摘要:
对Al〖CD*2〗TiO2-KBF4反应体系,采用熔体直接反应法制备了Al/TiB2复合材料.研究表明:采用合适的熔剂,可降低反应所需温度; 细小的TiB2 颗粒均匀地分布在铝基体上,当TiO2加入量为10%时,Al/TiB2复合材料的抗拉强度较基体提高了84.5%,而伸长率为12.7%; 重熔除气对复合材料组织分布影响不大,重熔除气后复合材料的抗拉强度较基体提高了98.9%
Abstract:
Al/TiB2 composites were fabricated by direct melt reaction with Al,TiO2 and KBF4.The reaction temperature can be decreased by adding flux.The fine TiB2 particles are homogeneous in the pure Al matrix. When the amount of TiO2 added is 10%wt, the strength of composite is higher than that of pure Al matrix by 84.5%,the elongation is 12.8%.The effect of remelting and degassing treatment on microstructure is little.However,the strength of composite is higher than that of pure Al matrix by 98.9%,the elongation is 10.8%.
