High or medium- entropy alloys (HEAs/MEAs) are multi-principal element alloys with equal atomic elemental composition, some of which have shown record-breaking mechanical performance. However, the link between short-range order (SRO) and the exceptional mechanical properties of these alloys has remai...
Elemental segregation to antiphase boundaries in a crept CoNi-based single crystal superalloy We report on the full three-dimensional compositional partitioning among the features of a planar imperfection comprising a superlattice intrinsic stacking fault (SISF) with its leading and trailing partials, as ...
High-entropy alloys, also commonly referred to as multi-principal element alloys (MPEAs), are a class of materials that are currently of interest among the metallurgical community1,2,7,8,9. In the past decade numerous scientific investigations have uncovered remarkable properties exhibited by these...
Transition metal nitrides are now the subject of numerous studies on introducing cost-efficient alternatives to replace group VIII noble metals in diverse reactions. Their electrocatalytic activity is similar to that of the precious metals without presenting their demerits, e.g., susceptibility to poi...
However, the problem still remains unknown when both solute and solvent atoms are transition metals. In 1964, the PHACOMP (PHAse COMPutation) method [1,2] was developed in the United States. This aimed to predict the solid solubility limit of elements in the Ni (γ) matrix and to avoid ...
constituents as the alloy to be obtained is first melted in the melting container and the component elemental metals of the alloy are thereafter incorporated in the molten material in such a manner as to substantially prevent direct contact between the component elemental metals and the container ...
1. A method for forming carefully controlled compositions of TiNi-base alloys composed of metals reactive in their elemental form with a graphite crucible, comprising the steps of placing into the graphite crucible a prealloyed material of the alloy type to be obtained, heating by external ...
Magnesium alloys are mixtures of magnesium with other metals, often Al, Zn, Mn, Si, Cu, rare earths and zirconium. The Mg alloys has excellent stiffness and strength-to-weight ratio with good e... NS Nithin,H Venkit - 《International Journal of Engineering Trends & Technology》 被引量: ...
elemental mapping (Supplementary Fig.7); however, the presence of oxygen is limited to the surface of the NP (~5 nm thick). The oxide layers might have been formed upon exposure to air. EDX line scans of individual particles for each HEA sample are presented in Fig.3g, h, which ...
Its density of 1.74 g/cm3 means that a weight reduction of up to 25% is possible in comparison to aluminium. Especially, the reduction of car weight is based on such lightweight materials as plastics, but light metals such aluminium or magnesium are easier to machine and superior to ...
