| 英文摘要 | The effect of silicon addition on the precipitation and decomposition behaviors of M6C carbide in a Ni-Mo-Cr based superalloy and the tensile properties of this alloy have been investigated. Silicon increases the amount of undissolved M6C carbide particles obviously in Ni-Mo-Cr superalloy. Composition analyses reveal that primary M6C carbides in the standard heat are highly enriched in silicon. The addition of silicon widens the temperature range of M6C carbide existence to 1335 degrees C, while the M6C carbide in non-silicon heat was completely decomposed when heated to 1260 degrees C. According to the calculation results using Thermal-calc software, the Gibbs free energy of M6C carbide decreases with the silicon content, and the silicon-riched M6C carbide is more stable than that in non-silicon heat samples. In tensile tests, it is found that silicon-rich M6C carbide particles act as cracking origin sites, and further give rise to the degradation of the high temperature tensile properties of standard heat samples as compared to non-silicon heat ones.
