Journal ArticleDOI
Solidification microstructure selection of the peritectic Nd-Fe-B alloys
TL;DR: In this paper, a solidification microstructure selection map was established, based on the consideration of solidification characteristics of peritectic T1 phase, with the increasing growth velocities.
Journal ArticleDOI
Refined dendrite and precise orientation of nickel-based monocrystal superalloy with melt superheating treatment
TL;DR: In this article, the melt superheating treatment is carried out for DD3 single crystal superalloy during directional solidification processing, and the dendrite segregation ratios of Mo, W and Ti are reduced while deviation angle of (001) crystal orientation can all be controlled within 5°.
Journal ArticleDOI
TEM investigations on twin boundary structures of feathery crystals in aluminum alloys during Bridgman solidification
TL;DR: In this article, the high-density twinned dendrites of Al-4.5wt% Cu alloys, produced during the Bridgman solidification, have been studied using electron backscattered diffraction and high-resolution transmission electron microscopy (HRTEM).
Journal ArticleDOI
Ordering Transformation and Age Hardening in a Ni-Cr-W Superalloy
TL;DR: In this article, the microstructural changes occurring in a Ni-Cr-W superalloy during prolonged exposure to proper temperature have been investigated using transmission electron microscopy, and the mechanism of transformation to long-range order has been revealed to accord with continuous mode based on transmission electron microscope results and variation trend in Vickers microhardness.
Journal ArticleDOI
Influences of travelling magnetic field on the dendritic structures of Sn-1.8Cd peritectic alloy during directional solidification
TL;DR: In this paper, the effects of melt flow driven by a travelling magnetic field (TMF) on solidification structures of Sn-1.8-wt. peritectic alloy have been investigated numerically and experimentally.
