Thermal ageing for up to 1000 h at 600鈥 800 掳C was used to study the long-range ordering behaviour to Ni 4 Mo and related ordered phases in selected Ni-Mo based alloys with varying Fe and Cr contents, and the corresponding effects on mechanical properties. Analytical electron microscopy ...
Transition from short-range to long-range order in Ni4MoTransmission electron microscopic observation was made on the transition from short-range to long-range order in Ni4Mo. The transition was found to take place by nucleation and growth of long-range-ordered domains in the short-range-...
Effect of Minor Alloying Elements (C, Ni, Cr, Mo) on the Long-Term Corrosion Behaviors of Ultrahigh-Strength Automotive Steel Sheet in Neutral Aqueous Envi... This study examined the effects of minor alloying elements (C, Ni, Cr, and Mo) on the long-term corrosion behaviors of ultrahigh-...
The present work demonstrates that seawater corrosion potential ennoblement can persist during long-term immersion exposures for several corrosion resistant Ni-Cr-Mo alloys. The present study considers the implications of long-term and short-term seawater ennoblement on Alloy 625 (UNS N06625), Allo...
