2002 TMS Annual Meeting & Exhibition: Short Courses—Texture and Anisotropy for the Materials Profession

February 17–21 · 2002 TMS ANNUAL MEETING · Seattle, Washington




Professor Anthony D. Rollett has worked for Carnegie Mellon University as Professor, Department of Materials Science & Engineering as Department Head since 1995. Prior to joining CMU, Prof. Rollett was with Los Alomas National Laboratory from 1979 to 1995. His current research interests focuses on the relationship of mechanical properties to microstructure, and on improving our understanding of how microstructures evolve. The use of computers is emphasized for processing large volumes of data and
for simulating the behavior of materials, from grain growth to plastic flow. He is leading a project on anistropic interfaces and their impact on microstructural evolution as part of the DOE’s Computational Materials Sciences Network.
Professor Rollett remains very active within TMS having served on numerous technical committees and as JOM Advisor. In addition, he actively publishes in technical journals.

Who Should Attend:
Have you always wondered what “pole figures” were all about? This course will bring you up to speed on texture (i.e. crystallographic preferred orientation) and anisotropy (e.g. different yield strengths in different directions). You will learn how to read pole figures and orientation distribution plots. The meaning of Euler angles and texture components will be explained. Basic concepts in anisotropic material properties such as modulus, strength and r-value will be related to texture.

If you work with polycrystalline materials, the chances are good that they have some degree of texture and therefore some anisotropy. Thus anyone who needs to understand how to measure texture and what tools are available to quantify it (e.g. popLA) will find this useful. A background in Materials Science & Engineering will be assumed (or some knowledge of crystal structure and diffraction).

Course Overview:
Many unresolved issues exist in microstructural evolution such as the variations in grain boundary energy with misorientation, and the origin of strong recrystallization textures in the annealing of metals. Simulation techniques such as the Potts model are used to study grain growth, secondary recrystallization and recrystallization. Experimental and theoretical investigations of, for example, the early stages of recrystallization are revealing the critical features of nucleation of new grains.

Texture-anisotropy-plasticity relationships are being investigated in a wide range of materials. This field has been rejuvenated recently by the advent of Orientation Imaging Microscopy, on-line texture measurement and the ability to apply personal computers to the analysis of texture data. Control of texture for formability and other properties is still a significant issue for the metals industry. Learning how to process and optimize advanced materials and composites such as those based on intermetallics brings numerous challenges in micromechanics. Many materials are highly anisotropic and yet conventional processing fails to take the opportunity to engineer this aspect of materials. A fundamental theme that connects the study of microstructure and mechanical properties is the understanding of how microstructure evolves during deformation processing and how it influences the properties.
