During the solidification of hypoeutectic Al–7% Si alloy, density differences develop in melt due to variations concentration and temperature. On Earth, flow can occur gravity, which then affects process. The microgravity environment strongly eliminates convection allows investigation process purely diffusive circumstances. In this study, four experiments were performed on grain-refined non-gra...

Abstract The manganese-boron alloy 22MnB5 is particularly used for structural and safety-relevant parts in the automotive industry. Parts made from this are usually produced using hot forming process. Here, sheet heated to over 950 °C an industrial roller hearth furnace. then simultaneously formed quenched a cooled tool with temperature gradient of more than 27 K/s. This leads formation martens...

In the present study, a series of AlCoCrxFeNi2.1 (x = 0, 0.25, 0.5, 0.75, 1.0) eutectic high entropy alloys (EHEAs) have been designed and prepared. And effect Cr content on microstructures mechanical properties was systematically investigated. The results indicate that > 0) exhibit almost complete lamellar with mixture structure FCC B2 phases. AlCoFeNi2.1 alloy without element exhibited hypoeu...
