Measurement of γ'precipitates in nimonic PE16

Creators

Description

γ' precipitates in Nimonic PE16 have been examined using bright and dark field imaging techniques in an electron microscope. The validity of these techniques to determine mean precipitate diameters, precipitate density and volume fraction is discussed. It is concluded that bright field imaging techniques are sufficiently accurate to measure γ' precipitate diameters but it is essential to use dark field imaging techniques to determine γ' precipitate density or volume fraction.
