Thus, the structure of SHS product can be controlled.By means of combustion front quenching (CFQ) with copper wedge, the structure formation of TiB_2-xAl composites in the SHS process was discussed Key words： TiB_2-xAl composite    structure formation    self—propagating high temperature synthesis      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 傅正义 王为民 王浩 袁润章 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1994/V30/I20/373 1傅正义,袁润章,MunirZA．金属学报,1993;29:B3342MerzhanovAG．PureApplChem,1992;64:9413RogachevAS,MukasyanAS,MerzhanovAGDoklAkadNaukSSSR,1987;297:14254FuZY,WangWM,WangH,YuanRZ．PACRIMMeetingProceed,Hawaii,USA,1993:1425YuanRZ,FuZY,YangZL,MunirZA．JMaterSynthProcess,1993;1:153 [1] 刘长松; 刘永合 . 火焰喷涂合成TiC—Fe涂层的热力学分析[J]. 金属学报, 2000, 36(1): 62-66 .
