完全致密的微层压复合板组成的交替TiAl和TiB 2丰富的层已成功地制造使用辊压焊和反应退火，然后通过一个有效的致密化过程。与整体TiAl相比，富TiB 2层的引入显著细化了TiAl的片层组织，使TiB 2-TiAl复合材料具有更高的弹性模量、纳米硬度和高温强度。(C)2011 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Fully dense microlaminated composite sheets consisting of alternating TiAl and TiB2-rich layers have been successfully manufactured using roll bonding and reaction annealing followed by an effective densification process. Compared with monolithic TiAl, the introduction of TiB2-rich layers significantly refined the lamellar microstructure of TiAl and thus the unique microlaminated TiB2-TiAl composite sheet possesses a higher elastic modulus, nanohardness and high temperature strength.
