How the production of metal contributes to computer engineering designing?
The goal of materials science is to empower scientists and engineers to make informed decisions about the design, selection and use of materials for specific applications.
Four Fundamental Tenets Guide Materials Science
1. The principles governing the behavior of materials are grounded in science and are understandable.
2. The properties of a given material are determined by its structure. Processing can alter the structure in specific and predictable ways.
3. Properties of all materials change over time with use and exposure to environmental conditions.
4. When selecting a material for a specific application, sufficient and appropriate testing must be performed to ensure that the material will remain suitable for its intended application throughout the intended life of the product.
A materials scientist or engineer must be able to:
1. Understand the properties associated with various classes of materials.
2. Know why these properties exist and how they can be altered to make a material more suitable for a given application.
3. Be able to measure important properties of materials and how those properties will impact performance.
4. Evaluate the economic considerations that ultimately govern most material issues.
5. Consider the long-term effects of using a material on the environment.
The Fundamental Material - Atom
1. What are the atomic building blocks?
a) Nucleus - Protons (+) and Neutrons (0)
b) Electrons (-)
c) Atoms have a neutral charge (#protons =#electrons)
2. How are electrons distributed through an atom?
a) Electrons in organized shells in an electron cloud
b) # electrons/shell = 2N2
(N = the shell number)
3. What are valence electrons? Why are they important?
a) Valence electrons are in the outermost shell
b) Reactivity of atom depends upon valence electrons
4. Why are noble gases inert?
a) The noble gases have full shells of electrons.
