advances in additive manufacturing (AM) on different types of new materials is presented and reviewed, focusing on the material design of cladding layers, the choice of feedstock materials, the metallurgical behavior and synthesis principle during the AM process, and the resulted microstructures and properties, as well as the relationship between these factors.

Electron beam melting of Ti–48Al–2Cr–2Nb alloy: Microstructure and mechanical properties investigation
Sara Biamino,Andrea Penna,Ulf Ackelid,Silvia Sabbadini,O. Tassa,Paolo Fino,Matteo Pavese,P. Gennaro,Claudio Francesco Badini +8 more
TL;DR: In this article, electron beam melting (EBM) is used to realize a selective densification of metal powder by melting it in a layerwise manner following a CAD design, and microstructure, the residual porosity and the chemical composition of the samples have been investigated both immediately after EBM and after heat treatments.

Ordered intermetallic alloys, part III: Gamma titanium aluminides
TL;DR: In this paper, an improved understanding of both fundamental and practical aspects of these aluminides, such as phase relations, microstructure evolution and control, processing, micro-structure-property relationships, and deformation and fracture processes, is presented.
Journal ArticleDOI
Fabrication of TiAl components by means of hot forging and machining
TL;DR: In this article, a new Ti-42Al-5Mn (at.%) alloy was developed, which features capabilities for hot forging and machining, and in this study hot forging was performed from an industrial perspective and it was ascertained that the objective components could be fabricated using this new alloy.
Journal ArticleDOI
Effect of boron addition on tensile ductility in lamellar TiAl alloys
TL;DR: In this article, it has been found that titanium boride precipitates are the predominant factor influencing the room temperature tensile ductility of cast or wrought fully lamellar TiAl-based alloys with and without boron addition.

Phase equilibria and transformations in intermediate titaniumaluminum alloys
S.A. Jones,Michael J. Kaufman +1 more
TL;DR: The phase equilibria and solid state phase transformations observed in Ti-Al alloys between 40 and 50 at.% Al are reported in this paper, where it is shown that the three-phase invariant between the high temperature α phase (disordered h.c.p.) and the lower temperature ordered α2-Ti3Al (D019) and γ-TiAl (L10) phases is eutectoid in nature (α → α2 + γ) but that it is difficult to produce this reaction experimentally due to differences in the

Phase transformation mechanisms involved in two-phase TiAl-based alloys-II. Discontinuous coarsening and massive-type transformation
Anne Denquin,S. Naka +1 more
TL;DR: In this paper, the authors examined the mechanisms involved in two of the three major transformation modes appearing in two-phase TiAl-based alloys: discontinuous coarsening and massive-type transformation.
