Corrosion Behaviour of NIMONIC-90 Alloy
Investigations were conducted on hot corrosion of Nickel base, NIMONIC-90 at 675°C and 725°C. The tests were carried out on small test coupons coated with a chemical containing Sodium sulphate and Sodium Vanadate which is representative of the corrosive deposit that usually forms during service in the coal fired boiler and the likes operating in marine atmospheres. Corrosion rates were measured...
متن کاملStudy the Profile Shape and Mechanical Properties of Bonded Joint HNV3 to Nimonic 80A Superalloy with Inertia Friction Welding Method
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...

متن کاملPrediction of the Hot Compressive Deformation Behavior for Superalloy Nimonic 80A by BP-ANN Model
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...
متن کاملDevelopment of High Performance Machining Techniques through Data Mining and Interpretation: Modelling for Temperature Distribution of Nimonic 90
Nickel based super alloys are fast gaining relevance and importance in the aerospace and steam power industries, as they have high strength to weight ratio, and exhibit superior mechanical properties. In addition, they possess high resistance at high temperatures; maintaining their resistance to corrosion, thermal shock, creep and erosion at elevated temperatures. Nickel based alloys contain a ...
