PENG Jun , WANG Shijun , DONG Yuanchi , LIU Lixia , ZHOU Yun , CHEN Erbao

钢铁研究学报(英文版)

The solubility of nitrogen in the FeCVN system was measured at 1 708 K and the model of calculating activity (action concentration) of nitrogen (N) and vanadium (V) was derived according to the phase diagram and the coexistence theory of the metal melt structure. The solubility expression of nitr...

CHEN Erbao , WANG Shijun , DONG Yuanchi , WU Baoguo , ZHOU Yun

钢铁研究学报(英文版)

The saturated solubility of carbon and nitrogen in FeCN and FeCBN melts was measured experimentally at 1 485 ℃ to obtain the activity interaction coefficients between components in these melts. A new method was used to treat experimental results. Using thermodynamic derivation and calculation, ...
