ABSTRACT

In this article, the thermal stability of TiC–Ti₃AlC₂ and TiC–Ti₃AlC composites during selective laser sintering/melting is studied. The phase composition evolution after laser processing is investigated and the structure of the obtained samples is also described. Samples were obtained by selective laser sintering/melting from mixtures of commercial powders and from a synthesised composite powder. It is possible to maintain most of the MAX-phase using the laser processing parameters described; in addition, the intermetallic phase is formed.

选择性激光处理过程中 TiC–Ti3AlC2 和 TiC–Ti3AlC 复合材料的热稳定性

摘要

在本文中，研究了 TiC–Ti ₃ AlC ₂和 TiC–Ti ₃ AlC 复合材料在选择性激光烧结/熔化过程中的热稳定性。研究了激光加工后的相组成演变，并描述了所得样品的结构。通过选择性激光烧结/熔化商业粉末的混合物和合成的复合粉末获得样品。使用描述的激光加工参数可以保持大部分 MAX 相位；此外，形成金属间相。
