γ′ precipitation kinetics in the powder metallurgy superalloy N19 and influence of the precipitation latent heat

The N18 superalloy, powder metallurgy processed, is used for high-pressure turbine disks of the Snecma M88 engine and has been extensively studied. The size distribution of its γ′ precipitates was first modelled in the late 1980's using a binary alloy model [1]. The precipitation model has bee...
