The fracture hardness of Inconel alloy 625 in the cast and welded conditions has been evaluated as a part of complete properties of alloy for advanced steam turbine applications. The fracture properties of solution treated alloy vary because of prolong aging at 650oC, with metallurgical precipitation causing changes to critical toughness and fracture resistance profiles. … Continue reading Evaluation of Fracture toughness properties of Inconel grade 625

With the variety of different thermal spraying processes, a wide range of gases is used majorly in applications for fuel gases and oxygen. Different hydrocarbons, particularly acetylene and hydrogen are used. Besides the fuel characteristics, aspects of the gas supply system are also crucial. Flame spraying guns can commonly be used for different fuel gases … Continue reading How Arc spray coating improves the function of application components

Wrought weldable nickel-chromium alloy Inconel 718 is fit for service at moderate temperature about 1300oF. However not as strong as other super alloys that service from 1500oF to 1800oF, its combination of good mechanical and fabrication characteristics at high and low temperature has earned it an essential role in various aerospace equipments. It is used … Continue reading Why aging of Nickel-Chromium alloy Inconel 718 is necessary?

                        Nitric Acid (HNO3) Chromium is a major alloying element for corrosion resistance in HNO3 conditions because it quickly develops a passive layer in these conditions. So alloys containing higher chromium content offer better performance in HNO3. In these conditions, the high chromium alloys … Continue reading Corrosion behavior of nickel based alloys in industrial acidic media

Intergranular Corrosion Intergranular corrosion is a localized form of attack occurring at the grain boundaries of a metallic materials with nominal or no effect on the grains. It affects metal’s strength and ductility. This type of corrosion occurs quickly affecting the metal deeply and damaging it. While using austenitic stainless steels, the corrosion is caused … Continue reading Intergranular and Galvanic Corrosion of Materials
