| 中文摘要 | Thermal stability of primary MC carbide and M(CN) carbonitride in K452 and K446 alloys is investigated. In K452 alloy, primary MC is very unstable relative to M(CN) for the former contains a higher content of the weakeners (Wand Mo) than the latter. The ratios of element contents (at.%) (W + Mo)/Cr, (W + Mo)/(Ti + Nb) and Nb/Ti are three important parameters, which together determine the thermal stability of primary MC. Also, primary MC degeneration plays an important role in the microstructural instability of K452 and K446 alloys. (c) 2007 Elsevier B.V. All rights reserved. |
