The cast and wrought nickel superalloy Rene 65 has been recently introduced to provide a gamma prime strengthened alloy with high performance at temperatures exceeding 700 °C at a lower cost than powder metallurgy alloys. While similar in chemistry to the PM alloy Rene 88DT, Rene 65 is typically used in a subsolvus form with finer grain size and a very different gamma prime distribution. This study provides an overview of the structure of Rene 65, and the effects high temperature exposures over long times have on the structure and mechanical properties of the alloy.
