"Friction stir welding adalah proses pengelasan solid-state thermomechanical. Sejak penemuannya di TWI pada tahun 1991, proses ini telah diaplikasikan dalam berbagai industri seperti otomotif, aerospace, perkapalan, dan elektronik. Skripsi ini menginvestigasi efek parameter pengelasan micro friction stir welding terhadap temperatur pada aluminium paduan A1100 dengan ketebalan 400 μm. Pada proses pengelasan micro friction stir welding, panas yang dihasilkan gesekan dan efek pengadukan oleh rotasi tool dapat mengakibatkan perubahan pada mikrostruktur dan berakibat pada perubahan sifat mekanik. Ada tiga parameter pengelasan yang dipertimbangkan dalam skripsi ini yaitu, plunge speed, dwell time pertama, dan dwell time kedua. Temperatur aluminium pada saat proses pengelasan FSW diukur. Hasil yang diperoleh menunjukkan bahwa dwell time kedua memiliki pengaruh besar terhadap temperatur lasan sedangkan dwell time pertama kurang berpengaruh.

Friction stir welding is a solid-state thermomechanical welding process. Since its invention by TWI in 1991, it has found its application in industries such as automotives, aerospace, shipbuilding, and electronics. In this paper, the effects of welding parameters on the temperature of micro friction stir welding in thin sheet aluminum A1100 alloy with a thickness of 400 μm were investigated. In a micro friction stir welding process, the heat generated by friction and the mixing effect of the tool rotation can cause changes to the microstructure thus changing its mechanical properties. Three welding parameters were considered, plunge speed, first dwell time and second dwell time. The temperature during FSW were measured. The results obtained showed that the second dwell time was a dominant factor affecting the temperature of the weld whereas the first dwell time has very little effect on temperature."

"Materials are the stuff of design. From the very beginning of human history, materials have been taken from the natural world and shaped, modified, and adapted for everything from primitive tools to modern electronics. This renowned book by noted materials engineering author Mike Ashby and industrial designer Kara Johnson explores the role of materials and materials processing in product design, with a particular emphasis on creating both desired aesthetics and functionality. The new edition features even more of the highly useful "materials profiles" that give critical design, processing, performance and applications criteria for each material in question. The reader will find information ranging from the generic and commercial names of each material, its physical and mechanical properties, its chemical properties, its common uses, how it is typically made and processed, and even its average price. And with improved photographs and drawings, the reader is taken even more closely to the way real design is done by real designers, selecting the optimum materials for a successful product."
