Document Summary

Early civilization have been designated by the level of materials development. Every modern technology is material limited with respect to performance, reliability, cost. Basic compounds of material science and engineering (mse: processing, structure, properties, performance. Establishing the relationship among the processing, structures and properties of materials. Designing or engineering the structure of a material to produce desired properties on the basis of structure- property relationships. 4 levels of material structure: subatomic structure, atomic-level structure, microscopic structure, macroscopic structure. Property: a material trait according to the type and magnitude of response to a specific imposed stimulus including mechanical, thermal, electrical, magnetic, optical and chemical corrosive properties. 3 basics material types based on chemical composition and atomic structures: metals, ceramics, polymers. Advanced materials: materials used in high-technology (high tech) applications including semiconductors, biomaterials, smart materials, and nanomaterials.
