Analysis of Crack Propagation, Determination of Dynamic Strength and Metallographic Examination/Hardness Test using the Example of a 25 CrMo 4 Monobloc Tubular Shaft

摘要

After performing an alternating load test for several monobloc tubular shafts (so called MTS) a fractographical evaluation with sub-sequent metallographic examination as well as a review of the heat treatment according to drawing requirements were carried out on a test component which had reached the lowest number of cycles.
