Though the reader can consult the following books; the contents of the e-book course may often differ in the rigour and details from these and other books.Basic ReferencesMaterials Science and Engineering (5th Edition) V. Raghavan Prentice-Hall of India Pvt. Ltd., 2004.Callister's Materials Science and Engienering William D Callister (Adapted by R. Balasubramaniam) Wiley Inida (P) Ltd., 2007.The Science and Engineering of Materials Donald. R.

Introduction to diverse kinds of engineering materialsOverview of what determines the properties of materials and how we engineer themStructure of materials and various lengthscales: crystal structure, electromagnetic structure, defect structure, microstructureStability and metastability of materials: the thermodynamics and kineticsThe tools used in materials science: x-ray diffraction, phase diagrams, TTT diagramsProperties of materials: elasticity, plasticity, fracture, fatigue, creep, conduction, magnetismWhat will you learn?This ebook hopefully will prove an invaluable guide to a learner of materials science & engineering(Credits, Syllabus, Marks are just incidental!)A teachers job is to uncover and not cover the syllabus- Richard M FelderClick here to take a diagnostic test to see if you are ready for this course!

The contents have been developed such that most of the material is in the form of figures, flow charts, video graphics and less is in the form of text. Hence, instead of saying happy reading we wish you happy viewing!Guidelines to ReadersInstruction for viewingUsing Powerpoint files (.ppt). Click on the relevant hyperlink on the Navigator page. In the PowerPoint presentations Right Click on the Menu bar to launch the web toolbar (you can use this to navigate back and forth)Using .pdf (Portable Document Format) files. Adobe Acrobat Reader- freeware (http://get.adobe.com/uk/reader/) will be required for this purpose.Using Open Office. Powerpoint (.ppt) and Open Office Presentation (.odp) files can be opened with Open Office (http://download.openoffice.org/). VIEWING POWERPOINT FILESStart with the PowerPoint files by double clicking on any file. To start PowerPoint (PPT) presentation from the first slide press F5To start PowerPoint (PPT) presentation from the current slide press Shift + F5To scroll down slides use Page Down or Text hyperlinks are underlined in blue colour OTHER TIPS IN VIEWINGText boxes and figures may also be hyperlinked (curser has to be placed on the item to see that it is hyperlinked- arrow will change into a hand())Some of the hyperlinks may have screen tips place curser on the hyperlink to see tipIf you want to open a hyperlink as a separate presentation Click on the hyperlinkIf you want to open a hyperlink within the current window in the current presentation press Control + Click on the hyperlink (this will work if you have launched the PPT file directly by double clicking)From a 'hyperlinked presentation' to come back to the main presentation press Esc

Note on accompanying videosAt various places in the chapters there are hyperlinks to videos (.mpg) files to view these you will need an appropriate viewer (e.g. windows media player). (.gif graphics will directly play inside .ppt)A listing of these videos is given in the video_library.pptThough the chapters are complete in themselves with figures, these videos give classroom style explanation of concepts using models.A note on the platform chosen for presentationWindows (XP) based applications have been used to develop the course material. These include: Word, Excel and Powerpoint (2003 versions)Users of Linux and other platforms may use the pdf version of the Word and Powerpoint files. Additionally, students not having access to Microsoft Office may use the OpenOffice freeware to open the MS office files: http://www.openoffice.org/ (download and install: http://download.openoffice.org/) (there might be some losses in conversion- which is usually not major if Office 2003 is used along with Open Office 3.1)Since concepts are presented in presentation mode,READ EVERY LINE AND EVERY WORD

The following hyperlinks are to file-wise substructure. Content-wise substructure will appear in respective chapters.1.

CHAPTER 12: Magnetic Materials

The course contents are extensive in some places and instructors may want to reduce the content in some topics.Instructors may download the appropriate files and delete the portion not needed. This will help tailor the contents for any specific syllabus or need.Any feedback or comments on improvement from instructors and students alike would be highly appreciated (anandh@iitk.ac.in).Guidelines to Teachers & Instructors
