The successful analysis of the as solidified Fe 6.5%Si alloy prepared by rapidly solidification shows that as a powerful tool of grain boundary design and control,EBSD technique is of unique superiority for the characterization of grain boundary structure.
The results showed that the viscosity and superheat degree of the melt, the diameter of efflux beam and ejection velocity ofthe melt,the rotational speed of blade and hitting radius had a marked influence on thethickness of metal foil by rapidly solidification.
The formula of calculating thickness of metal foil by rotation blade quenching(RBQ) during rapidly solidification was derived,based on the principle of energy conservation. The dynamics studies was carried out on the formation of metal foil by rapidlysolidification and its influencing factors in computer.
The conclusion is drawn that the strength of the materials extruded from rapidly solidified ribbons depends on their microstructure and extrusion conditions.
Comparative analysis of properties of rapidly solidified foils of Al-Ni-Cr alloys obtained by one-side cooling (melt spinning) a
Using these thermophysical parameters, the relation between solute trapping and undercooling in rapidly solidified α-Ni was calculated, and the theoretical prediction shows a good agreement with experimental data.
The ceramal composite coating has a rapidly solidified microstructure consisting of primary Cr7C3 and the Cr7C3/γ-Fe eutectics, and is metallurgically bonded to the degree C steel substrate.
