Modelisation of γ' precipitation during the quench of Ni base PM superalloy
Description
Nickel base alloys used in turbine disks have a good thermal mechanical resistance to precipitation of the ordered phase (Ni3Al) in the austenitic matrix γ. Precipitation of the intragranular γ' phase is studied on quenched samples by dilatometry and particles size distribution by TEM on the super alloy N18 (Co15.5Cr11.4Al4.3Ti4.3 Mo6.4). Experimental results are compared to a model based on nucleation and coalescence classical equations. (A.B.). 7 refs
