DP2794 Rene 88DT Alloy Powder

Rene 88DT Alloy Powder Description

Rene 88DT Alloy Powder was developed to be more damage tolerant than Rene’ 95, hence the DT designation, while offering improved creep strength and fatigue crack growth resistance. The production alloy is always processed through the powder metallurgy route. The standard heat treatment consists of: a super-solvus solution of 1.0 hr at 1150°C (2100), followed by a delayed oil quench, and aging for 8.0 hr at 760°C (14OO). Its main structural characteristics are thus a fine grain size, achieved through PM consolidation, and a duplex distribution of, the coarser forming on cooling from the super solvus solution, the finer predominantly on aging. Rene 88DT is used in disk applications in advanced General Electric Co. engines.
