Dynamic Recovery and Recrystallization During Hot-Working in an Advanced TiAl Alloy Dynamische Erholung und Rekristallisation während der Warmverformung in einer TiAl-Hochleistungslegierung
Intermetallic TiAl alloys are light-weight high-temperature materials and intended to partly replace Ni based alloys in jet engines. Due to difficult forming operations, component prices are high and limit the possible field of application. During hotworking, recovery and recrystallization effects determine the microstructural evolution and thereby the mechanical properties of the finished part...
متن کاملAtomic Scale Chemistry of α2/γ Interfaces in a Multi-Component TiAl Alloy
We report on the distribution of micro-alloying elements in a multi-component TiAl-based alloy. The specimen contains 3 at.% Nb, 1.5 at.% Cr, 0.5 at.% Mn, 0.6 at.% (W + Hf + Zr), and 0.2 at.% each of B, C, and O. The distributions of all micro-alloying elements with respect to the heterophase interface between α2 and γ lamellae are analyzed with a three-dimensional atom-probe (3DAP) microscope....
متن کاملHot Deformation Behavior and Pulse Current Auxiliary Isothermal Forging of Hot Pressing Sintering TiAl Based Alloys
This paper focuses on the fabrication of as-forged Ti46.5Al2Cr1.8Nb-(W, B) alloy via pulse current auxiliary isothermal forging (PCIF). The starting material composed of near gamma (NG) microstructure was fabricated by adopting pre-alloyed powders via hot pressing sintering (HPS) at 1300 °C. Isothermal compression tests were conducted at a strain rate range of 0.001-0.1 s-1 and a temperature ra...
متن کاملStudying the Effect of Productive Factors on Synthesis of Anostructure Tial (Γ) Alloy By Mechanical Alloying
In this research, the Planetary mill was used for mechanical alloying (MA) of Ti and Alpowder mixture with equal at% (Ti50Al50). The effect of various factors, such as process control agent(PCA), speed of rotation of vial and ball-to-powder weight ratio, on process were studied and the bestcondition to synthesis the alloy was determined. Study on X-ray diffraction (XRD) patterns showedthat at p...
متن کاملAn in-situ high-energy X-ray diffraction study on the hot-deformation behavior of a b-phase containing TiAl alloy
In engineering materials, microstructural evolution during hot-working critically determines the properties of the finished part. Intermetallic TiAl alloys are no exception and numerous attempts have been made to improve their performance by subjecting them to harmonized hot-working steps. In the current work a novel in-situ diffraction technique along with conventional microscopic methods were...
