Friction stir process
"The last decade has witnessed a strong technological thrust for manufacturing of micro-components. Polymers and ceramics have been replicated using micromolds, and are commercially used to produce microcomponents in large numbers. On the other hand, for demanding microsystems applications, metals are an attractive choice, for their mechanical and wear properties. Microforming of superplastic alloys has been investigated with good success. This thesis presents a novel technique of microforming using friction stir technology and superplastic materials science. The friction stir microforming process design, microdie design and experimental procedure are detailed. Superplastic Al-7075 and Al-Mg-Zr alloys have been microformed and characterized in this study. Comparison of formability and micro structure of superplastic Al-7075 versus non-superplastic Al-7075 alloy is also presented. Results of a conventional microforging experiment are compared with friction stir microforming. Finally, key issues pertaining to friction stir microforming are brought up and recommendations are made for future work in this field"--Abstract, page iii.
