Materials science has deeper roots in our culture than perhaps most of us realize. Transportation, housing, clothing, communication, recreation, food production-almost all segments of our daily lives are affected to some extent by materials. Historically, the development and development of society
It is closely tied to the ability of members to produce and operate materials to meet their needs. In fact, the early civilization is specified by the level of its material development ( ie, the Stone Age, the Bronze Age).
Early humans had only access to a very limited number of naturally occurring materials, such as stone, wood, clay and skin. Overtime they discovered techniques for producing materials that had superior properties than those of natural ones; these new materials included pottery and various metals. In addition, it was discovered that the properties of the material can change due to heat treatment and the addition of other substances. At this time, the use of materials was completely a selection process. That is, from a given, fairly limited set of materials, determine what is most suitable for the application due to its properties.
It was not until relatively recently that scientists began to understand the relationship between the structural elements of materials and their properties. This knowledge gained in the last 60 years or so gave them the power to greatly fashion the properties of the material.
Thus, tens of thousands of different materials with fairly specific properties have evolved, such as metal, plastic, glass and fiber, to meet the needs of modern complex societies.
Description
The Basics of Materials Science and Engineering is an alternative version of my text, Materials Science and Engineering: Introduction, fifth edition. Both contents are the same, but the order of presentation is different, and the foundation utilizes new technologies to enhance teaching and learning.
As for the order of presentation, there are two common approaches: what I call the “traditional” approach and what I call the most “integrated” approach. In the conventional approach, the structure/properties/properties of metals are presented first, followed by a similar discussion of ceramic materials and polymers.
Introduction, the 5th edition is structured in this way and is preferred by many materials science and engineering lecturers. In an integrated approach, a specific structure, characteristic, or characteristic of all 3material types is presented before moving on to another structure/characteristic/characteristic discussion. This is the order of presentation of the foundation.
