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.

So far I have principally treated materials just as 'stuff' that has a series of properties. You have seen that these properties vary from material to material but I have not really started to discuss why they do. I am not going to go into this in any real depth in this course but there is one important aspect of materials engineering that you have to know about before exploring materials processing much further.

Introduction to Engineering Materials

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. This paradigm is used to advance understanding in a variety of research areas, including nanotechnology , biomaterials , and metallurgy.

Sales Contacts. By: Dave Olsen. The mechanical and physical properties of materials are determined by their chemical composition and their internal structure, like grain size or crystal structure. Mechanical properties may be greatly affected by processing due to the rearrangement of the internal structure. Metalworking processes or heat treatment might play a role in affecting some physical properties like density and electrical conductivity, but those effects are usually insignificant. Mechanical and physical properties are a key determinant for which alloy is considered suitable for a given application when multiple alloys satisfy the service conditions. In almost every instance, the engineer designs the part to perform within a given range of properties.


The engineering materials are mainly classified as: 1. as-cast condition in a graphite free structure, i.e. total carbon content is present in its combined form.

Microstructural changes can be induced in almost all engineering materials to alter their mechanical properties. This is usually achieved through thermal treatments involving heating and cooling under controlled conditions.

Беккер толкнул двойную дверь и оказался в некотором подобии кабинета. Там было темно, но он разглядел дорогие восточные ковры и полированное красное дерево. На противоположной стене висело распятие в натуральную величину. Беккер остановился. Тупик. Стоя возле креста, он слушал, как приближаются шаги Халохота, смотрел на распятие и проклинал судьбу.

Я не мог позволить себе роскошь… - Директор знает, что вы послали в Испанию частное лицо. - Сьюзан, - сказал Стратмор, уже теряя терпение, - директор не имеет к этому никакого отношения. Он вообще не в курсе дела. Сьюзан смотрела на Стратмора, не веря своим ушам. У нее возникло ощущение, что она разговаривает с абсолютно незнакомым человеком. Коммандер послал ее жениха, преподавателя, с заданием от АНБ и даже не потрудился сообщить директору о самом серьезном кризисе в истории агентства.
