Inconel®718 is a well-known nickel-based super-alloy used for high-temperature applications after thermomechanical processes followed by heat treatments. This work describes the evolution of microstructure and stresses during hot deformation prototype alloy named IN718WP produced powder metallurgy with similar chemical composition to matrix Inconel®718. Compression tests were performed simulato...

Abstract. This article presents comparison of laser metal deposition methods. The main methods presented in this work assume use additional materials a form powder and filler wire. An important differences problem with two different was presented. A abovementioned Inconel 625 alloy shown. Microstructure analysis performed on manufactured specimens Differences mechanism for both were

Thin films of ceramic materials like alumina and silicon carbide are deposited on Inconel substrate by pulsed laser deposition technique using Q-switched Nd: YAG laser. Deposited films are characterized using UV-visible spectrophotometry and X-ray diffraction. Composite microhardness of ceramic coated Inconel system is measured using Knoop indenter and its film hardness is separated using a mat...

Recently, efforts have been made to develop the use of dissimilar metal welding in industrial components. Pressurized water reactors (PWR) nuclear power plants frequently (DMW) their primary systems (NPP). The selection combination stainless steel and low alloy is adjusted working conditions work high-temperature environments. Nickel-based Inconel 82/182 used as a weld filler GTAW method joinin...

Abstract: The investigation is carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials: the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steel 310. This paper describes the effects of aging treatment on the joint. The compara...
