Abstract
The microstructure and hardness evolution of ERNiCrMo-3 deposited metal exposed at 750 °C have been investigated in this study. In the as-welded sample, the MC/TiN, Laves, and \( \delta \) phase can be found in the interdendritic regions, but only MC/TiN phase located at the grain boundaries. After the aging treatment, additional M23C6 carbides can be observed at the grain boundaries and nano-sized γ″ particles formed in the matrix. Both \( \delta \) phase and γ″ phase were found to possess one certain orientation relationship and semi-coherent interfaces with the matrix, which are responsible for the hardening of the deposited metal during the initial stage of aging. With the increase in aging time from 10 to 100 h, γ″ phase coarsens, but needle-like \( \delta \) phase becomes denser and longer, which contributes to the successive hardening.
