Microstructure Characterization of SUS444 Ferritic Stainless Steel
… sample was due to the precipitation of fine Laves phases which pinned down the motion of dislocations. As deformation progressed the strength increased until a critical precipitate size, volume fraction and dislocation density before Laves phases begun to rapidly coarsen and resulted in the …

Lightweight Intermetallics with Laves Structures as Potential Hydrogen Storage Materials
… requirements. Intermetallic compounds with Laves structures in the formula of AB2 have long been known to store hydrogen in their interstitial sites to serve as reversible hydrogen storage materials (A and B are metallic elements). They have the potential to be hydrided to a maximum of ~ …

Multi-component ab2 metal hydride alloys for nickel metal hydride battery applications
… nature, which includes the main C14/C15 Laves phases and the secondary non-Laves phases.</p> <p>In order to optimize the gaseous phase and electrochemical advantages of both the C14 and C15 Laves phases, a study was established to recognize the factors that affect the C14/C15 phase …

Navigating the Intermetallic Landscape: From Quasicrystal Approximants to High Pressure Crystal Chemistry
… including Zintl-like structures, Frank-Kasper phases, interstitial Mn5Si3-type structures, classical Laves phases, and a decagonal quasicrystal approximant. Their formation and bonding is understood through comprehensive analysis of their electronic structure using density functional theory. …

Novel integrated computational approach for designing Fe-Ni-based alloys
… properties of the alloy by forming coarse Laves phases on the grain boundaries. Therefore, the alloy sheet, with the same composition of Fe-opt but without W (Fe-opt2) was prepared and examined. Fe-opt2 has higher strength than Fe-opt and than more expensive Ni-based superalloys, such as …

Compositional Exploration and Microstructural- Environmental Evaluation of Alloys for Glass Vitrification Applications
… at 800°C and 1200°C through oxidation-induced Laves phase formation and the development of continuous silica scales, albeit at the expense of room-temperature ductility. Ta additions promoted MC carbide formation and, at the highest concentration, replaced the Cr-rich M23C6 network with σ and …

Microstructure and mechanical behavior of metastable beta type titanium alloys
… Ti- 33Zr-3Fe-2Cr alloy, demonstrate a C15 type Laves phase and a dominating β phase. Moreover, the Ti-35Zr-5Fe-xMn and Ti-xZr-7Fe-ySn alloys show C14 type Laves and β phases. It is quite interesting to investigate the deformation and strength characteristics of hexagonal close-packed C14 and …

Untersuchungen zur Natur der Laves-Phasen in Systemen der Übergangsmetalle
Laves-Phasen sind intermetallische Verbindungen der Zusammensetzung AB2, die in den Strukturtypen C14 (MgZn2), C15 (MgCu2), C36 (MgNi2) oder deren Abkömmlingen kristallisieren. Diese sind Polytypen mit einem gemeinsamen grundlegenden Strukturmuster. Insgesamt sind über 1400 binäre und ternäre …
