The phase composition and microstructure of Sr-hexaferrite (SFO) ceramics govern the hard magnetic properties. Here, pressureless spark plasma sintering (pSPS) technique was employed for the rapid consolidation (500°C/min) of SFO in a radiating graphite crucible under vacuum and, thus, reductive con ...

In this study, the effect of adding calcium or strontium to Al-Mn and Al-Mn-Cu alloys on the formation of quasicrystals (QCs) is investigated. The alloys were cast in a massive copper mould with a cavity diameter of 3 mm. The cast alloys were characterised by X-ray diffraction, scanning electron mic ...

Medium- and high-entropy alloys (MEAs and HEAs) are the basis of unique electrocatalysts for hydrogen-evolution reactions (HERs) due to their tunable chemical compositions and microstructures. Here, various Cantor MEAs (CoFeNi, CoFeNiMn, CoFeNiCr) and a HEA (CoFeNiMnCr) made up of affordable non-nob ...
