High entropy alloys (HEAs) are unique and novel materials with remarkable properties that render themcompetitive for developing key engineering applications within modern engineering sectors. In the present study,a AlCoCrFeNi HEA was gas tungsten arc welded to 316 L stainless steel, with the aim of assessing the compatibilityin terms of microstructure and mechanical performance. [...]

The transformation of retained austenite under mechanical load has a significant impact on the mechanicalproperties of high-strength low-alloy steels and weld metals. Here, we have studied the stability of retainedaustenite in a microalloyed, multipass high-strength all-weld metal using in situ high-energy X-ray diffractionphase quantification during tensile loading. [...]

This study investigated the microstructure, tensile strength, wettability, and steam oxidation resistance of as-castIN713C fabricated by vacuum lost-wax casting. A comprehensive array of techniques, including thermodynamicsimulations, synchrotron X-ray diffraction, differential thermal analysis, optical and electron microscopy, tensiletesting, sessile drop testing, and a high-temperature oxidation experiment, was employed to characterize the ascastmicrostructure. [...]

Dissimilar fusion welding between NiTi shape memory alloy and AlCoCrFeNi2.1, eutectic high entropy alloy wasachieved using a combination of Nb and Cu interlayers. Both base metals exhibit unique properties that complementeach other making them attractive for integration in smart systems. [...]

High-throughput X-ray diffraction (XRD) techniques are revolutionizing materials science by enabling the rapid collection ofhundreds or thousands of diffraction patterns in a single experiment. However, traditional analytical methods like Rietveld refinementbecome a significant bottleneck for quantifying phase fractions from such large datasets, due to their time-consuming,expert-driven nature. [...]

Understanding the nature of active sites in heterogeneous catalysts and how to create them purposefully opens up the possibility of tailored catalyst design. Here we report mixed-valence subnanometre CoOx clusters, consisting of a few metallic Co⁰ atoms on top of Co²⁺, bound to a silicalite-1 support through lattice oxygen atoms as active species for non-oxidative propane dehydrogenation (PDH) to propene.
