This Paper presents the welding parameterchr('39')s effect (forging pressure, welding time) on macrostructure and mechanical properties of friction welding valve steel HNV3 to Nimonic 80A super alloy. For this purpose, two rods with 20 mm diameters are prepared and with using different parameters (Increase forging pressure and welding time) by friction welding method are welded together. Tensil...

Abstract: In order to predict hot deformation behavior of superalloy nimonic 80A, a back-propagational artificial neural network (BP-ANN) and strain-dependent Arrhenius-type model were established based on the experimental data from isothermal compression tests on a Gleeble-3500 thermo-mechanical simulator at temperatures ranging of 1050–1250 ̋C, strain rates ranging of 0.01–10.0 s ́1. A comparis...
in the present study, the microstructural changes of a nickel based superalloy nimonic80a during a non-isothermal deformation were studied. therefore, microstructure evolutionduring hot side pressing test was predicted with combined methods of finite element analysis andprocessing map of the material. the predicted results were validated through experimentalmicrostructural studies. the results ...
