... at room temperature. However, some of the compositions are so highly alloyed that they cannot even be produced in wrought forms; they must be produced by alternate routes, such as casting or powder metallurgy. Superalloys are relatively heavy, with densities in the range of 7.8 to 9.4 g/cm 3 (0.282...

... characteristic of the period from 1960 to about 1980 was the trend to convert strong cast nickel-base superalloys to wrought products. IN-100, initially a cast alloy, was successfully adapted to a wrought form using powder metallurgy (P/M) processing to produce HPT turbine disks. Other variations of IN-100 (e.g...
