Abstract: Manufacture of a fluid connector fitting from an elongate metal stock, such as a plate or barstock, or a billet having an indefinite length and the potential for one or more centerline inhomogeneities which may extend along a longitudinal central axis thereof. In one embodiment, a metal stock is provided as having a cross-section of a first dimension which may be at least about equal to the extent of a first or second widthwise extent of the fitting and a second dimension which is at least about twice the extent of the other widthwise extent of the fitting. The stock is sectioned through the second dimension thereof along its longitudinal central axis to equally divide it into at least first and second workpieces. Each of the workpieces extends along a corresponding longitudinal axis thereof and has a cross-section of a first and a second width which may correspond, respectively, to the first and second widthwise extents of the fitting.

Abstract: Mixed metal oxides are prepared as catalyst materials by a method comprising high energy impact milling of a formulated mixture of powders to form a mechanically alloyed product and heat treating said product in an oxidizing atmosphere to form the desired compound. In a preferred embodiment a catalytic material is formed which has the general empirical formula ABO.sub.3 and a perovskite-type crystal structure.

Abstract: Prealloyed powders, particularly of compositions which are difficult to work by conventional means, are subjected to forces such that strain energy is imparted thereto by virtue of which the prealloyed powders manifest low flow stress and a high degree of thermoplasticity.
