Text 2 the properties of the engineering materials (Part I)

In our daily lives we are constantly faced with the importance of finding suitable engineering materials. A complete knowledge of the properties of engineering materials would not only be required by engineers to prevent failure of structures and machines, but such knowledge would be necessary in order that these materials should be made use of most economically.

In recent years, the fact that some materials are available in sufficient quantities and the more effective use of new substitute mаterials required that a more thorough consideration of material properties be made. The science of engineering materials has led to the development of many alloys having much greater resistance to various loading conditions.

For many products made of non-metallic materials such as, for example, the tremendous amount of things manufactured using plastics, a consideration of engineering properties might be very important. It is often required that we should get information on the properties of materials subjected to most severe conditions of temperature, corrosion, etc. These conditions should be taken into account in the design of such constructions as gas and steam turbines for ships, rockets, jet engines, various equipment to atomic power stations. The development of materials required for the construction of many machines, structures and products used in our modern civilization is provided by a lot of engineers and scientists. In selecting the most suitable material and in the determination of the sizes of the required members, the designer might utilize the services of a materials engineer.
