In this work, a new surface treatment process known as flow peening (GOV) already developed by combining the advantages of abrasive flow machining (AFM) and shot peening methods such as surface finishing and residual compressive stress generation respectively was applied experimentally for Inconel 718.

The results show that the hydrogen deoxidation mainly happens with the gas state of H<sub>2</sub> since there are more reactive sites of H atoms in the gas bubble compared to the dissolved H.
