INCONEL alloy 783 was annealed and aged following the standard heat treatment procedure. One set of specimens was then isothermally exposed at 500 degrees C for 3000 h. Mechanical properties were measured at room temperature and 650 degrees C, and the results showed the prolonged exposure increased the strength and decreased elongation of alloy 783. The microstructures of as-produced and expose...

The development of additive technologies in the Russian Federation is constrained by lack indigenous base for production metal powders. SPbPU has developed, manufactured and introduced a plasma atomizer. It provides atomization powders alloys various chemical compositions. data on main technological parameters nickel alloy Inconel 718 titanium Ti-6A1-4V are presented paper. shown that optimizin...

In this work, the effect of ultrasonic nanocrystal surface modification (UNSM) treatment at room and high temperatures (RT HT) on high-frequency fatigue behavior Inconel 718 alloy fabricated by laser metal deposition (LMD) process was experimentally investigated. UNSM RT HT modified a morphology produced nanostructured layer with thickness approximately 120 140 µm, respectively. The roughness u...
