Hot deformation and softening response for the titanium aluminide Ti–48Al–2V–0.2B has been investigated. The to mechanisms examined. Deformation experiments were carried out in strain rate range 0.01–10 s?1 keeping temperature constant at 1200 °C 1000–1200 1 s?1. With an increase rate, microstructural changes associated with mechanism include breaking of lamellae, spheroidization broken laths d...

The Al80Mg5Li5Zn5Cu5 light-weight high-entropy alloy with globular microstructure was fabricated by isothermal heat treatment. effects of temperatures and holding times on the semi-solid evolution were investigated. results indicate that, increase temperature, average grain size increases spheroidization time shortens. With prolongation time, shape factor firstly then decreases, decreases at fi...

Highly porous, ferromagnetic glass-ceramic P40-Fe3O4 microspheres (125–212 µm) with enhanced cytocompatibility have been manufactured for the first time via a facile, rapid, single-stage flame spheroidization process. Dispersions of Fe3O4 and Ca2Fe2O5 domains (≈10 embedded within P40 (40P2O5-16CaO-24MgO-20Na2O in mol%) phosphate-based glass matrices show evidence remanent magnetization (0.2 Am2...
