TiAl-based alloys, as the most promising lightweight structural materials exhibit excellent mechanical properties and good oxidation resistance at 700–900 °C [1].
Fatigue testing is a specialised form of mechanical testing that is performed by applying cyclic loading to a coupon or structure. These tests are used either to generate fatigue life and crack growth data, identify critical locations or demonstrate the safety of a structure that may be susceptible to fatigue.These machines are used to test the fatigue life of small wires and cables. The rotary beam method to induces a cyclic strain at high frequency, reducing the testing time compared with other methods. Model variations provide for a very wide range of achievable test strain values. The machine captures the number of strain cycles
