| Abstract: | The variation of two types of residual stresses, i. e., residual surface stress and indentation residual stress, with annealing temperature in Knoop indented bending beam made of ceramics is studied. It is shown that the residual surface stress generated by machine grinding can be eliminated completely by annealing process, while the residual stress due to indentation can be reduced partly only. Annealing seems not to be an effective method to eliminate the effect of residual stress due to indentation, because material properties will be changed after annealing beyond a specified limit of temperatures. |
