    • PROBLEM TO BE SOLVED: To provide an Ni-based alloy which is properly evaluated with respect to a nitride present in the inside and is excellent in mechanical characteristics, particularly, fatigue resistance.SOLUTION: In an Ni-based alloy, an estimated maximum size of the nitride is 25 μm or less in terms of area-equal diameter. The estimated maximum size of the nitride is calculated by calculating an area-equal diameter D defined by D=Arelative to the area A of the maximum size of the nitride present in a visual field through observation in a measurement visual field area S; repeating this operation with a measurement visual field number n to acquire data on the area-equal diameter D; rearranging the data on the area-equal diameter D in ascending order as D, D, ..., Dto determine a standardization variable j; determining a regression line y=a×D+b (a, b are constants) by plotting on an XY-axis coordinate with X-axis being the area-equal diameter D and Y-axis being the standardization variable y; determining ywith a prediction object sectional area S being 100 mm; and substituting the obtained yvalue to the regression line.
