The results of a series of fatigue tests performed on two Co-Fe alloys at 150oC are reported. The ratio of the minimum to maximum load, R, in all tests was 0.1. Both materials behaved in a similar manner, with a fatigue limit (ie maximum stress to cause failure in 106 cycles) of 800 MPa (ie a stress range of 80 to 800 MPa). Following initiation, a short period of fatigue crack growth is followed by a fast fracture process. During fast fracture, the crack bifurcates; the bifurcation angles lie in the range 32o to 39o.

Abstract

The results of a series of fatigue tests performed on two Co-Fe alloys at 150oC are reported. The ratio of the minimum to maximum load, R, in all tests was 0.1. Both materials behaved in a similar manner, with a fatigue limit (ie maximum stress to cause failure in 106 cycles) of 800 MPa (ie a stress range of 80 to 800 MPa). Following initiation, a short period of fatigue crack growth is followed by a fast fracture process. During fast fracture, the crack bifurcates; the bifurcation angles lie in the range 32o to 39o.
