Abstract

Microstructure and low cycle-high temperature fatigue properties of NIMONIC 105 SUPERALLOYs with and without B and Zr is investigated in this article. Fully reversed strain-controlled tests were performed at 750°C, R=0 and strain rate of 3×10-3 s-1. The results show that Zr cause to ZrC formation at the grain boundaries and grain interior. Also Zr is reduced the grain size of the alloys. The carbides at the absence of Zr is of the type of (Cr, Mo)23C6 at the grain boundaries. The g’ size decreased by B additions to the alloys and the number of twins increased. 0.013wt% B improves low cycle-high temperature fatigue of the alloy. At the presence of B, fracture is of the types of intragranular and intergranular but by addition of 0.16wt% Zr the only fracture type is intragranular. Hard and none coherent MC type precipitates by Zr addition are the initiation place for micrcraking and the cause of fatigue life reduction.
