It has been found that when a single roll melt spinning method is carried out under an inert gas atmosphere of r, superalloy thin strips with good surface quality and no oxidation can be continuously obtained. Although the reason for this is not clear, as shown in FIG.
It is thought that this is because inert gas is adsorbed on the outer surface of the liquid phase paddle 15 located immediately in front of the liquid phase paddle 15, and the shape of the liquid phase paddle 15 is stabilized due to the relationship between the presence of the inert gas and the change in surface tension. In addition, in order to obtain a superalloy thin strip plate with uniform width and thickness,
The temperature of the molten metal 5 in the crucible 2, the jetting pressure (spraying speed) of the molten metal 5 from the nozzle part 3, and the temperature and rotation speed of the rotary cooling body 6 may be maintained constant.
