... incomplete solidification occurred during the casting process. These defects are common to modern aluminum castings, even high purity castings that undergo hot isostatic pressing (HIP). The presence of these defects throughout the component represent low-energy paths for crack propagation. Fig. 8...

... of useful properties, such as hot hardness, corrosion resistance, particle cycling, and surface durability. For higher working temperatures, some cobalt-enriched hot isostatic pressing materials, such as Stellite 19PM and 25PM, also have been used with success. Group V and its different material...
