Abstract

Abstract:

There are differences in the mechanical properties of magnesium alloys at different loading rates， in order to explore the relationship between cyclic frequency and ratcheting strain， cyclic experiments under stress control were carried out on extruded AZ31B magnesium alloys to study the effect of frequency on the ratcheting strain of magnesium alloys and its evolution process. The cyclic deformation process of magnesium alloys at frequencies of 1.0， 2.0， 5.0 Hz are discussed respectively. The results show that there is an obvious ratcheting effect during cyclic deformation of extruded AZ31B magnesium alloys， and the relationship between the ratcheting strain and frequency under the same average stress is not monotonic. The results also show that value of the ratcheting strain at 5.0 Hz is in the range between 1.0 Hz and 2.0 Hz， which is due to the fact that when the frequency is 1.0 Hz versus 2.0 Hz， the stresses act for a longer period of time under a cyclic cycle at a lower frequency， so the value of the ratcheting strain formed at 1.0 Hz is greater than at 2.0 Hz. However， at a frequency of 5.0 Hz， the twinning-de-twinning mechanism is more predominant relative to 1.0 Hz and 2.0 Hz， and there is a lower hardening rate in the cycle， so the ratcheting strain values are greater than at 2.0 Hz. At different frequencies， the ratcheting strain increases rapidly in the pre-cycle period and stabilizes after a certain number of cycles.

Key words: frequency, ratcheting behavior, fatigue, stress-controlled, twinning mechanism
