Damage Mechanisms at Various Strain Rates and Temperatures in Az31B Magnesium Alloy Conference Paper uri icon

abstract

  • The effects of temperature and strain rate on the fracture and damage of AZ31B were investigated. Special attention was paid to the work of fracture (Wf), which was found to exhibit a maximum at a specific strain rate and a specific temperature. Microstructural investigations at conditions of interest showed the marked effect of strain rate on the preferred sites of damage nucleation and development of micro-voids and micro-cracks. The findings point to the need for models for rate- and temperature-dependent damage in magnesium alloys.
