Since powder metallurgy(PM)turbine disks hav ehigh yield strength and excellent property of resistance to fatigue and creep
they have been applied broadly in the most advanced engines at pressent in the world.As the thrust-to-weight ratio increases
the PM turbine disks will be developed in our country.At first
this paper makes a general survey of the application of the PM turbine disks.Then a review is made for the material properties
fatigue life
crack propagation
and stress analysis of PM turbine disks.Finally
so meresearch projects of the PM turbine disks fatigue life
which should be conducted in our country
are suggested.
