| Description: |
• Develop the technological basis for friction stir welding and processing (FSW/P) of advanced high-strength and lightweight materials for the automotive industry. • Gain fundamental understanding of the relationships between workpiece and tool material properties during FSW/P. • Characterize the mechanical properties and microstructures of joints. • Correlate the proprieties and microstructures produced by FSW/P to the process conditions. Approach • Conduct experimental welding and processing tests on advanced materials using the state-of-the-art FSW/P process development system. • For particular workpiece materials, select the tool material based primarily on high-temperature strength, wear resistance, and chemical compatibility. • Evaluate mechanical properties and their correlation with microstructures produced by FSW/P. • Develop predictive modeling capability to study the properties as a function of process conditions. Accomplishments • Completed a study on friction stir processing to improve properties of cast magnesium alloy AM60B. • Demonstrated the feasibility of friction stir spot welding of advanced high-strength steels. • Conducted friction stir processing of steel 1080 for wear resistance improvement. • Initiated friction stir processing of Ti. |
