Tensile properties amd impact strengths were determined for iodide Zr, sponge Zr, and alloys based on both grades of metal, containing nominally 1.5% M. Sheet specimens, welded and unwelded, were tested. Tensile properties were established at room temperature and 300 deg C. Impact strength values were measured at --100 deg , R.T., 100 deg , 200 deg , and 300 deg C. These (alpha) materials generally exhibited a lack of heat treatability, litile or no deterioration of properties due to welding, and essentially no indication of impact transition temperature. Tensile strength and impact behavior were established for alloys based on iodide zirconium containing 15% Nb, 15% Nb + 2% Pd, 15% Nb + 2% Pt, 15% Nb + 1% Fe, and a binary sponge zirconium + 15% Hb alloy. High strength levels could be established by proper heat treatment. The presence of Pd, Ft, or Fe seemed to delay the formation of the embrittiing agent as determined by hardness and resistivity vs time of anneal curves for these alloys. uth)
