Laboratory for Texture and Related Studies

Members of this laboratory make use of various facilities housed in the laboratory itself, in the department as well as in the centralized facilities of the institute. The facilities used for current activities of this laboratory can be classified in to the following groups:

A. Materials Processing

Set up for Equal Channel Angular Extrusion (dies of different configurations used with a 100 ton hydraulic press) at room and high temperature

Extrusion press

A 2-Hi and 4 Hi rolling mill for (i) sheet/strip processing at room temperature, (ii) sheet/strip processing at high temperature, (iii) foil rolling and (iv) accumulative roll bonding

A channel die compression set-up coupled with servo-hydraulic DARTEC machine for carrying out plane strain deformation at constant true strain rates

Thin film deposition unit (These experiments are carried out in collaboration with Prof. S. Mohan of Department of Instrumentation)

B. Characterization of as-processed materials

Texture analysis by Electron backscatter diffraction (EBSD)

X-ray texture measurement

Texture measurement by neutron and synchrotron radiations

(These experiments are carried out in collaboration with Prof. H.-J. Brokmeier of GKSS Forschungzentrum, Geesthacht, Germany)

Scanning and Transmission electron microscopy

FIB

Characterization of Mechanical properties by INSTRON, ZWICK and DARTEC machines

Differential scanning calorimetry

Optical microscopy with quantitative image analysis

C. Softwares

Labosoft (texture analysis packages for detailed analysis of experimentally measured texture data)
