There are thousands of materials available for use in engineering applications. % Cements and concrete Cermets (metal-ceramic). 25, 27 Melting temperature of the metal Melting range Melting temperature of the alloy Casting shrinkage Casting shrinkage is the sum of o Liquid shrinkage: The volume of the liquid decreases during cooling. Iron and steels Polyethylene (PE) For brittle solids: ceramics, glasses and brittle polymers - it is much less than the compressive elastic limit. In casting, a material in liquid form is poured into a mold where it is allowed to solidify by cooling (metals) or by reaction (plastics). means that it is very difficult for atoms to slide past each forming ordered structures (so remain amorphous and A regular focus on technical and semi-technical vocabulary enables learners to become familiar with and practise using the specialist language they need for work. strong and stiff, giving metals high stiffness and strength, Poor fluidity is less concern when the metal is cast by plaster or investment casting processes (slower cooling!)

This effect is caused by dynamic recrystallisation during deformation of the material. It relates heat flow (the flow of heat energy per unit area per unit time) to the temperature gradient (which describes a temperature difference per unit distance), causing the heat flow. The most common manufacturing processes are: a. Units: SI: 10 6 V/m; cgs: V/cm; English: V/mil Dielectric Constant When a material (such as that used in a capacitor) is placed in an electric field, it becomes polarised and charges appear at its surfaces which tend to screen (separate) the interior from the external field. It is represented in the following equation; = m / V Cost (YTL/kg) Anisotropy Definition: The characteristic of exhibiting different values of a property in different directions.
