Material science, which is also known as material engineering, is considered an interdisciplinary field and it mainly applies the properties of matters on the earth to a variety of areas concerning science and engineering. In the more advanced stage, the discipline will reach a new scientific field to explore the connection between the structure of materials at the atomic or molecular level and their macroscopic attributes. Moreover, it also includes factors of applied physics and chemistry in which Nano science and nanotechnology have been put the most attention. With the further development, material science is more known as a particular field for science and engineering (Newey, etal, 1990)It should be noted that most of the difficult scientific issues in the world at the current stage, are caused by the limitation and restriction of materials which are available. Hence, once breakthroughs are made in this field it will have a far-reaching impact on the future development of technology. It is the purpose of this paper to explore the disciplinary literacy of material science, the method of building knowledge in this specific field so as to inform learners in the process of learning.
To begin with, it should be known that the chosen material of a certain era can be a turning point, such as the stone age, bronze age, the iron age as well as the steel age etc. Initially, the material science is derived from the ceramics manufacturing as well as its putative derivative metallurgy hence material science can be seen as one of the oldest types of engineering and applied science in the world. It is based on metallurgy that the modern material science is formed, and metallurgy is further evolved from mining, ceramics and the adoption ...

Some ceramics are used in orthopaedic applications such as bone repair, bone augmentation and joint replacement but their use in this field is not as extensive or widespread as metals and polymers because ceramics have poor fracture toughness. This severely limits the use of ceramics in load bearing applications (Davis, 2003).
Ultra high temperature ceramics (UHTCs) are materials rarely found in nature, characterized by high melting points, hardness, thermal conductivities (if compared to other ceramics), good wear resistance and mechanical strength.1,2,3 Besides, they are chemically and thermally stable under a variety of conditions due to their high negative free energy of formation.1,3

Pounding metal and fabricating metal in thin sheets and sections that humans need or want has a long history. The discovery of how to make and control fire made extracting metals form or more efficient instead of having to find almost pure nuggets of metal. In many civilizations copper was the metal they used but that was succeeded by bronze eventually it is made of copper and tin.

The objective of this lab is to illustrated the procedures required to perform tensile tests. Using data obtained from the test will enable the student to determine various material characteristics that affect the design process. Some findings/interpretations are the stress vs strain curve will help us show how the metal reacted to the forces applied, and the point of failure is very important as it is the ultimate strength.

Any person in these careers must be a proficient worker to have a successful career in these workplaces. Both careers involve a four year college. The education required for a materials scientist is a Bachelor’s Degree (“Chemists and Materials Scientists”). Also, the education required for aerospace engineers is a Bachelor’s Degree (“Aerospace Engineers”). However, some workers in the work force have degrees other than a Bachelor’s Degree. This means if a person is impelled to achieve greater in these careers, they can. Over three fourths of materials scientists have either a Bachelor’s, Master’s, or Doctoral Degree (“Materials Scientist”). While roughly 44% of aerospace engineers have a Master’s Degree, roughly 27% just have high school diplomas (“Aerospace Engineering and Operations Technicians”). Except on special occasions, both of these careers are very similar in the level of education

I have spent so much time learning about design through the paradigm of materials but now I want to connect mechanical aspects to the knowledge I have already gained. I am particularly interested in the research done by Dr. Drew Nelson, Dr. Sheri Sheppard and Dr. Friedrich Prinz whose work most closely fits my interests. I am interested in doing research in mechanical design as influenced by material usage. I am also looking forward to taking courses such as Imperfections in Crystalline Solids, The Magic of Materials and Manufacturing, and Nanomaterials Synthesis and Applications for Mechanical Engineers to explore topics I have already studied, but from a mechanical engineering perspective. Stanford’s combination of rigor and creativity appeal to me. I have always enjoyed a challenge and get great satisfaction from expanding my knowledge. Coming from a Materials Science and Engineering background where I have performed well, both in academics and leadership, I know I can be an asset to and learn from the world-class Mechanical Engineering program at

Mechanical Engineering has become one of the fastest growing career fields ever, due to our extremely technology based society. This field has been expanding to incorporate many specific parts of mechanical engineering. With this rapidly developing field in engineering, it would be nice to look back at the roots of how this career came to be. Also, this career paper will consist of the qualifications required to become a mechanical engineer and about how I qualify for the job.
Materials are used to manufacture useful objects. History proves that the material is the basis and the pilot of social progress and is a milestone in human progress. In the ancient time, the using of different materials determined the development of civilization, such as the Stone Age and the Bronze Age. In modern society, the development of iron and steel materials played the decisive role during the Industrial Revolution period. The development of semiconductor materials brought humanity into the Digital Age. Nowadays, people put materials, information, and energy as the three pillars of modern civilization. People pay more attentions on the study of material science and engineering because it can affect humans’ daily lives a lot. This major study in the discovery of new materials, the use of materials, the failure analysis, and the new materials technology have become high-tech technology that has significantly improved and changed people's lives. Also, people who study in this field will get higher quality lives.
But I did have an interest in materials. However, mechanical engineering is a very broad field. Mechanical engineering has an area of specialization referred to as “Materials and Manufacturing” [4] It doesn’t focus so heavily on material development and design so much as material selection and the methods of manufacturing parts using those materials. For example, “How do you mass produce carbon fiber parts?” would be a problem that a mechanical engineer of this specialization might set out to solve. At this point I had also had some exposure to electrical engineering, through a Snap Electronics kit and obtaining my Amateur Radio License. Mechanical engineers do take some electrical engineering classes. This gives mechanical engineers an understanding of electrical control systems and electric motors [5], both of which play important roles in machinery
