The alloy system Al-(Co)-Cr-Fe-Ni contains compositional ranges where a solid state BCC-FCC phase transformation leads to dual-phase materials composed of face-centered cubic (FCC) and body-centered (BCC) phases with nearly equal volume fraction. microstructure arising from this at slow cooling rates is the classical Widmanstätten structure, FCC-laths colonies growing grain boundaries into parent BCC-B2 grain. Very distinct microstructures are obtained, when growth kinetically suppressed...
Refractory-based high entropy alloys (HEAs) of the 2nd-generation type are new intensively-studied materials with a potential for structural high-temperature applications. This paper presents investigation results on microstructural evolution and phase formation in as-cast subsequently heat-treated HEAs at various temperature-time regimes. Microstructural examination was performed by means scanning electron microscopy (SEM) combined energy dispersive spectroscopy (EDS) mode probe...
This paper examines the microstructure and mechanical properties of Ta20Nb20Hf20Zr20Ti20. Two casting processes, namely, gravity suction-assisted casting, were applied, both followed by Hot Isostatic Pressing (HIP). The aim current study was to investigate creep tensile material, since literature review revealed no data whatsoever regarding these properties. main findings are that HIP process is responsible for appearance a Hexagonal Close Packed (HCP) phase dispersed differently in two...
The AlCrFe2Ni2 high entropy alloy exhibits an interesting microstructure, which changes considerably when various thermal treatments are applied. These manifested mostly through the precipitation and dissolution of several BCC FCC phases. To gain better understanding as to phase evolution in with respect history, microstructures four states were investigated using Transmission Electron Microscope (TEM) resolution TEM. included as-cast, homogenized at 1185°C for 75 minutes, aged 750°C 4...
Since the discovery of M7C3-type carbide in 1935, it has been subject many experimental and theoretical studies. Initially, structure was thought as being either trigonal or hexagonal, while later publications indicated that more likely to be orthorhombic. Even today, 8 decades after its discovery, claim M7C3 carbides are hexagonal orthorombic “beyond doubt”, others, acknowledge lack agreement literature try resolve using first principles calculations which rely on atomic positions...
The implementation of additive manufacturing techniques in the production mission critical structural components is challenged by its low throughput, limited build envelope and short list supported alloys. In recent years, academic industrial efforts led to emergence new alloys for powder bed fusion processes, allowing a wider use Additive (AM) technology variety sectors, while leveraging core add-values such as enabled design freedom buy-to-fly ratio. Proving that achievable material...
