Thermomechanical processing (TMP) and strain-induced phase transformation in titanium alloys

Chapter


Abstract


  • It is generally accepted that the physical and mechanical properties of metallic

    materials are primarily a function of the material’s composition and microstructure.

    These properties dictate the material’s ability to achieve preferred tasks and, therefore,

    determine the applications of that material. The microstructure itself is affected by many

    parameters including but not limited to manufacturing methods and techniques. Then, a

    thorough understanding of a materials microstructure, including how this may be affected

    or manipulated during manufacturing and processing, is desirable in order to assess the

    material’s suitability for a given application.

    Technical developments over recent decades, particularly in the aerospace industry,

    have driven development of new low density, high strength materials. In this field

    titanium and its alloys are particularly popular as they are able to produce high strength

    with low density and also offer good corrosion resistance in a wide range of

    environments. There is a large variety of titanium based alloys, with each having a

    different chemical composition and microstructure, producing a unique combination of

    properties, and hence a given specific family of applications to which it best suited.

    Despite the selection of a proper composition of Ti alloy for a certain application, the

    manufacturing methods and especially the controlling factors during manufacturing

    methods are significantly important to get desired mechanical properties from the final

    product. Thermomechanical processing (TMP), which is a combination of deformation

    and heat treatment, are among the most important industrial methods for manufacturing

    of different titanium parts in aerospace industry.

    With the increased interest in, and use of, titanium based alloys; there have been

    many studies concerning the thermomechanical processing and resulting microstructures.

    These studies have been predominately focused on development of new and novel TMP

    for manufacturing of high performance Ti alloys for aerospace and other industrial

    applications.

    This work refers some scientific issues on thermomechanical processing of titanium

    alloys. The microstructure development during TMP and different phenomenon including

    dynamic and static recovery and recrystallization has been explicated in detail. Also,

    “strain induced phase transformation” as a more complicated and powerful tool in

    controlling microstructure and mechanical properties during TMP of titanium alloys, has

    been explicit in detail.
