  • Titanium alloy heat treatment - annealing (6)


    (6) Double annealing The difference between double annealing and isothermal annealing is that in the first stage after double annealing, the alloy is cooled to room temperature in air, and then the alloy is reheated to the temperature of the second stage (this temperature is lower than the temperature of the first stage). The advantage of double annealing is that a part of the ...

  • Titanium alloy heat treatment - annealing (5)


    Isothermal annealing Isothermal annealing: The workpiece is heated to a higher temperature sufficient for recrystallization to be cooled, and then cooled to a temperature at which the β phase has high stability (this temperature is generally lower than the recrystallization temperature), maintained at this temperature, and then cooled in air. Compared with simple annealing, the...

  • Titanium alloy heat treatment - annealing (4)


    Vacuum annealing The hydrogen content of the titanium alloy surface layer is reduced to a safe concentration, eliminating the possibility of hydrogen embrittlement. In addition, the residual stress is reduced and the mechanical properties and performance of the alloy are ensured. The purpose and significance of the above four heat treatments are clear, but the concepts of isoth...

  • Titanium alloy heat treatment - annealing (3)


    Recrystallization annealing The annealing process is performed by heating the workpiece to a temperature above the recrystallization temperature. In this annealing, recrystallization mainly occurs, so that work hardening is eliminated, the structure is stabilized, and the plasticity is improved. The annealing temperature is between the recrystallization temperature and the phas...

  • Titanium alloy heat treatment - annealing (2)


    Simple annealing In order to eliminate residual stress, the workpiece is heated to an annealing process slightly below the recrystallization starting temperature. This type of annealing is a common type of metallurgical product when it leaves the factory. www.feihongalloys.com

  • Titanium alloy heat treatment - annealing (1)


    The main types of titanium alloy annealing include: stress relief annealing, simple annealing, isothermal annealing, double annealing, recrystallization annealing, and vacuum annealing. (1) Stress relief annealing In order to eliminate internal stress generated by processes such as plastic deformation and welding, the workpiece is heated to an annealing process below the recrys...

  • Alloy classification (2)


    Zinc alloy: The main added elements of zinc alloy are aluminum, copper and magnesium. According to the processing technology, zinc alloy can be divided into two types: deformation and cast zinc alloy. Cast zinc alloy has good fluidity and corrosion resistance, and is suitable for die-casting instruments, automotive parts and the like. Magnesium alloy: The alloying elements in t...

  • Alloy classification


    Copper alloys: Common copper alloys are brass, bronze and white copper. Aluminum alloy: According to the composition of aluminum alloy and the characteristics of production process, it is usually divided into two major categories: deformation and cast aluminum alloy. Industrial applications are mainly aluminum-manganese, aluminum-magnesium, aluminum-magnesium-copper, aluminum-m...

  • Non-ferrous metal material classification method (3)


    Classified by production and application 1. Non-ferrous smelting products: Refers to various pure non-ferrous metals or alloy products obtained by smelting methods. 2. Colored processed products (or deformed alloys): Refers to various colored semi-finished materials such as tubes, handles, wires, patterns, plates, foils, strips and belts produced by mechanical processing method...
