Microstructure, thermal and x-ray-diffraction analyses, and hardness tests were used in plotting the constitution diagram of Nb-Sn. The compound Nb/ 3/Sn was formed at 2000 plus or minus 25 deg C. Liquid alloys with 60 wt.% Sn and over are laminated. The temperatare of monotectic reaction is 730 plus or minus 5 plus or minus C. A considerable diffusion area was found at the niobium side. The Nb/sub 3/Sn (29.87 wt.% Sn) has a structure with a plus or minus 5.29 A. The Vickers hardness is 900 kg/mm/sup 2/. The transition to the superconducting state is at approximately 18.05%DEK. Solid solutions of niobium and tin have better hardness and oxidation resistance than pure niobium. (R.V.J.)
