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.
