Material Properties
Material properties are the inherent characteristics of a material. These can be described qualitatively and quantitatively.
One can qualitatively say that metals are strong and shiny. Or that polymers are ductile.
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
Science
The word science refers to the fundamental nature of the physical world. The science of materials refers to their structure and their properties.
Engineering
Ask ten engineers what the definition of the word engineering is and you will get several
In the field of materials, engineering refers to the processing techniques for materials and to the selection of an appropriate material for a specific application.
1.
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.
Criteria for selection of materials
Engineers must take into account various considerations when selecting materials for an application.
Some of the more obvious criteria:
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
Classification of Materials
One way to classify materials is in these six categories: 1. 2. 3. 4. 5. 6. Metals/Alloys Ceramics Glasses Polymers Composites Semiconductors
2. electrical properties measure the response to an electric field (e.g. conductivity) 3. thermal properties measure the response to heat (e.g. melting temperature) 4. magnetic properties measure the response to a magnetic field (e.g. permeability) 5. opt
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
