Abstract

The disclosed erosion-resistant and wear-resistant Ti-Ni-M₁ alloy contains 42.5 to 54.5 atomic percent of titanium, M₁ being at least one of Ta, Nb, W, Hf and Mn, the ratio of the atoms of M₁ to the total atoms other than Ti being 1 to 55%.

Claims

1. An erosion-resistant and wear-resistant Ti-Ni-M₁ -M₂ alloy consisting essentially of 42.5 to 54.4 atomic percent of Ti, in which M₁ is Ta or Nb and M₂ is Mo, and the atomic ratio of M₁ + M₂ to the total atoms other than Ti is 1 to 55%.

2. An erosion -- resistant and wear-resistant Ti-Ni-M₁ -M₂ alloy consisting essentially of 47-52 atomic percent of Ti, in which M₁ is Ta or Nb and M₂ is Mo, and the atomic ratio of M₁ + M₂ to the total atoms other than Ti is 1 to 35%.

3. An erosion -- resistant and wear -- resistant Ti-Ni-M₁ -M₂ alloy consisting essentially of 48 to 51 atomic percent of Ti, in which M₁ it Ta or N_b and M₂ is Mo, and the atomic ratio of M₁ + M₂ to the total atoms other than Ti is 1 to 25%.
