Superalloy foils by hot isostatic pressing

摘要

Dense superalloy foils are prepared by hot isostatically pressing a mixture of low melting alloy powders and high melting alloy powders at a temperature at least equal to or greater than three-quarters of the melting point of the low melting point alloy powder and below the melting point of the high melting point alloy powder, at a pressure of at least 10 thousand pounds per square inch for about one to five hours.
