摘要:

AbstractThe effect of iron additions in the range 5–15 wt-%Fe inclusive on the microstructure and properties of a Ni–Cr–Mo–Si wear resistant alloy (Tribaloy T7 00) has been investigated. Iron additions were found to stabilise the hexagonal type structure of the Laves phase and to decrease the volume fraction of the primary Laves phase. These microstructural modifications reduced the hardness, slightly improved the toughness, and significantly enhanced the strength of the as cast alloys. Unlike T700, the alloys containing iron were not stable when heat treated at 700°C, and an increase in hardness was observed. The mechanical properties of T700 have been compared with those of the cobalt base Tribaloy alloys (T400 and T8 00).MST/1936
