Abstract：

|
Equal channel angular extrusion is an advanced technology that can refine the microstructure of materials.Nine sets of experiments were carried out for 2A50 aluminum alloys according to selected orthogonal experiment scheme during the single-path equal channel angular extrusion.Four main process parameters were given in the experiments,including channel angle,extrusion speed,lubrication condition and forming temperature.The influence sequence of the above four parameters on the grain-refining were obtained and the optimum scheme was put forward by a range analysis to grain size,which offered the scientific reference for multi-path experiments.
