Uranium-Molybdenum Alloys Containing 0.5 to 3 Per Cent by Weight of Molybdenum; ALLIAGES URANIUM-MOLYBDENE DE 0.5 a 3% EN POIDS DE MOLYBDENE. CARACTERISTIQUES GENERALES CINETIQUES DE TRANSFORMATION (in French)
The following properties have been determined in the new cast state of uranium alloys containing 0.5-1-1.8-2 and 3.5 per cent of molybdenum: micro-graphical aspect, crystalline structure, thermal expansion, the mechanical characteristics, behaviour when subjected to cyclic temperature variations, and heat treatment. The transformation curves have been established for continuous cooling at rates varying between 2.5 and 200 deg. C per minute, using a dilaon method for the alloys containing 1.0, 2.0 and 3.0 per cent Mo. T.T.T. curves have been traced for 0.5 and 1.0 per cent Mo alloys and the Ms points determined for alloys containing 2.0 and 3.0 par cent Mo. In this way it has been possible to show the different results of transformation, brought about either by nucleation and diffusion or by shear - the alloy containing 1 per cent Mo, give two martensites {alpha}' and {alpha}'' and the alloys containing 2 and 3 per cent Mo give one martensite with a band structure.
