Abstract

Cyclic life of gas engine parts depends on various technological and operational factors including cycle asymmetry. Low cycle fatigue tests for EI698VD alloy with various strain ratios under 20 and 550 °С temperature were conducted. Based on experimental results low cycle fatigue model was obtained.
