To enable the application of additive manufacturing in fatigue critical components, the fatigue properties of additively manufactured metals must be evaluated. Preferably with efficient methods that save time and costs.
This contribution will show the efficiency of physical measurement techniques. The measured physical values show a pronounced interrelation with the underlying fatigue processes and represent the actual fatigue state. In addition to conventional stress-strain-measurements, the suitability of of high-precision temperature and electrical resistance measurements in combination with load increase tests will be shown.
The cyclic indentation test procedure PhyBaL-CHT requires only a planar material surface of 2 mm˛ and 2 mm thickness. Therefore it is applicable to estimate the cyclic hardening potential either the test material is limited or for process parameter studies.
