Precipitation behavior of γ′ phase in P/M superalloy Udimet720Li

Precipitation behavior of γ′ phase in P/M superalloy Udimet720Li

P/M superalloy Udimet720Li specimens were solutioned and quenched at the different cooling rates in gas quenching furnace, following by the double aging treatment. The microstructures and elevated temperature tensile properties at 650 ℃ were investigated, and the γ′ precipitation behavior and streng...
