This report concerns the programme to establish a set of high temperature low cycle fatigue (LCF) data representative of accepted testing practice and to define a standard test procedure. The European and Japanese laboratories which participated each used its normal test methods, but under specified test conditions. Three classes of alloy were selected for testing, according to their cyclic strain behaviour: (i) strain-hardening - AISI 316L steel at 550 C (21 data sets); (ii) strain-softening - either 9CrMo steel (16 data sets), or IN718 alloy (12 data sets), at 550 C; (iii) stable - Nimonic 101 at 850 C (12 data sets). The results of the tests are reported. The data obtained are compared graphically and assessed on the basis of the relative position of the data sets from individual laboratories within the overall scatter band of all the data. Conclusions are drawn and recommendations given.
