In the advanced stage of non-isothermal sintering, vacancy clusters are present as prevailing type of defects. Their concentration considerably decreases at further temperature increase, and it can be concluded that thermally activated conversion of multiple vacancies into climbable dislocations takes place. Hence, in conformity with recent experiments, coincidence of intensive material transport ($ dot varepsilon $ e-maximum) and decrease of defect concentration (recovery) can be understood. |
