Definitions

  • the invention relates to foundry and rolling engineering.
  • Existing methods for producing structural materials for the automobile industry are generally based on the use of the traditional method for producing ingots from aluminum-based alloys containing magnesium, lithium, zinc, and so on, and for rolling the same.
  • the principal requirements made to structural materials for the automobile industry are the need to maintain the ultimate stress thereof within 300 to 400 MPa, relative elongation of 30% to 40%, and density not exceeding 2.65 g/cu.cm., good weldability, and corrosion resistance.
  • An aluminum-based alloy AMG5 (GOST Standard 478961) and a method for producing it are known in the prior art.
  • the prior art alloy has the following chemical composition (in percent by weight): Magnesium - 4.8 to 5.5 Manganese - 0.3 to 0.6 Titanium - 0.1 to 0.2 Iron - 0.5 to 0.6 Silicon - 0.1 to 0.2 Aluminum - the balance.
  • parabolic solidification fronts of a polycrystalline structure are the cause of the absence of a uniform crystallographic orientation, that is, plasticity is different across the ingot at the macro- and micro-level. In general, plasticity decreases by at least a half for this reason. Plasticity of an alloy is characterized by relative elongation of up to 4%-6%, a figure that obviously does not meet the requirements of the automobile industry.
  • Processes for producing the AL8 and AL27 alloys related closely to the chemical composition of this invention are suitable for producing corrosion-resistant castings that can be subjected to heat treatment to improve their strength. These processes, however, can be used to cast ingots from the above alloys only. Besides, they cannot, in principle, be used to make plastic ingots from alloys containing about 10% of magnesium, for which reason they are classified as foundry processes.
  • This invention is intended to develop a method for producing a structural material from an aluminum-based alloy containing 9% to 10% of magnesium, comprising casting an ingot, subjecting the ingot to heat treatment, and rolling the ingot, in order to improve the strength and plasticity of rolled products and the quality of the process for producing sheet material.
  • This objective is achieved by developing a method for producing a structural material from an aluminum-based alloy containing 9% to 11 % of magnesium, said method comprising producing an ingot, subjecting it to heat treatment, and rolling the ingot containing magnesium, manganese, and titanium, wherein the mechanical properties of the alloy are improved by further adding zirconium, cobalt, beryllium, and boron thereto at the following proportions of the ingredients (in percent by weight): Magnesium - 9.0 to 11.0 Zirconium - 0.15 to 0.2 Cobalt - 0.01 to 0.001 Beryllium - 0.001 to 0.02 Aluminum - the balance.
  • Solidification is carried out in a revolving mold at a gravitation factor of 220 to 250 during a lifetime of the melt equal to between 12 and 15 sec/kg.
  • Heat treatment and rolling are conducted according to the following algorithm:
  • the claimed method is based on the use of new physical phenomena attending solidification of melts in strong gravitation fields of centrifuges. Generally, the effect of such fields is as follows:
  • the claimed method therefore, helps develop an aluminum-based structural material containing 9% to 11 % of magnesium, and make rolled products therefrom.
  • the method of this invention for producing a structural material from an aluminum-based alloy containing 9% to 11 % of magnesium is performed at the ingot producing stage in a revolving mold, the design of which depends on the required ingot shape and weight. In this case, the thermal conditions of solidification depend on the specific design of the mold lining.
  • the invention is based on an analytically computed and experimentally confirmed effect of gravity fields on the solidifying melt from the viewpoint of orientation of the crystallographic lattice axes.
  • a retarded crystallite is a fully grown nucleus distorted from the spherical shape to nearly an ellipsoid attached to the cellular solidification front.
  • Direction of the absolute elastic energy minimum of the lattice is a maximum suitable situation for successive deformation of the solid at minimum external forces applied, for example, by the rolling mill. This is particularly important in this case, with a supersaturated solution of magnesium in aluminum, because this alloy has an improved strength.
  • Table 1 Test parameters Rolled product thickness, mm Magnesium concentration, % 2.0 1.0 0.5 0.1 Ultimate strength, MPa 320-380 320-380 325-380 330-390 9 330-400 330-400 330-410 330-420 10 330-390 330-390 320-390 325-380 11 Relative elongation, % 30-40 32-40 32-40 9 32-40 32-40 32-40 33-40 10 31-38 30-37 30-36 30-36 11
  • This invention is suitable for application on an industrial scale because it may be performed in a revolving mold known in the art, and the result is achieved by varying alloy production conditions.
  • This invention may be used for producing structural materials of practically any thickness from the AMG10 alloy.
  • the invention may be used most efficiently for producing rolled materials for motor vehicle bodies and power components of motor vehicles.
