Evolution of Microstructure and Crystallographic
Texture during Thermo-Mechanical Processing by Warm-rolling
In A Duplex Stainless Steel.
PhD thesis, Indian Institute of Technology Hyderabad.
Abstract
Thermo-mechanical processing of materials involving heavy
deformation and annealing results in the development of
characteristic microstructure and crystallographic texture which
greatly affect their properties. As a result, the development of
microstructure and texture during thermo-mechanical processing
has been intensely investigated in a range of materials including
single phase metals and alloys, two phase materials and
intermetallic alloys. However, the development of microstructure
and texture in duplex alloys where both the phases have
polycrystalline grain structure, such as, (α+β) brass and
(ferrite+austenite) duplex stainless steels (DSS) has received far
less attention. Since these alloys constitute an important class of
structural materials adequate understanding of microstructure and
texture formation in these alloys will be key to enhance their
properties for a wide range of applications.
