半固态挤压成形,微观结构发生了显著的变化,针片状共晶硅相成小颗粒,大尺寸阶段也是明显的破碎炼油主要硅圆角和形状、分布更均匀。的过程中形成了高于挤压显微组织细化往往更明显。
Semi-solid extrusion, the microstructure of a significant change occurred, needle-like eutectic silicon into small particles, the large-size stage is also a major crushing refinery main round and shape of silicon, more evenly distributed. The formation of extruded microstructures is often more pronounced than that of extruded microstructures.
