ENGINEERING MATERIALS.

LABORATORY REPORT.

This report booklet is to be used for any practical laboratory/workshop assessment carried out as part of your coursework in Materials Engineering.

The report is available as hard copy for writing out by hand. It is also available in electronic form should the student prefer to word process the assignment.
All parts of this workbook MUST be completed by the student, including the Bibliography and Reference section.

Whilst it is important to carry out any experimental work methodically and as accurately as possible and present it in an acceptable manner, it is your DISCUSSION of the results obtained and your CONCLUSION that carries the greatest amount of marks.
This twelve page booklet should allow a practical laboratory session to be written up fully. However, supplementary pages are available from your tutor or via the college intranet facility (Blackboard) should extra pages be needed. These should be submitted with this booklet.

Finally, the completed report MUST be submitted within the deadline given by your tutor along with a student feedback sheet, in accordance with departmental policy.

    Metallurgy: The Bronze Age Metallurgy was first practiced in Asia Minor a little after 4000 B.C.E, afforded individuals greater control over nature by providing harder, more efficient tools and weapons. At first copper ore was taken from the surface, but metalsmiths mined and smelted various ores to produce bronze. The technology of bronze-casting spread from Mesopotamia throughout the ancient world. In India, advanced metalwork techniques were used to produce jewelry, musical instruments, horse…

    Powder metallurgy is the process of blending fine powdered materials, pressing them into a desired shape or form (compacting), and then heating the compressed material in a controlled atmosphere to bond the material (sintering). The powder metallurgy process generally consists of four basic steps: (1) powder manufacture, (2) powder blending,(3) compacting, (4) sintering. Compacting is generally performed at room temperature, and the elevated-temperature process of sintering is usually conducted at…

    Being a welder is a great occupation What is welding, and how does it work? Not many people know what welding is or how it works. According to Mary Bonk“welding is the process of heating and melting metal parts to join them together” (Bonk,3). A welding machine uses electricity to melt the electrode, fusing one piece of metal to another. The welding machine uses a ground that connects to the surface that allows the welder to create a flowing currant passing through the electrode and…

    TIG welding T ungsten inert gas (TIG) welding is a high quality low deposition rate welding process. It uses an arc struck between a nonconsumable tungsten electrode and the work to fuse the base material and thereby form a welded joint. The TIG welding process may be used on thin sheet material without the addition of a filler metal (autogenous TIG welding). Alternatively, when working on thicker sheet or when joining dissimilar materials, a separate wire filler metal is added…

    WELDING OF CAST IRON Cast iron is an extremely versatile material, used in thousands of industrial products. It is hard, wearresistant, and relatively inexpensive. Like steel, it is available in many different grades and compositions. While we usually think of cast iron as being brittle (having low ductility), this is not true of all cast irons, as we shall see shortly. Cast iron, like steel, is an iron-carbon alloy. In composition and structure, and in some of its properties, it is quite different…
