Weld evaluation of eutectic high-entropy alloy and austenitic steel formed by EBW

Original language description

AlCoCrFeNi2.1 alloy belongs to a group of materials called eutectic high-entropy alloys (EHEAs). These have gained attention due to the fact that there is no so-called “strength ductility trade-off”. At the same time, the material properties are stable over a wide temperature range due to the high entropy state of the eutectic structure. The generally good castability of eutectic alloys, which prevents segregation of the major chemical elements and precipitation of new phases, also extends the possibilities for future applications. Based on the above, AlCoCrFeNi2.1 alloy could be applied in critical structural locations subjected to severe conditions in terms of elevated temperatures and mechanical stresses. Alloy could replace, for example, austenitic steels with high ductility but lower tensile strength values. In order to make full use of a given material, its behaviour must be verified in bonding technologies with commercially used materials. Therefore, the following research deals with heterogeneous weld joints of AlCoCrFeNi2.1 with austenitic steel EN 1.4571 formed by electron beam welding. The evaluation of the weld consisted of observation of the resulting microstructure, determination of the chemical concentration of the elements in the fusion zone, phase analysis followed by mechanical properties testing in the form of Vickers hardness test and tensile test.
