Nanoparticle-induced unusual melting and solidification behaviours of metals [PDF]
Nature Communications, 2017 A material with a deep melted zone (MZ) but small heat-affected zone (HAZ) is ideal for manufacturing, but improving one zone comes at the expense of the other.

Dependence of Solidification for Bi2Te3−xSex Alloys on Their Liquid States
Scientific Reports, 2017 The resistivity versus temperature (ρ-T) behaviours of liquid n-type Bi2Te3−x Se x (x = 0.3, 0.45 and 0.6) alloys are explored up to 1050 °C. A clear hump is observed on all ρ-T curves of the three studied Bi2Te3−x Se x melts during the heating process ...

Colour Metallography of Cast Iron [PDF]
China Foundry, 2009 Cast iron, as a traditional metal material, has advantages of low total cost, good castability and machinability, good wear resistance and low notch sensitivity, and is still facing tough challenge in quality, property and variety of types etc.

The rainfall effect onto solidification and stabilization of heavy metal-polluted sediments [PDF]
Royal Society Open Science, 2020 Rainfall makes impacts on the process of solidification/stabilization (S/S) and the long-term safety of solidified matrix. In this study, the effect of rainfall on solidification/stabilization process was investigated by the rainfall test. The unconfined

Settling of inertial particles in turbulent Rayleigh-Bénard convection [PDF]
Physical Review Fluids, 2020 The settling behaviour of small inertial particles in turbulent convection is a fundamental problem across several disciplines, from geophysics to metallurgy. In a geophysical context, the settling of dense crystals controls the mode of solidification of
