The interdisciplinary field of materials science , also commonly termed materials science and engineering , covers the design and discovery of new materials, particularly solids. The intellectual origins of materials science stem from the Enlightenment , when researchers began to use analytical thinking from chemistry , physics , and engineering to understand ancient, phenomenological observations in metallurgy and mineralogy. As such, the field was long considered by academic institutions as a sub-field of these related fields. Beginning in the s, materials science began to be more widely recognized as a specific and distinct field of science and engineering, and major technical universities around the world created dedicated schools for its study. Materials scientists emphasize understanding, how the history of a material processing influences its structure, and thus the material's properties and performance. The understanding of processing-structure-properties relationships is called the materials paradigm.

Check out our materials database with over common engineering materials! Metals are the most commonly used class of engineering material. The combination usually occurs through a process of melting, mixing, and cooling. The goal of alloying is to improve the properties of the base material in some desirable way. Metal alloy compositions are described in terms of the percentages of the various elements in the alloy, where the percentages are measured by weight. Ferrous alloys have iron as the base element. These alloys and include steels and cast irons.

Engineering Materials

By Duane Douglas Johnson. View Courses. This course introduces you to the materials science and engineering of metals, ceramics, polymers, and electronic materials. Topics include: bonding, crystallography, imperfections, phase diagrams, properties and processing of materials. Case studies are used when appropriate to exemplify the lecture topics. Related courses are mostly focussed on Mechanical Behavior.

Стратмор замолчал, словно боясь сказать что-то, о чем ему придется пожалеть. Наконец он поднял голову: - ТРАНСТЕКСТ наткнулся на нечто непостижимое.  - Он опять замолчал. Сьюзан ждала продолжения, но его не последовало. - Больше трех часов. Стратмор кивнул.

Он, как обычно, записал имена жертв. Контакты на кончиках пальцев замкнулись, и на линзах очков, подобно бестелесным духам, замелькали буквы. ОБЪЕКТ: РОСИО ЕВА ГРАНАДА - ЛИКВИДИРОВАНА ОБЪЕКТ: ГАНС ХУБЕР - ЛИКВИДИРОВАН Тремя этажами ниже Дэвид Беккер заплатил по счету и со стаканом в руке направился через холл на открытую террасу гостиницы. - Туда и обратно, - пробормотал. Все складывалось совсем не так, как он рассчитывал.

Вдалеке, метрах в пятистах, на фоне ночного неба возникли силуэты самолетных ангаров. Он подумал, успеет ли такси догнать его на таком расстоянии, и вспомнил, что Сьюзан решала такие задачки в две секунды.

 Сьюзан. Она была потрясена. Прямо перед ней во всю стену был Дэвид, его лицо с резкими чертами.
