HARDNESS CONVERSIONS FOR ZIRCONIUM BASE ALLOYS

Hardness conversion curves in the range 100 to 600 DPH were obtained for zirconium-base alloys, utilizing conventional micro- and macrohardness techniques. Large standard deviations resulted in the Knoop harduess scale in the range 500to 600 KHN with an applied load of 10 g. The utility and limitations of the hardness conversion curves are briefly discussed. (auth)
