Corrosion Control of Alloy 690 by Shot Peening and Electropolishing under Simulated Primary Water Condition of PWRs

<div>(a) Residual surface stress measured by XRD and (b) microhardness measured at the depth of 20 <i>μ</i>m from the surface of shot-peened and electropolished specimens. The specimen labels distinguish the different surface treatments: shot peening at 1 bar with angles of 30° (SP30), 45° (SP45), and 90° (SP90) and electropolishing after shot peening with angles of 45°(EP45) and 90° (EP90).</div>
