An x-ray analysis of zirconium --molybdenum--tin alloys annealed at 900 deg C revealed that the amount of Mo affects the beta -phase transformation into an alpha ' phase with an alpha -zirconium lattice or into the omega -phase with a hexagonal lattice. The greatest hardness is achieved during the transition from the beta -phase into the omega -phase. The alpha ' phase, saturated with molybdenum and tin, disintegrates at 250 to 450 deg C according to the annealing scheme. The greatest hardness, H = 350 kg//sub mm/2, is achieved with 400 deg C tempering. At 500 deg C the hardness is lowered to 250 kg//sub mm/ 2. Alloys in beta + omega phases after annealing increase their hardness from 330 to 450 kg//sub mm/2 with an increase in annealing temperature from 150 to 300 deg C. (R.V.J.)
