Copper Alloys and Its Heat Treatment Metallurgy

Heat Treatment of Aluminum Bronzes:I. Alpha Single Phase Aluminium Bronze (up to 10% Al):These alloys can be strengthened only by cold working, and can be made soft by recrystallisation annealing at 425°C to 760°C. The non-age hardenable single phase alpha can be made age-hardenable by adding cobalt, titanium and nickel. The following table gives properties of two such alloys:II. Two-Phase Alloys: Heat Treatment of Nickel Aluminum Bronze Alloys - National Nov 19, 2019 · In this alloy heat treatment is used to give this cast alloy similar mechanical properties to the extruded version. This alloy is also quench hardened and temper annealed. Heat treatment can be a useful technique used to both relieve stress and improve

  • Background of The InventionBrief Summary of The InventionBrief Description of The Several Views of The DrawingDetailed Description of The InventionExample 1Example 2Example 3Example 4Example 5Certain embodiments of the present invention are directed toward methods of heat treating nickel-base alloys. For example, according to one non-limiting embodiment there is provided a method of heat treating a nickel-base alloy comprising pre-solution treating the nickel-base alloy wherein an amount of at least one grain boundary precipitate selected from the group consisting of -phase precipitates and -phase precipitates is formed within the nickel-base alloy, the at least one grain Heat TreatmentAlthough more stable than other nickel-molybdenum alloys (particularly its predecessor, B-2® alloy), it is still prone to significant, deleterious, microstructural changes in the temperature range 1100-1500°F (593-816°C), especially after being cold-worked.

    Heat Treatment of Nickel Alloys Metallurgy

      Heat Treating Nickel Alloys Corrosion MaterialsAlmost all heat treatments used on nickel alloys are done to soften the alloy or to increase the strength in the precipitation hardenable alloys. The purposes of heat treatments are:Remove stresses introduced into the alloys during cold work; Restore ductility; Reduce tensile properties; Strengthen the material; Depending on the design and end use combined with the exact chemical composition of the alloy, several types of heat treatment of nickel alloys
