Evolution of grain boundary and texture in as-forged Ti–45Al–9Nb–Y alloy during tensile test at different temperature
چکیده انگلیسی

Grain boundary and texture evolution of as-forged Ti–45Al–9Nb–Y alloy have been investigated during tensile test between room temperature (RT) and 900 °C. The volume of high angle grain boundaries (HAGBs) increases a certain extent during RT tensile strain, but the volume of low angle grain boundaries (LAGBs) increases with the temperature rising in the range of 800 °C–900 °C. Up to 850 °C, The texture, presented in inverse pole figures, contains deformation textures, i.e. <110>, <111>, <112> and <001>. While the temperature rises to 900 °C, dynamic recrystallization and plastic deformation occur simultaneously instead of single plastic deformation progress at the temperature below 900 °C and a new recrystallization texture of <100> replaces the deformation textures.
