  • Patent number: 10208364
    Abstract: A Ni-based alloy comprises nitrides, of which an estimated largest size is an area-equivalent diameter of 12 ?m to 25 ?m, the estimated largest size of the nitrides being determined by calculating an area-equivalent diameter D which is defined as D=A1/2 in relation to an area A of a nitride with a largest size among nitrides present in a measurement field of view area S0 of an observation of the Ni-based alloy, repeatedly performing this operation for n times corresponding to a measurement field of view number n to acquire n pieces of data of the area-equivalent diameter D, arranging the pieces of data of area-equivalent diameter D in ascending order into D1, D2, . . .

  • Patent number: 9828656
    Abstract: In a Ni-base alloy, an area-equivalent diameter D is calculated. D is defined by D=A1/2 from an area A of a largest nitride in a field of view when an observation area S0 is observed. This process is repeated in n fields of view for measurement, where n is the number of the fields of view for measurement, so as to acquire n pieces of data on D, and the pieces are arranged in ascending order D1, D2, . . . , Dn to obtain a reduced variate yj. The obtained values are plotted on X-Y axis coordinates, where an X axis corresponds to D and a Y axis corresponds to yj. In a regression line yj=a×D+b, yj is obtained when a target cross-sectional area S is set to 100 mm2. When the obtained yj is substituted into the regression line, the estimated nitride maximum size is ?25 ?m in diameter.
