| Abstract Scope |
Commercially available Ni-based superalloys, originally designed for aerospace applications, have been considered for use in next generation power plants. Nimonic 105 is a candidate for use as bolts and blades, and the alloy could potentially be used for other components. The specified carbon concentration calls for a maximum of 0.17 wt.% with nominal values on the higher end. In this work, the effect of carbon was investigated using two formulations with 0.15 and 0.03 wt.% carbon manufactured using a conventional cast/wrought processing route. The high carbon version revealed 400% increase in MC carbides density with the particles being 55% larger than in the low carbon version. The carbides were responsible for facilitating breaking the cast structure during the early steps of forging. The low carbon alloy showed significant surface cracking. The mechanical performance of the two alloys will be presented and discussed with regards to tensile and creep behavior. |
