Hastelloy C22 and Inconel 600 and 601 alloys specimens were cyclically deformed. Specimens were sectioned and investigated. Results indicated that the grain structure of Hastelloy C22 revealed planar slip bands, whereas Inconel 600 and 601 showed slip bands having triangular ribbon morphology. The triangular ribbon bands were more distinct in Inconel 601 than in Inconel 600.

this study is focused on investigating the parameters of laser percussion drilling process of nickel-base super alloy inconel 718 with thickness of 1 mm. fiber laser with the power of 500 watts was used as the laser source. laser pulse frequency, duty cycle, laser power, focal point position, were assumed as the laser drilling process variables. the hole geometry features, i.e. entrance hole di...

Among the several non-conventional processes, electrical discharge machining (EDM) is the most widely and successfully applied for the machining of conductive parts. In this technique, the tool has no mechanical contact with the work piece and also the hardness of work piece has no effect on the machining pace. Hence, this technique could be employed to machine hard materials such as super allo...

INCONEL 706 is a high-strength nickel-based super alloy that commonly used in high-temperature applications such as gas turbines and nuclear reactors. In this study, the hot tensile properties of Inconel were investigated to better understand material's behavior under high-stress conditions. Tensile tests conducted at temperatures ranging from 740°, 860°, 940°, 1020°1080°and strain rates 0.001/...

This article provides a materials selection methodology applicable to lightweight actively cooled panels, particularly suitable for the most demanding aerospace applications. The key ingredient is the development of a code that can be used to establish the capabilities and deficiencies of existing panel designs and direct the development of advanced materials. The code is illustrated for a fuel...

The demand for components made from high performance materials like titanium or nickel-based alloys as well as strain-hardening stainless steel is steadily increasing. However, conventional forming operations conducted on these materials are generally very laborious and time-consuming. This is where the limitations of metal spinning also become apparent. Using a laser to apply heat localized to...

Hard turning is the latest technology and is used to turn hard materials by using cutting tools like CBN and PCBN. Certain hard materials like titanium, Inconel and stainless steel are pronounced as difficult to cut materials. The superior cutting tools effectively machine such hard materials and produces desirable surface roughness with less tool wear. The present research was carried on hard ...
