cct for precipitation in aluminum alloy

Sinppa Industry was established in 2004. It occupies 120,000㎡with monthly production capacity of 2,500 tons aluminum ingot, and more than 40 existing staff. Sinppa adheres to produce quality aluminum products with the professional equipments, advanced technology and scientific management.

Sinppa also invests the Sinppa Industrial (Malaysia) with monthly production capacity of 5,000 tons aluminum for the first phase to play a vital role in the global aluminum recycling ecosystem, processing scrap metal from sources such as shredded autos to produce specification aluminum ingot and alloys. The finished products are widely sold to manufacturers of auto and motorcycle parts, construction, and other industrial and commercial products.

    In order for an alloy system to be able to be precipitation-strengthened, there must be a terminal solid solution that has a decreasing solid solubility as the temperature decreases. The Al-Cu (Duralumin is an aluminum alloy of 2XXX group) phase diagram shown in Figure 1 shows this type of decrease along the solvus between the α and α+θ regions.

    Thermal analysis, especially Differential Scanning Calorimetry (DSC) provides an approach for CCT-diagrams of aluminium alloys, if the relevant quenching rates can be realized in the DSCequipment. The aluminium alloy Al-4.5Zn-1Mg (7020) is known for its relatively low quenching sensitivity as well as for its technical importance.

    The most important heat treatment to increase the strength of aluminum alloys is precipitation hardening, which is composed of three steps: solution annealing, quenching and ageing. The maximal strength values can be achieved only when age hardening aluminum alloys are quenched above a critical rate.

  • Aluminum and Aluminum Alloys - materialsdata.nist.gov

    Aluminum alloys are second only to steels in use as structural metals. Aluminum has a density of only 2.7 g/cm3, approximately one-third as much as steel (7.83 g/cm3). One cubic foot of steel weighs about 490 lb; a cubic foot of aluminum, only about 170 lb.

  • Continuous cooling transformation curve of a novel Al-Cu-Li alloy

    The CCT curves are important for heat treatment of aluminum alloys because they provide information about the required quenching rate. HERDING et al[10] have measured CCT curves of aluminum alloys using a differential scanning calorimeter(DSC) at cooling rates of 5 to 475 /min, but these results are too simple and not applicable to the manufacturing of the alloy.

  • Heat Treatable Aluminum Alloys - Total Materia

    These usually are referred to as the “heat-treatable” alloys to distinguish them from those alloys in which no significant strengthening can be achieved by heating and cooling.Heat treatment to increase strength of aluminum alloys is a three-step process: Solution heat treatment: dissolution of soluble phases; Quenching: development of supersaturation; Age hardening: precipitation of solute atoms either at room temperature (natural aging) or elevated temperature (artificial aging or ...
