It is possible to obtain castings from this alloy with a good combination of casting and mechanical properties with a content (wt.%) of 2-6% Ni, 1-3% p, 1% Fe, less than 1% silicon, and also with the content of other unavoidable impurities.

  • corrosion resistance is maintained at a good level.
  • the main criterion for the acceptable choice of alloying elements was the formation of the desired structure, excluding the presence of coarse primary crystals and/or coarsening of the eutectic phase; the rationale for the concentration range is given below.
  • the concentration (wt.%) of calcium in the range of 1.5-5.1% and zinc in the range of 0.1-1.8% provide good casting properties due to the fact that calcium and zinc mainly form a sufficient amount of the eutectic phase.
  • the main effect of the joint introduction of calcium and zinc is the formation of a joint eutectic phase A14(Ca,Zn), where the zinc atom replaces the calcium atom.
  • the level of strength properties is further increased. If the calcium content is less than the declared level, it will lead to a decrease in casting characteristics. When zinc is reduced below the stated level, there will be no significant increase in strength properties.
  • the content of calcium and zinc above the stated level will lead to the formation of a rough structure and a significant decrease in mechanical properties.
  • the content of iron and silicon is primarily determined by the purity of the aluminum used in the preparation of the alloy.
  • iron and silicon can also be used as alloying elements, due to the fact that silicon in an amount of up to 1.0 wt.% is redistributed between the solid solution and the eutectic, which, on the one hand, provides an increase in strength properties due to additional solid solution hardening in the cast state, and on the other hand, it positively affects the casting characteristics of the alloy due to an increase in the amount of eutectic. With a higher content of silicon, the morphology of the eutectic phase worsens, which generally reduces the strength characteristics.
  • Iron in an amount of up to 0.5 wt.% predominantly forms phases of eutectic origin, which positively affects the casting characteristics of the alloy due to an increase in the amount of eutectic. With an increase in the concentration of iron above 0.5 wt.%, coarsening of the eutectic phase is possible and, as a result, a decrease in mechanical properties.
  • Manganese in an amount of up to 2.5 wt % is necessary to improve the strength properties, primarily in the cast state, by providing solid solution strengthening.
  • the manganese content is above 2.5 wt.% in the structure, primary crystals of the Alb(Te, Mn) phase can be formed, which can lead to a decrease in mechanical characteristics.
  • the content of manganese is less than 0.2 wt.% will not lead to significant solid-solution hardening and, as a consequence, a weak increase in strength characteristics.
  • Zirconium and chromium within the stated limits (wt.%) 0.05-0.14% and 0.05-0.15%, respectively, are necessary to ensure solid solution strengthening. At lower concentrations of these elements, a significant increase in strength characteristics in the cast state is not achieved. For large quantities, it will be necessary to increase the casting temperature above the typical level, which will reduce the durability of the casting molds, otherwise, there will be a high probability of the formation of primary crystals of the AlCr and AlsZr phase, which will not lead to an increase in the level of mechanical properties from the introduction of these elements.
  • Titanium in the amount of 0.005-0.1 wt.% is necessary for modifying the aluminum solid solution. With a higher content of titanium in structure, the appearance of primary crystals is possible, which will reduce the overall level of mechanical properties, and at a lower level, the positive effect of the influence of this element will not be realized. Titanium can be introduced in the form of a multicomponent alloy, such as Al-Ti-B and/or Al-Ti-C, so in this case, the presence of boron and carbon in compounds with titanium is possible in the alloy, in amounts proportional to the content of the corresponding alloy. Boron and carbon, as independent elements, did not have a significant effect on the mechanical and casting properties in relation to the range under consideration. In addition, in the presence of titanium, in some cases, a decrease in the tendency to form hot cracks during casting is noted.
  • alloys For the preparation of alloys, the following charge materials were used (wt.%): A99 and A8 grade aluminum, TsO grade zinc, calcium in the form of calcium metal and A1-6Ca master alloys, manganese in the form of A1-10% Mn master alloy, Al-10% Zr master alloy , Al-10%Cr, Al-5%Ti.
  • Table 1 Chemical composition of experimental alloys (wt.%) The content of other elements typically did not exceed 0.05 wt.%.
  • the chemical composition of the alloy was chosen from the condition of obtaining a structure consisting of an aluminum solid solution and a eutectic component. Casting of samples was carried out by gravity method in a metal mold "Separately cast sample". Form temperature - could fluctuate in the range of 20 -60 °C. The casting was a tensile specimen with a diameter of 10 mm and a calculated length of 50 mm, which was tested for tension (with the determination of the yield limit, tensile strength, and relative elongation) immediately after casting without machining. The structure of the samples was evaluated from the sample heads.
