Referat pt. “Investigation of deformation mechanisms in hexagonal metals using EBSD, microstructure and texture analysis” wygłosi dr inż. Jakub Kawałko (ACMiN AGH).

Streszczenie:

From resorbable coronary stents to compressor discs in jet engines, hexagonal metals have as wide range of potential applications as the range of their properties.

Zinc alloys can become brittle or superplastic, while titanium can withstand high pressures and temperature, while being corrosion resistant. In both cases plastic deformation techniques are important processes allowing to create desired shapes as well as tailor the macroscopic properties by modifying microstructure and texture of those materials.

In this talk I will explore the underlying mechanisms governing the microstructural changes during plastic deformation, and affect the final mechanical properties.

In the first part of my talk I will give a brief introduction to microstructure and texture analysis using EBSD technique in SEM, as well as an overview of plasticity of hexagonal metals. After the introduction I will give examples of application of EBSD microstructure and texture analysis to investigate titanium and zinc alloys processed by different severe plastid deformation methods, application of process with strain path change, and finally an example of deformation mechanisms analysis using SEM in-situ tensile testing.
