MM 5013 Textures in Materials

Syllabus:

Representation of macro, micro and meso-texture.

Measurement and analysis of macro, micro and meso-texture

using X-ray, neutron and electron diffraction techniques.

Materials processing-texture correlations in different classes of materials (metals and ceramics).

Texture control. Texture-properties correlations with case studies on

Structural materials (eg: steels, Al alloys, Mg alloys, Ti alloys)

Functional materials (for eg: superconducting (YBCO) thin films

Role of grain boundary character on interface controlled properties (segregation, creep, fracture, sensitization). Concept of grain boundary engineering

Learning Objectives:

Appreciation of the role of textures in materials,

Representation, measurement and analysis of textures (macro, micro and meso)

Correlate texture development with materials processing
