Microstructure of Haynes® 282® Superalloy after Vacuum Induction Melting and Investment Casting of Thin-Walled Components
The aim of this work was to characterize the microstructure of the as-cast Haynes® 282® alloy. Observations and analyses were carried out using techniques such as X-ray diffraction (XRD), light microscopy (LM), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray spectroscopy (EDS), wave length dispersive X-ray spectroscopy (WDS), auger electron spectroscopy (AES) a...
متن کاملImpact Deformation and Fracture Behaviour of Cobalt-Based Haynes 188 Superalloy
The impact deformation and fracture behaviour of cobalt-based Haynes 188 superalloy are investigated by means of a split Hopkinson pressure bar. Impact tests are performed at strain rates ranging from 1×103 s-1 to 5×103 s-1 and temperatures between 25°C and 800°C. The experimental results indicate that the flow response and fracture characteristics of cobalt-based Haynes 188 superalloy are sign...
متن کاملExamining of Tool Wear in Cryogenic Machining of Cobalt-Based Haynes 25 Superalloy
Haynes 25 alloy (also known as L-605 alloy) is cobalt based super alloy which has widely applications such as aerospace industry, turbine and furnace parts, power generators and heat exchangers and petroleum refining components due to its excellent characteristics. However, the workability of this alloy is more difficult compared to normal steels or even stainless. In present work, an experimen...
متن کاملTemperature Dependence of Residual Stress in Titanium Nitride Coatings on Haynes 188 Superalloy
Residual stresses in TiN coatings deposited by a reactive ion process on Haynes 188 superalloy, for potential application in jet engines, were determined over the temperature range from 30–800 °C, using high temperature X-ray diffraction. In the as-coated condition the TiN films have a pronounced [111] orientation texture and a compressive room temperature stress of -10.5 GPa. After heating for...
