%X The high chromium white iron with equiaxed primary structure was extruded at semisolid state. The liquid phase was squeezed out by pressure. After solidification, the volume percentage of the eutectic structure increases gradually from the center to the perimeter. Test shows that the extrusion temperatures have great effect on the structure of the extruded sample. The compact toughness at the center of the sample and the wear resistance at the perimeter of the sample are improved.
