Purpose: In this lab‚ we will heat up a metal rod and measure how much it expands. We will calculate its Coefficient of Linear Expansion‚ α‚ and prove the formula for thermal expansion‚ ΔL = αLiΔT. Also‚ we heat up a known volume of methyl alcohol and calculate its Coefficient of Volume Expansion‚ β‚ and prove the formula for volume expansion of a liquid ΔV = βViΔT. Equipment: Hollow Metal Rods of different metals‚ Steam Generator‚ Stand‚ Burner‚ Flexible Hoses‚ Motion Amplifier‚ Micrometer

Extrusion is the process by which a block/billet of metal is reduced in cross section by forcing it to flow through a die orifice under high pressure. • In general‚ extrusion is used to produce cylindrical bars or hollow tubes or for the starting stock for drawn rod‚ cold extrusion or forged products. • Most metals are hot extruded due to large amount of forces required in extrusion. Complex shape can be extruded from the more readily extrudable metals such as aluminium. * The products obtained are also

STRENGTHENING OF METALS There are 4 major ways to strengthen metals‚ and all work because they make dislocation motion more difficult. They also reduce the ductility: 1) Cold work (Strain Hardening) 2) Reduce grain size (Strengthening by Grain Size Reduction) 3) Add other elements in solid solution (Solid Solution Strengthening) 4) Add second phase particles (Precipitation or Age Hardening) • These mechanisms may be combined. • For example‚ the world’s strongest structural material (with
