Abstract

AlMgB-TiB composite materials were fabricated by self-propagating high-temperature synthesis (SHS) followed by spark plasma sintering of the obtained SHS products. It was found that, during the SHS, the AlMgB phase is formed at a donor (Ti + 2B) to acceptor (AlMg-B) mass ratio of 3:7 and 4:6, respectively. The specimen sintered from the SHS powder with the donor:acceptor mass ratio of 5:5 at a temperature of 1470 °C has a uniform skeletal structure. The average hardness of the obtained specimen is 30.1 GPa.

摘要

通过自蔓延高温合成（SHS）制备AlMgB-TiB复合材料，然后对所得SHS产物进行放电等离子烧结。结果发现，在SHS过程中，AlMgB相分别在供体（Ti + 2B）与受体（AlMg-B）质量比为3:7和4:6时形成。由供体:受体质量比为5:5的SHS粉末在1470℃烧结而成的试样具有均匀的骨架结构。所得试样的平均硬度为30.1 GPa。
