Abstract

See full text

A melt-solidified substance includes melt-solidified portions formed by welding, build-up spray welding, metallizing or fusing. The melt-solidified portions have the alloy composition containing Zr: 0.0005 to 0.05 mass %, P: 0.01 to 0.34 mass %, Cu: the remainder and satisfying the relationship between the contents of P and Zr, [P]/[Zr]=0.3 to 20, and the mean grain size in the macrostructure after melt-solidification is 300 μm or less. If Fe and/or Ni are contained in the melt-solidified portion as inevitable impurities, the content of Fe or Ni is restricted to be 0.3 mass % or less when either Fe or Ni is contained, and the total content of Fe and Ni is restricted to be 0.4 mass % or less when both Fe and Ni are contained.
