1. the method for crystal boundary slippage contribution in the quantitative measurment grained material superplastic deformation, it is characterized in that, process is as follows:

  • after the stretching sample surfaces is polished by machinery or chemical method, use nano-hardness tester to draw the cut that carves appropriate size at sample surfaces, cut mark line width is less than crystallite dimension, and mark line is parallel to draw direction;

    Carry out superplastic tension then, according to side-play amount, crystallite dimension and the stretcher strain amount of distortion back sample surfaces cut, the contribution of quantitative Analysis crystal boundary slippage in the grained material superplastic deformation.
