Abstract

The strength and deformation characteristics of nitrogen contained TiC-Mo2C-Ni alloys were mainly studied at 1273K. The TiC-Mo2C-Ni, TiC0.7N0.3-Mo2C-Ni and TiC0.5N0.5-Mo2C-Ni alloys with different carbon and Mo2C contents were used as specimens. In usual bending tests, the deformation was suppressed and transverse-rupture strength increased with increasing nitrogen, carbon and Mo2C contents of the alloy. In creep bending tests, the suppression of deformation and an increase in creep strength were observed with increasing nitrogen and Mo2C contents of the alloy. The improvement of T.R.S. and creep strength was markedly observed, in particular, in the alloys containing nitrogen, and clearly related to the decreased grain size of carbonitride and the increased molybdenum content in binder it was phase, respectively.
