| Abstract Scope |
Friction stir welding (FSW) has been proposed as a repair or mitigation process for austenitic stainless steel structures that experience chloride-induced corrosion. The feasibility of using FSW to repair such structures has been demonstrated, however limited information has been published regarding the effect of FSW process parameters on subsequent corrosion performance.
A study has been conducted to assess the effects of FSW process conditions on 304L austenitic stainless steel weldment properties. Simulations were performed to support thermal analysis of the FSW process using process parameters and material constitutive data. Optical and scanning electron microscopy were used to evaluate defect formation and microstructure evolution. Localized mechanical properties were assessed using indentation techniques. Corrosion performance was evaluated using electrochemical polarization and boiling magnesium chloride testing. The resulting corrosion behavior will be compared to as-received base material, furnace sensitized base material, and gas tungsten arc weldments. |
