摘要：
In a color cathode ray tube, a shadow mask has a shadow mask thin plate that includes Fe—Ni. The shadow mask thin plate has a volume ratio, FR of &ggr;-FIBER to a crystal face having {100} cube orientation between 0.5 and 5.0. The volume ratio, FR, is determined according to equations (1), (2) and (3): FR = f ( g ) γ - FIBER ValueMean f ( g ) { 100 } ( 1 ) f ( g ) γ - FIBER ValueMean = f ( g ) { 111 } + f ( g ) { 111 } + f ( g ) { 111 } 3 ( 2 ) f ( g ) { hkl } [ uvw ] = ⅆ V ( g ) { hkl } [ uvw ] / V ⅆ g { hkl } [ uvw ] ( 3 ) wherein g={hkl}[uvw], and V=volume fraction.
