@article{24572, abstract = {{ This experiment studied the strain parameters of rolling an aluminum matrix when wire netting is inserted between aluminum layers. During the experiment, two types of stainless steel fabric netting oriented parallel and diagonal to the rolling axis were placed between two aluminum strips and rolled. Multiple rolling processes were performed in which the temperature and pressure on the material were varied to produce bonding of matrix layers. During the study, the following main investigations were made: strain on areas of longitudinal and transverse cross sections of the composite was measured; stretching and ovalization of net wiring and changes in the net cell angles were determined; mechanical properties of composites along the rolling direction were tested. The main contradiction resulting from this experiment was as follows: the contact pressure required for the bonding of aluminum layers produces extreme tensile strain on the inserted net wires, reducing the mechanical properties of the reinforcing net and thus reducing properties of the entire composite. Optimal results in the longitudinal tension tests were achieved by using strips with diagonally oriented net-reinforcement. }}, author = {{Stolbchenko, Mykhailo and Makeieva, Hanna and Grydin, Olexandr and Frolov, Yaroslav and Schaper, Mirko}}, issn = {{1099-6362}}, journal = {{Journal of Sandwich Structures & Materials}}, number = {{6}}, pages = {{2009--2029}}, title = {{{Strain parameters at hot rolling of aluminum strips reinforced with steel netting}}}, doi = {{10.1177/1099636218792539}}, volume = {{22}}, year = {{2020}}, } @article{41520, author = {{Wu, Haoran and Bill, T. and Teng, Z.J. and Pramanik, Sudipta and Hoyer, Kay-Peter and Schaper, Mirko and Starke, Peter}}, issn = {{0921-5093}}, journal = {{Materials Science and Engineering: A}}, keywords = {{Mechanical Engineering, Mechanics of Materials, Condensed Matter Physics, General Materials Science}}, publisher = {{Elsevier BV}}, title = {{{Characterization of the fatigue behaviour for SAE 1045 steel without and with load-free sequences based on non-destructive, X-ray diffraction and transmission electron microscopic investigations}}}, doi = {{10.1016/j.msea.2020.139597}}, volume = {{794}}, year = {{2020}}, } @article{41521, author = {{Tillmann, Wolfgang and Lopes Dias, Nelson Filipe and Stangier, Dominic and Hagen, Leif and Schaper, Mirko and Hengsbach, Florian and Hoyer, Kay-Peter}}, issn = {{0257-8972}}, journal = {{Surface and Coatings Technology}}, keywords = {{Materials Chemistry, Surfaces, Coatings and Films, Surfaces and Interfaces, Condensed Matter Physics, General Chemistry}}, publisher = {{Elsevier BV}}, title = {{{Tribo-mechanical properties and adhesion behavior of DLC coatings sputtered onto 36NiCrMo16 produced by selective laser melting}}}, doi = {{10.1016/j.surfcoat.2020.125748}}, volume = {{394}}, year = {{2020}}, } @article{41522, author = {{Andreiev, Anatolii and Hoyer, Kay-Peter and Grydin, Olexandr and Frolov, Yaroslav and Schaper, Mirko}}, issn = {{0933-5137}}, journal = {{Materialwissenschaft und Werkstofftechnik}}, keywords = {{Mechanical Engineering, Mechanics of Materials, Condensed Matter Physics, General Materials Science}}, number = {{4}}, pages = {{517--530}}, publisher = {{Wiley}}, title = {{{Degradable silver‐based alloys}}}, doi = {{10.1002/mawe.201900191}}, volume = {{51}}, year = {{2020}}, } @article{24571, author = {{Stolbchenko, Mykhailo and Frolov, Yaroslav and Makeieva, Hanna and Grydin, Olexandr and Tershakovec, Michael A. and Schaper, Mirko}}, issn = {{1537-6494}}, journal = {{Mechanics of Advanced Materials and Structures}}, number = {{18}}, pages = {{1599--1608}}, title = {{{The mechanical properties of rolled wire-reinforced aluminum composites at different strain values}}}, doi = {{10.1080/15376494.2018.1520941}}, volume = {{27}}, year = {{2020}}, } @article{24254, author = {{Tillmann, Wolfgang and Hagen, Leif and Garthe, Kai-Uwe and Hoyer, Kay-Peter and Schaper, Mirko}}, issn = {{0933-5137}}, journal = {{Materialwissenschaft und Werkstofftechnik}}, pages = {{1452--1464}}, title = {{{Effect of substrate pre‐treatment on the low cycle fatigue performance of tungsten carbide‐cobalt coated additive manufactured 316 L substrates}}}, doi = {{10.1002/mawe.202000109}}, year = {{2020}}, } @article{24092, abstract = {{AbstractDifferent studies have been demonstrated that the surface integrity of substrate bulk materials to be coated has a significant impact on the adhesion of thermally sprayed coatings.
