(A) Mechanical Testing on Various Materials.
Introduction
Different types of materials have different microstructures, which determine their properties. Engineers are interested in exploring the properties of these materials so that they can be better used in the correct representation.
There are three broad categories that are commonly used: metals, ceramic and polymers, as well as composite materials. This experiment studies the mechanical properties of the three materials and demonstrate the factors that affect the strength of each of the different materials.
Objective
- To understand different mechanical properties of materials.
- To observe how the three types if materials behave in their mechanical properties under the tensile test.
- To understand the major factors which determine those mechanical properties.
Introduction
Electron microscopes were developed due to the limitations of light microscopes which can only have a resolution of 2 micrometer.
The first electron microscope (SEM) appeared in 1942, it uses a beam of energetic electrons to examine objects of a fine scale. The sample examined is swept by the electrons beam across its surface. The signals generated by the interaction of the electron beam with its sample are collected by a variety of detectors. This provides up with the topography, morphology and the composition of the sample
Objective
1) Learn the basics of SEM theory and instruments.
2)
Learn the basics of Signal Detection theory and instrumentation for (SE)(BSE) and (EDX) detectors.
(C) Composite Materials Processing
Introduction
Composite Materials are a mixture of two or more materials. It has the desirable properties which cannot be attained by either material acting alone. Therefore these materials are used in transportation industries especially airplanes and also sports equipment.
Objectives
1) To understand what is composite materials and how to fabricate them.
2) To appreciate the applications of composite materials in daily life
3) To appreciate the mechanical properties of composites
