Rapid Solidification - Mechanisms, Morphology and Microstructure
MRS Proceedings, 1981The cooling rates that accompany manufacture of gas turbine superalloy powders are sufficient to produce metastable structures and phase distributions. It is the aim of this investigation and report to develop some understanding of the relationships between powder manufacturing processes and powder structures by comparison of material made by two ...

Solidification and Microstructure Characteristics of the AlMg9 alloy
2009Recently, foundry Al-Mg alloys play an important role in overall foundry industry of light metals due to their high strength and ability of precipitation hardening for higher magnesium contents. Influence of the cooling rate on the solidification and microstructure development of AlMg9 alloy have been investigated in this paper.

Modelling of microstructure formation in solidification processes
International Materials Reviews, 1989AbstractModelling of heat flow has become a standard practice in many solidification processes. Effort is currently being made to couple heat flow calculations to related macroscopic phenomena such as mould filling, fluid flow, macrosegregation, or thermal stresses.

The application of microstructure-selection maps to droplet solidification
1997The techniques of electromagnetic levitation, drop-tube processing and atomization are used to study containerless solidification of the Cu-Ni and Fe-Ni systems. Microstructure-selection maps are developed for the case of droplet solidification where droplet diameter and undercooling are the process parameters.

Microstructure Development: Solidification and Isothermal Aging
2014With the thermodynamic driving forces in mind, the observed microstructures and microstructural evolution that follows nonequilibrium solidification are discussed, with consideration of defect formation, intermetallic phases, and the influence of surface finish and microalloying on microstructure evolution.

Solidification and Microstructural Characterization on Atomized Powders
2009Atomizasyon teknikleri ile üretilen tozların homojen mikroyapı, düşük empürite içeriği ve arzulanan boyut aralığında üretimi gibi sunduğu birçok avantajlar doğrultusunda endüstriyel uygulamalarda kullanımı söz konusudur. Bu çalışmada santrifüj atomizasyonu ile üretilmiş demir ve demir dışı esaslı bazı alaşım tozlarının katılaşması irdelenmiş olup tüm ...

Modeling of microstructure formation during solidification
Analytical and numerical modeling has been developed to predict the solidification microstructure quantitatively in general and grain size in particular. It is found that the interface retardation caused by the solute build-up during solidification significantly influences solute redistribution to create the constitutional undercooling in the liquid ...openaire +2 more sources
