Modification of Co-Cr alloys to optimize additively welded microstructures and subsequent surface finishing

Autor: Antonia Eissel, Lorenz Engelking, Kai Treutler, Volker Wesling, Dirk Schröpfer, Thomas Kannengießer

Cobalt chromium alloys are often used in turbine and plant construction. This is based on their high thermal and mechanical stress resistance as well as their high wear resistance to corrosive and abrasive loads. However, cobalt is a cost-intensive m

Influence of modern machining processes on the surface integrity of high-entropy alloys

Autor: Dirk Schröpfer, Andreas Börner, Michael Rhode, Tim Richter

Publikováno v: IOP Conference Series: Materials Science and Engineering. 882:012016

High Entropy Alloys (HEAs) are a recent class of materials. In contrast to conventional alloys, HEAs consist of five alloying elements in equiatomic equilibrium. The high entropy effect is due, among other things, to the increased configuration entro

Influence of Heat Control on Welding Stresses in Multilayer-Component Welds of High-Strength Steel S960QL

Autor: Arne Kromm, Thomas Kannengiesser, Dirk Schröpfer

Publikováno v: Advanced Materials Research. 996:475-480

Today high-strength structural steels (yield strength ≥ 960 MPa) are increasingly applied. Therefore, weldments have to achieve equal strength. Yet, high residual stresses in those welds diminish the components safety. Especially high restraint int

Welding Residual Stress Distribution of Quenched and Tempered and Thermo-Mechanically Hot Rolled High Strength Steels

Autor: Thomas Schaupp, Thomas Kannengiesser, Arne Kromm, Dirk Schröpfer

Publikováno v: Advanced Materials Research. 996:457-462

Beside quenched and tempered (QT) high strength steels advanced technologies in steel manufacturing provide steels produced by the thermo-mechanical controlled process (TMCP) with yield strength of 960 MPa. These steels differ in the carbon and micro

From the Field to the Lab: Real Scale Assessment of Stresses in Welded Components

Autor: Dirk Schröpfer, Andreas Hannemann, Thomas Kannengiesser, Jonny Dixneit, Arne Kromm, Thomas Lausch

Publikováno v: Materials Performance and Characterization. 7:20170103

Residual stresses are crucial when assessing the performance of welded components. The present work deals with the possibilities of transferring the real-life boundary conditions of welding, which influence the residual stress, into the laboratory. T
