    摘要: An Ni-base superalloy suitable for use as the material for gas turbine disks or the like has a composi­tion containing, by weight, 0.01 to 0.15% of C, 15 to 22% of Cr, 3 to 6% of Mo, 3 to 6% of W, 5 to 15% of Co, 1.0 to 1.9% of Al, 1.5 to 3.0% of Ti, 3.0 to 6.0% of Ta, 0.001 to 0.020% of B and the balance substantially Ni except inevitable impurities. Ni may optionally be present, replacing some of the Ta content. This alloy can be produced using the conventional ingot making and hot working process and then subjected to direct aging and, as a result, it exhibits excellent strength properties well comparable to those of expensive alloys produced by powder metallurgy process.
