Abstract
The casting porosity of an unwrought casting made from an alloy having a large difference between its liquidus and solidus temperatures is reduced by subjecting the casting to hot isostatic pressing.
Claims6
A process for enhancing the properties of a casting made by turbocasting a molten alloy composed of 8 to 16 wt. % Ni and 5 to 8 wt. % Sn, with the balance being Cu and incidental impurities, the process comprising subjecting the casting to hot isostatic pressing.
