Experiment 1: Metallographic Observation and Analysis and Hardness Testing
Objective:
To determine the suitability of a material meaning its hardness distribution in grains, shape and size measuring a steel like material under the United Hardness Tester apparatus. In this experiment carbon steel AISI/SAE 1018 is used to determine the hardness using the “hardness testing electric system”.
Experiment 2: Metallographic Observation, Analysis and Hardness Testing
Objective:
The objective of this experiment is to be able to use different methods of heat treating in order to better understand how materials’ (AISI/SAE 1018 and 1045) hardness will be affected. The different heat treating methods used were normalization, quenching, and tempering.
Experiment 3: Precipitation Hardening of Aluminum Alloys
Objective:
to be able to use the aging and de-aging processes in order to observe the effects they have on the hardness of Al 6061.
Experiment 5: Tensile Test of Metals and Polymers
Objective:
To observe tensile properties of engineering which include the modulus of elasticity, yield stress, tensile stress, rapture stress, modulus of resilience, elongation, and % reduction in area. The materials being observed include brass, steel, and aluminum where their tensile tests are conducted on a tensile test machine and where their experimental tensile property values are compared to their standard tensile values.
Experiment 6: Torsion Test of Metals and Polymers
Objective:
To observe the modulus of elasticity of different engineering materials and to be able to develop a shear stress and shear strain diagram in the elastic range. In this experiment, the materials being used are a steel bar and an aluminum bar.
Experiment 7: Flexure Test of an Aluminum Cantilever Beam
Objective:
To observe flexural properties for engineering materials such as an aluminum beam or a concrete beam. The values analyzed will be the modulus of elasticity and Poisson’s ratio. The material being observed for the experiment is an aluminum beam.
