Definitions

  • the conventional processes for the plastic deformation of metals by forging generally have as their object the shaping of such metals with a view to using them directly in the shape obtained or to permit the subsequent transformation thereof.
  • the deformation of a metal may be effected by applying a predetermined pressure on a surface element of the metal, this being done furthermore in a manner which is absolutely independent of the ambient hydrostatic pressure, since it will be remembered that the plastic deformation is effected without change in volume and density.
  • the invention consists mainlywhile simultaneously effecting the shaping under the hydrostatic pressure which is much higher than that necessary for effecting the deformation and which may reach as much as 12,000 barsin combining successive deformations, which are defined and limited in respect of their amplitude but are uniform in respect of the metal mass as a whole, and which are effected within a predetermined range, and also (where appropriate) annealing effected within predetermined cycles and for a predetermined period of time.
  • the invention consists furthermore, apart from this main arrangement, of certain other arrangements which are preferably utilized simultaneously and which may be considered either separately or in combination one with another, notably:
  • the metal to be deformed is disposed in a jacket made of a metal which is relatively less ductile at the temperature under consideration, and the shape and thickness of which are such that they oppose the proposed deformation,
  • the deformation is effected by forging
  • the deformation is effected by rolling
  • the deformation is effected by drawing
  • the said deformation is effected in an envelope in which a high pressure obtains due to the influence of artificial means such as high-pressure gas, a non-compressible liquid or a second metal which has been rendered plastic by the application of the pressure supplied by the first metal to be deformed, the said liquid or second metal or (if appropriate) gas being able to flow only through a small calibrated orifice and being, if appropriate, adjustable in such manner that it becomes possible to obtain a predetermined hydrostatic pressure rate during the operations,
  • artificial means such as high-pressure gas, a non-compressible liquid or a second metal which has been rendered plastic by the application of the pressure supplied by the first metal to be deformed, the said liquid or second metal or (if appropriate) gas being able to flow only through a small calibrated orifice and being, if appropriate, adjustable in such manner that it becomes possible to obtain a predetermined hydrostatic pressure rate during the operations,
  • the said metal to be deformed is beryllium
  • the said second metal is lead
  • the said second metal is aluminium
  • the said second metal is copper
  • the said second metal is Armco iron.
  • FIGURES 1 and 2 are diagrammatic views showing a shaping operation effected by forging in a jacket made of less ductile metals.
  • FIGURES 3, 4, 5 and 6 are diagrammatic views showing shaping by rolling in a jacket made of less ductile metals
  • FIGURES 7, 8, and 9 are diagrammatic views showing shaping by drawing in a jacket of less ductile metals.
  • FIGURE 10 is a diagrammatic view of shaping by forging in a high-pressure gas or non-compressible liquid
  • FIGURE 11 is a diagrammatic view showing shaping by drawing in a high-pressure gas or a non-compressible liquid.
  • FIGURE 12 is a diagrammatic view showing shaping by drawing in the presence of a second plastic metal.
  • FIGURES 13 and 14 are diagrammatic views showing shaping by forging in the presence of a second plastic metal.
  • FIGURES 1 and 2 show the jacketing of the metal 1 to be deformed with the aid of a metal 2 which is relatively less ductile at the temperature under consideration but is disposed in an envelope the shape and thickness of which are such that the proposed deformation is opposed, thus producing a high hydrostatic pressure in the interior.
  • This method is illustrated by FIGURES 1 and 2 which show the two upsetting states of a small metal cylinder 1 within a metal 2 which is less ductile.
  • FIGURES 3, 4, 5, and 6 show, respectively, operations involving the rolling'of a metal 1 within a metal 2 which 4 is less ductile, with regard to plates (FIGS. 3 and 4) with two rolling rolls and with regard to bars (FIGS. 5 and 6) with four rolling rolls.
  • FIG. 7 shows an operation involving the drawing of a metal 1 within a less ductile metal 2, this metal then being suitable for application to products of any desired section, the section of the less ductile material being, optionally, circular or of any other desired shape (FIGS. 8 and 9).
  • the metal 7 thus exerts a counter-pressure which may be varied by acting on the ratio So/Sl between the minimum values 5, 6 and maximum values 50, 60 or even 100.
  • the said metal 7 may be for example lead for temperatures below C., aluminium for temperatures between and 400 C., copper above this level or alternatively Anmco iron (an extremely pure grade of iron) for rapid forging operations.
  • a process for shaping difficult to deform ductile metals under high hydrostatic pressure comprising: confining a first ductile metal to be shaped in a first zone in a rigid container; confining a second ductile metal in a second zone in said rigid container in force-transmitting engagement with said first ductile metal; said second zone being configured to conform to the desired final shape of said first ductile metal, applying a pressure to said first ductile metal sufficiently high to force said first ductile metal to flow out of said first zone and into said second zone and to simultaneously force said second ductile metal to flow out of said second zone through at least one outlet orifice of predetermined size communicating with said second zone, said outlet orifice being of such a size as to require the application of a predetermined pressure to said second ductile metal by said first ductile metal to force said second ductile metal to flow therethrough.
  • said pressure applied to said first ductile metal is a substantially uniform pressure which is higher than a pressure necesa metal ofiers a substantially uniform resistance to the flow of said first ductile metal during the entire time said first ductile metal is being forced to flow from said first into said second zone.
