摘要： A tri-nickel aluminide base composition is provided which has good ductility at all temperatures. The composition has a relatively high concentration of cobalt substituent and is doped by boron. It also has minor concentrations of at least two other substituent metals selected from the group consisting of niobium, hafnium, vanadium, molybdenum and zirconium.

摘要： A method for contraction annealing niobium-tin wire is disclosed. An improved niobium-tin wire is provided by loosely winding the wire on a mandrel, or by coiling the wire on a circumferentially retractile mandrel, and contraction annealing the wire without reaction-forming substantial amounts of Nb₃Sn. Such contraction annealing allows the wire to contract in length unconstrained thereby preventing the formation of internal tensile stresses in the wire and its surrounding insulation. Prevention of internal stresses in the wire greatly reduces the susceptibility of the wire to breakage, cracking, sintering, shorting, tin leakage, or substantial shifting of the wire from desired wrap positions when it is reaction annealed to form the brittle superconducting intermetallic compound Nb₃Sn.

摘要： A tri-nickel aluminide base alloy composition is provided with a desirable combination of tensile strength and ductility. The composition is prepared to include boron dopant in combination with relatively low percentages of carbon for the high increase in strength achieved. The composition has an Ll₂ of crystalline structure. It is prepared by rapid solidification at a cooling rate of at least 10³°C per second.

摘要： Improvements in the positive temperature dependence of yield strength and in the work hardening rate of tri-nickel aluminide base alloys are achieved. The novel alloy composition has seven alloying ingredients as follows:
The novel composition may be prepared by forming a melt of the composition and atomizing the melt with an inert gas to form fine particles with Ll₂ type crystal structure. The powder is densified by heat and pressure to a novel alloy composition having the improvements in positive temperature dependence of yield strength and work hardening rate as noted above.-
