Abstract
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 paper discusses a novel technique of microforming using friction stir technology and superplastic materials science. Superplastic Al-7075 and Al-Mg-Zr alloys have been microformed and characterized in this study.
