Case-hardened shaft-like components

Full titel:	Study on the high cycle fatigue evaluation of case-hardened shaft-like components
Duration:	02/2021 – 11/2021
Contributor:	Dipl.-Ing. Jakob Pogert (TU Dresden, IMM)
Financing:	Forschungsvereinigung Antriebstechnik (FVA)
Project partner:	Institut für Konstruktions- und Antriebstechnik (IKAT, TU Chemnitz)
Objective:	Improved utilization of the fatigue strength increasing effect of case hardening Differentiation of the influences of case hardening on the fatigue strength of shaft-like components instead of the use of generalizing KV factors
Approach:	Industry survey on common practice in case hardening and its consideration in the design process Literature search for heat treatment simulation, occurring damage mechanisms and existing fatigue strength concepts Creation of a database with test data of case-hardened components Recalculation of the literature data using nominal and local concepts
Results:	Compilation of efficient methods and essential input parameters for the simulation of case hardening processes Extensive test database of case-hardened shaft-like components Highlighting of suitable strength concepts
