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 ...

Assessment of solidification behaviour of peritectic steels [PDF]
, 2018 Casting of peritectic steels is often associated with defects such as cracking that may lead to breakouts. Such defects have technical and financial disadvantages. There are many arguments about the reason for the defect formation in peritectic steels. The principal purpose of the present research is to gain a further understanding for the cause of the

Solidification and flow behaviour of mould fluxes
Mould fluxes are synthetic slags added to the molten steel surface in the copper mould and provide lubrication by melting and infiltrating the gap between the solidified steel and mold. The use of mould lubricants in continuous casting of steel has been an important operational measure since the inception of continuous casting as early as the 1940's ...

Rapid solidification behaviour of Fe and Al based alloys
, 2009 Rapid solidification experiment on Fe-Cr-Mo-Mn-Si-C alloy was performed to investigate metastable phases formed during the solidification. A wide range of cooling rate was used to analyse the sample from melt spinning technique (~107 K/s) to water quenching method (~102 K/s).

Extinction behaviour for two–dimensional inward-solidification problems [PDF]
Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2003 Summary: The problem of the inward solidification of a two-dimensional region of fluid is considered, it being assumed that the liquid is initially at its fusion temperature and that heat flows by conduction only. The resulting one-phase Stefan problem is reformulated using the Baiocchi transform and is examined using matched asymptotic expansions ...
