摘要： A powder metallurgy article formed from a Co-Cr-Mo alloy powder and a method for making the article are disclosed. The Co-Cr-Mo alloy powder contains, in weight percent, about 0.35% max. C, about 1.00% max. Mn, about 1.00% max. Si, about 26.0-30.0% Cr, about 5.0-7.0% Mo, about 3% max. Ni, about 0.25% max. N, about 1.00% max. Fe, about 0.01% max. of oxide forming metals, and the balance is essentially Co. Within their respective weight percent limits C and N are controlled such that they satisfy the relationship: 62.866+360.93x(%C)+286.633x(%N)-682.165x(%C)2-641.702x(%N)2>/=120.

摘要： A high-Cr nickel alloy having excellent resistances to wear and lead corrosion and containing 0.01-0.5 wt.% C, 0.01-1.0 wt.% Si, 0.01-10.0 wt.% Mn, 35.0-60.0 wt.% Cr, 5.0-25.0 wt.% Fe, 8.0-15.0 wt.% Nb, and the balance consisting of Ni, and inevitable impurities. As the addition of Nb causes fine rigid particles of Nb-Ni and/or Nb-Fe intermetallic compounds to be dispersed and deposited reticularly in a matrix, a sufficient wear resistance can be attained and the attack to the mating materials can be inhibited. When toughness is of primary concern, it is preferably to add 0.01 to 1.0 wt.% Mn, because the toughness is particularly high and defectives due to cracking in surfacing are reduced in this range. When, however, lead corrosion resistance is of primary concern, it is preferable to add over 1.0 to 10.0 wt.% Mn, because the lead corrosion resistance in a reducing atmosphere such as an actual engine combustion gas is particularly high in this range.

摘要： A vapor deposition material is provided for the production of VTR tapes, vertical magnetic recording thin films, etc. The vapor deposition material is wire made of cobalt with unavoidable impurity, a cobalt-nickel alloy containing up to 30 wt % cobalt impurities, and the balance of unavoidable impurities, or a cobalt-chromium alloy containing up to 30 wt % chromium and the balance of unavoidable impurities. This wire has a diameter of from 1.0 mm to 10 mm, a tensile strength of 400 MPa to 1,500 MPa and elongation and contraction of at least 5 %. The vapor deposition material has a predetermined crystalline structure, and a proportion of the face-centered cubic lattice is 0.1 to 1. To obtain such properties, the material is heated to Tu DEG C and then subjected to plastic working at a temperature between Td DEG C and Tu + 200 DEG C in such a manner that the reduction of area per pass is more than 10 %, where Tu is the transformation temperature during heating for a change from close-packed hexagonal to face-centered cubic while Td is the transformation temperature during cooling for a change from face-centered cubic to close-packed hexagonal. When the wire material is made of the cobalt metal or the cobalt-nickel alloy, 0.01 to 0.1 wt % of either one of the elements selected from the group consisting of Mn, Cr, Mg, Zr and Ca is preferably contained. When the wire material is made of the cobalt-chromium alloy, 0.01 to 0.1 wt % of either one of the elements selected from the group consisting of Mn, Mg, Zr and Ca is preferably contained.
