Ti-C-Ni-Mo系的自蔓燃-加压致密化

A Study of SHS-Pressing Process of Ti-C-Ni-Mo System

  • 摘要: 本工作基于对自蔓燃过程的分析,提出了自蔓燃-加压致密化过程中的可压制温度下限Tp和与之相应的可压制时间上限tp的概念,并建立了温度-时间-状态图。tp与燃烧持续时间tc之差为该工艺的控制参量-压制延迟时间t的上限值。据此时Ti-C-Ni-Mo系进行了研究.确定了最佳工艺参数,获得了近于完全致密的TiC-Ni-Mo合金。

     

    Abstract: Jn this work SHS-pressing process is studied. Concepts of compactable temperature minimum (Tp) and compactable time maximum (tp) are defined. A temperature-time-state diagram (TTSD) is presented. The upper limit of pressing time delay after combustion, τ, which is a control parameter of the SHS-pressing process, can be determined by tp-tc, where tc is combustion time. On the basis of the analysis, nearly full dense TiC-Ni-Mo alloy is synthesized.
