""Callister and Rethwisch?s Fundamentals of Materials Science and Engineering, 4th Edition continues to take the integrated approach to the organization of topics. That is, one specific structure, characteristic, or property type at a time is discussed for all three basic material types -- metals, ceramics, and polymeric materials. This order of presentation allows for the early introduction of non-metals and supports the engineer?s role in choosing materials based upon their characteristics. Also discussed are new, cutting-edge materials. Using clear, concise terminology that is familiar to students, Fundamentals presents material at an appropriate level for both student comprehension and instructors who may not have a materials background"-- Provided by publisher."

Ashby, Mike
"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."

"This book is both a course book and a monograph. The first chapter briefly introduces the history, background and technology of EPM. In the second chapter, the concept of transport phenomena is concisely introduced and in the third chapter the essential part of magnetohydrodynamics is transcribed and readers are shown that the concept of transport phenomena does not only apply to heat, mass and momentum, but also magnetic field. The fourth chapter describes electromagnetic processing of electrically conductive materials such as electromagnetic levitation, mixing, brake, and etc., which are caused by the Lorentz force. The fifth chapter treats magnetic processing of organic and non-organic materials such as magnetic levitation, crystal orientation, structural alignment and etc., which are induced by the magnetization force. This part is a new academic field named magneto-science, which focuses on the development of super-conducting magnets."

"Limbah minyak bumi (oily Sludge) merupakan bitumen industri yang berasal dari Lumpur (sludge) pengilangan yang dapat digunakan sebagai bahan baku cat berbitumen yang diharapakan tahan terhadap lingkungan yang mengandung asam, basa, panas, dan air. Untuk mengetahui manfaat sludge tersebut pada aplikasi proses pelapisan material (coating) maka dilakuakan penelitian pada skala laboratorium.
Penelitian ini menyangkut pengujian karakteristik bahan cat pelapis pada berbagai komposisi yang antara lain menggunakan bahan-bahan berupa resin, talk, lilin, aspal dan pelarut toluena. Pengujian yang dilakukan antara lain: ketahanan korosi berupa uji kabut garam, curing 150° C, uji ekspos atmosferik serta uji daya lekat dengan paint adhesion tester. Kemampuan lapis-ulang (recoatabilily) dari bahan cat tersebut diharapkan dapat diaplikasikan dengan baik. Di samping itu pula ketahanan panasnya dapat ditinbgkatkan secara signifikan.
Hasil penelitian menunjukan bahwa peningkatan kadar sludge akan meningkatkan ketahanan pelepuhan rata-rata 15 % per 20 gram kenaikan kadar sludge dari 100 gram sampai dengan 120 gr. Namun peningkatan kadar sludge dari 120 gram sampai dengan 140 gram cenderung menurunkan daya rekat sekitar 30% per 20 gram kenaikan kadar sludge. Peningkatan sludge/resin akan menurunkan nilai ketahanan korosi dan pelepuhan. Rasio komposisi minimum sludge : resin yaitu 140:40 menunjukan nilai ketahanan korosi dan nilai ketahanan pelepuhan masing-masing sebesar 8(10 adalah nilai terbaik), sedangkan rasio komposisi maksimum sludge resin yaitu 100: 80 menunjukan nilai ketahanan pelepuhan sebesar 9 (10 adalah nilai terbaik). Ketahanan panas dapat ditingkatkan secara signifikan yaitu sekitar 35% per 20 gram peningkatan resin."

"Komposit merupakan material yang sedang dikembangkan, yang terdiri dari dua jenis material atau lebih untuk meningkatkan sifat mekanis. Salah satu aplikasinya yaitu pada tabung roket, yang menggunakan komposit berbahan dasar logam Metal Matrix Composite . Material yang digunakan yaitu Al 6061 dengan penambahan partikel nano SiC 0.15 Vf sebagai penguat, Mg 10 wt. sebagai agen pembasah, dan variabel TiB sebesar 0.02, 0.03, 0.04, 0.05, dan 0.06 wt. sebagai pemodifikasi butir agar lebih halus dan meningkatkan sifat mekanis. Hasil dari penelitian ini menunjukan dengan adanya penambahan partikel nano SiC dan TiB sebagai pemodifikasi ukuran butir, dapat meningkatkan sifat mekanis. Penambahan TiB yang paling baik yaitu pada pada penambahan 0.06 wt. dengan kandungan aktual pada komposit sebesar 0.0535 wt. , yang menghasilkan nilai kekuatan tarik sebesar 204.9 MPa, nilai kekerasan 53.58 HRB, dan laju keausan sebesar 0.0012 mm3/m. Peningkatan sifat mekanis disebabkan karena terdapat fasa Mg2Si sebagai penguat, lalu TiB2 sebagai agen nuklean yang memperhalus butir, dan fasa MgAl2O4 yang berada pada antarmuka partikel nano SiC dengan matriks sehingga memiliki pembasahan yang baik.
Composite is advance material that being developed, that contains of two materials or more to improve the mechanical properties. One of the application is rocket tube, that using metal matrix composite MMC . The base material is Al 6061 with addition of nanoparticles SiC 0.15 Vf as reinforcment, Mg 10 wt. as wetting agent, and variables of TiB 0.02, 0.03, 0.04, 0.05, and 0.06 wt. as grain refiner so it can improve the mechanical properties too. The result of this research, that with addition of nanoparticles SiC and TiB as grain refiner, it make the improvement of mechanical properties. The best addition of TiB is with the addition of 0.06 wt. TiB, which is the actual content in composite is 0.0535 wt. . The result shows that the Ultimate Tensile Strength reached 204.9 MPa, the hardness is 53.58 HRB, and the wear rate is 0.0012 mm3 m. The improvement of mechanical properties are because of there are Mg2Si phase as second phase that increase the strength of material, TiB2 as the nuclean to refine the grain, and MgAl2O4 phase that exist in the interface of nanoparticles SiC and the matrix, so it have good wettability between nanoparticles SiC and the matrix."
