  • Method of and a spray for manufacturing a titanium alloy
    Patent number: 4902355
    Abstract: A method of manufacturing a titanium alloy, wherein a melted and possibly preformed part is annealed to set the starting grain structure, wherewith a first grain structure transformation is accomplished by a first cooling step, whereafter high dislocation densities are produced in the course of a hot forming step, whereupon heat treatment involving a recrystallization is carried out, wherewith in the course of a subsequent cooling a predominantly or substantially martensitic breakdown is achieved, wherewith a grain structure transformation is carried out in a subsequent annealing process, and wherewith in the course of a subsequent chilling a fine grain structure is set. At least the first cooling step is accomplished by spraying the preformed part with water and/or water-air mixtures. A spray device may be used for carrying out the method.
