The temperature-depending change in controlling processes of high temperature deformation of in Ti-TiB composite

The rate-control processes depending on the temperature were investigated using TiB dispersed Ti matrix composite. The stress exponent was revealed to be 3.2 in the all temperature, while the activation energy changed from 515kJ/mol at higher temper to 81kJ/mol at lower temperature, suggesting the c...

Zusammenfassung:The rate-control processes depending on the temperature were investigated using TiB dispersed Ti matrix composite. The stress exponent was revealed to be 3.2 in the all temperature, while the activation energy changed from 515kJ/mol at higher temper to 81kJ/mol at lower temperature, suggesting the change in the rate-controlling phase from the ceramic phase (TiB)to the metallic phase (Ti).
