In the last 100 years, knowledge of the basic science of materials has enabled scientists to engineer materials that meet ever more demanding specifications. The cutting edge nanotechnology promises to create new materials that will revolutionize many fie
example a material property called Yield Strength is the level of stress (load divided by cross sectional area) at which point the material starts to yield (permanently deform). So this property measures a material's response to a mechanical stimulus. (Us
One can qualitatively say that metals are strong and shiny. Or that polymers are ductile. But how strong? How shiny? How much deformation will a polymer experience for a certain load? These kinds of questions relate to the quantification of material prope
Material properties are the inherent characteristics of a material. These can be described qualitatively and quantitatively.

The Structure of Materials
The structure of materials can be discussed on different levels (scales) ranging from the human scale to the atomic scale:

A materials structure determines its properties which in turn determine the applications for which it can be used. However, with knowledge of the structure and some creativity, the engineer can formulate a process that will change the structure and enhanc
How does it all relate? The fundamental science of materials looks at their structure and properties. Materials engineering is the processing and selection of materials. These concepts relate to each as follows. Processing Structure Properties Application
The word science refers to the fundamental nature of the physical world. The science of materials refers to their structure and their properties.
Ask ten engineers what the definition of the word engineering is and you will get several
Material must meet design
specifications. (strength, durability, etc.) 2. Cost effective. (Both the material
itself and its processing.) 3. Environmental impact. (Must take
into account cradle to grave impact.) 4. Deterioration potential.
An alternate classification of materials uses categories based on their properties: 1. 2. 3. 4. 5. Structural materials Electronic materials Magnetic materials Semiconducting materials Optical materials
