In this paper, an attempt has been made to design an computational intelligence technique based expert system using Adaptive Neuro-Fuzzy Inference System (ANFIS) for predicting surface roughness in end milling of Inconel 718. Two different types of membership functions are adopted for analysis in ANFIS training and compared their differences regarding the accuracy rate of the surface roughness ...

Additive manufacturing of alloys has gained attention by industry as it provides economical production complex-configuration engine parts with fewer joining steps and greater geometric freedom. The creep behaviour additively manufactured (AM) Inconel 625 718 at 650 800 °C was compared that the wrought alloy after 24 hour long-term tests up to about one year. is precipitation strengthened while ...

Cold-rolled Inconel 718 with δ phase dispersion distribution was prepared and exhibited excellent superplasticity at 950°C a strain rate of 6 × 10−4 ~4 10−3 s−1. The elongation to failure 561% obtained 1 Superplastic deformation accelerates the recrystallization cold-rolled deformed microstructure, thus improving grain uniformity. dispersed promotes nucleation recrystallized grains pin boundari...

a high strength nickel chromium alloy (50cr-50ni-nb alloy), commonly referred to as in-657, is specifically used for components in furnaces which are fired by low grade fuel oils containing high levels of vanadium, sodium and sulphur. the purpose of this study is to experimentally investigatethe effect of machining parameters on machinability in turning of inconel 657. the considered parameters...

Erosion-corrosion can be a significant issue for engineering components used in the geothermal industry. This study assesses erosion-corrosion behaviour of wide range alloys which are various parts power plants. The evaluated materials comprised carbon steel, low-alloy three grades stainless steel together with Ni–Cr alloy (Inconel 625) and Ti–6Al–4V. Tests were conducted by utilising submerged...
