A method is provided for imparting a fine grain structure to aluminum alloys which have precipitating constituents. The alloy is first heated to a solid solution temperature to dissolve the precipitating constituents in the alloy. The alloy is then cooled, preferably by water quenching, to below the solution temperature and then overaged to form precipitates by heating it above the precipitation hardening temperature for the alloy but below its solution treating temperature. Strain energy is introduced into the alloy by plastically deforming it at or below the overaging temperature used. The alloy is then subsequently held at a recrystallization temperature so that the new grains are nucleated by the overaged precipitates and the development of these grains results in a fine grain structure.

The alloy is then cooled, preferably by water quenching, to below the solution temperature and then overaged to form precipitates by heating it above the precipitation hardening temperature for the alloy but below its solution treating temperature. Strain energy is introduced into the alloy by plastically deforming it in a temperature range of 380. degree. F. to 450. degree. F. to reduce its cross-sectional area a total of 40% minimum, at least 25% of the reduction in area being accomplished in a single continuous deformation operation. The alloy is then subsequently held at a recrystallization temperature so that new grains are nucleated by the overaged precipitates and the development of these grains results in a fine grain structure.

A method is disclosed for scribing chemical milling maskant applied to a metal substrate by impinging a laser beam on the maskant and controlling the beam to penetrate through the maskant substantially without damaging the underlying metal. In carrying out the process, a metal part such as aluminum, titanium or their alloys is coated with an organic polymer maskant having absorption to a laser beam, a predetermined pattern is scribed in the maskant by impinging a laser beam, e. g. a Nd:YAG (neodymium doped yttrium aluminum garnet) laser, under controlled conditions to scribe a predetermined pattern in the maskant and substantially without damaging the underlying metal, removing the maskant portion within the circumscribed area of the pattern to expose the underlying metal and leaving the remaining maskant portion adhered to the substrate, immersing the metal substrate in a chemical milling solution, e. g. an alkali solution, under controlled conditions to remove a predetermined thickness of the exposed metal from the substrate, and thereafter removing the remaining maskant portion from the substrate.

A method is provided to impart a fine grain structure to aluminum alloys which have precipitating constituents. The alloy is overaged to form coarse precipitates, and then plastically deformed at least 40%. Deformation is accomplished at a temperature and at a rate which are sufficient to retain strain energy in the alloy at the end of the deformation step. The alloy is subsequently heated at a rate of at least 0. 02. degree. F. multidot. s. sup. -1 to a recrystallization temperature to form a new fine grain structure.

A method and apparatus are provided for automatically controlling the strain rate during superplastic forming of a blank of material into a part. The method and apparatus produce a part in a minimum time by deforming the material in its optimum superplastic conditions. A relationship is determined between time and the pressure required to form the blank against the configured surface of a die at a strain rate which causes the blank to flow superplastically. The blank is positioned in the die and held at a temperature at which the material exhibits superplasticity. Pressure is automatically applied across the thickness of the blank in accordance with the previously determined relationship between time and pressure until the part is formed. The apparatus comprises conduits connected to a die and to a high pressure gas. Valves in the conduits regulate the pressure applied to the blank.

A titanium base alloy with improved superplastic properties is provided. The alloy has 6% Al and from 1. 5 to 2. 5% of a beta-stabilizing element which has high diffusivity in titanium, namely Co, Fe, Cr, or Ni. In a preferred embodiment, the alloy is a Ti-6Al-4V type alloy modified by the addition of about 2% Fe.
