Microstructure Evolution and Mechanical Properties of FeCoCrNiCuTi0.8 High-Entropy Alloy Prepared by Directional Solidification [PDF]

open access: yesEntropy, 2020
A CoCrCuFeNiTi0.8 high-entropy alloy was prepared using directional solidification techniques at different withdrawal rates (50 μm/s, 100 μm/s, 500 μm/s). The results showed that the microstructure was dendritic at all withdrawal rates. As the withdrawal

Directional Solidification of Ledeburite [PDF]

open access: yesArchives of Foundry Engineering, 2013
Abstract Directional solidification of ledeburite was realised out using a Bridgman’s device. The growth rate for movement sample v=83.3 μm/s was used. In one sample the solidification front was freezing. The value of temperature gradient in liquid at the solidification front was determined.

Influence of gases on casting expansion processes during their hardening

open access: yesЛитьë и металлургия, 2023
It has been experimentally shown that directional solidification of water and bismuth in glass and quartz cylindrical forms does not result in expansion of the castings perpendicular to the solidification direction.

Transition to chaos in directional solidification [PDF]

open access: yesPhysical Review Letters, 1991
Summary: Interface dynamics are analyzed theoretically in the quasilocal regime of directional growth explored by experiments on liquid crystals. We discover ``vacillating-breathing'' (VB) modes. Upon variation of the growth speed the interface motion enters a chaotic regime via a quasiperiodicity scenario.
