【摘要】

：

采用超声波辅助搅拌铸造的方法，成功制备了碳化硅质量分数为20％的大尺寸镁基复合材料，铸锭的质量大约为21千克.与基体合金相比，复合材料的力学性能得到了明显提升.在复合材料的不同位置，碳化硅颗粒均匀分布，各部位的含量相同.但是，从微观结构上来看，颗粒沿着晶界呈项链状分布.在热挤压过程中，尽管部分碳化硅颗粒结构受损，但是显著改善了碳化硅颗粒在复合材料内的分布，同时进一步提高了材料的力学性能.T6处理材

木材液化物水洗不溶物的制备及其性能研究

本论文对术材液化物水洗不溶微球进行了研究，利用不同洗涤工艺可制备木材液化物微球，并对其微观结构、热性能、化学结构进行了探讨和分析。结果表明，水浴温度70℃的中性水水洗工艺制备的杉木、杨木液化物微球在数量、球形度、表面致密性等方面均优于常温水水洗工艺和盐酸水溶液洗涤工艺，前者的灰份含量则低于后两者。
