Witryna14 kwi 2024 · It was determined from the studies in the literature that the friction coefficient between the metal impactor and the composite material was applied as 0.3 … WitrynaDuring the casting cooling process or the forging process, austenitic stainless steel will remain at around 800 °C for some time. During this period, precipitate particle behaviors in austenitic stainless steel (containing ferrite) will cause a reduction in ductility, which can lead to material cracking. In this study, the effects of aging at 800 °C on the …
