Microstructure modification for improved mechanical properties in A356 Al using friction stir processing
"This research work was initiated to develop FSP as a tool to locally modify the microstructures in various aluminum alloys and study the changes in the mechanical properties of the modified regions...This dissertation work is divided into four papers. The first paper attempts to understand the microstructure evolution during FSP of A356. The second paper examines the influence of FSP on high cycle fatigue behavior of A356. The third paper examines the influence of processing parameters on process loads, temperature, microstructure and the corresponding static mechanical properties. The fourth and final paper deals with crack growth rates in FSP A356"--Research Objective, pages 29-30.
