  3. 3. www.metzlab.in 1. Introduction Ages Basic steps in metallurgy Materials: Substances of which something is composed or made. Every segment of our everyday lives is influenced to one degree or another by materials. Material Science: Investigating the relationship between the structure and properties of the materials Metallurgy: The science and technology of extracting metals from their natural sources and preparing them for practical use
  4. 4. www.metzlab.in 1. Introduction Ages Basic steps in metallurgy Age of Steel  Petroleum Age  Industrial Age  Age of Flight  Space Age -Sputnik  Nuclear Age  Computer Age  Composite Material Age  Nano Tech Age  Green Age ? Modern Metal Age consists of many overlapping Technical Ages after 1300 Basic ages of metals in the ancient world
  5. 5. www.metzlab.in 1. Introduction Ages Basic steps in metallurgy The development of metallurgy was a long, and sometimes devious process that involved five basic steps. 1. Identifying and discovering its usefulness 2. Locating metals in quantity 3. Mining the ores. 4. Smelting the metal. 5. Shaping the metal into something useful.
  6. 6. www.metzlab.in 2. Material science Structure Property Processing Performance Material science has four basic elements. 1. Structure 2. Property 3. Processing 4. Performance Property
  7. 7. www.metzlab.in 2. Material science Structure Property Processing Performance The structure of a material usually relates to the arrangement of its internal components. subatomic atomic microscopic macroscopic Electrons within individual atom and interaction with nuclei Organization of atoms or molecules related to one another Large groups of atoms, direct observation by microscope Structural elements may be viewed with naked eye
  8. 8. www.metzlab.in 2. Material science Structure Property Processing Performance Property is a material trait in terms of the kind and magnitude of response to a specific imposed stimulus. Mechanical (Strength, Hardness, Ductility, Stiffness) Electrical (Electrical conductivity, Dielectric constant) Thermal (Heat capacity, Thermal conductivity) Magnetic (Magnetic moment, Magnetic permeability) Optical (Refraction index, Reflectivity) Deteriorative (Corrosion)
  9. 9. www.metzlab.in 2. Material science Structure Property Processing Performance Processing: different ways for shaping materials into useful components or changing their properties.  Casting  Forming  Welding  Powder metallurgy
  10. 10. www.metzlab.in 2. Material science Structure Property Processing Performance Performance: a function of a material’s properties.

Advanced Materials Nano materials It enables to carefully arrange atoms to develop mechanical, electrical, magnetic, and other properties. “Bottom-up” sciences called nanotechnology. Nano = 10-9, nanotechnology < 100 nm equivalent 500 atom diameters Electronic materials Bio materials Nano materials Carbon based nanotubes Bucky Ball (C60)
  20. 20. www.metzlab.in 5.Metallurgy process Casting Forming Welding Powder metallurgy Casting Casting A manufacturing process that pours a liquid material into a hollow mould until the material cools into a solidified shape
  21. 21. www.metzlab.in 5.Metallurgy process Casting Forming Welding Powder metallurgy Forming Forming operations change the geometry of the starting material without cutting it. Rolling: Compressive deformation process in which the thickness of a plate is reduced by squeezing it through two rotating cylindrical rolls. Forging: The work piece is compressed between two opposing dies so that the die shapes are imparted to the work. Extrusion: The work material is forced to flow through a die opening taking its shape Drawing: The diameter of a wire or bar is reduced by pulling it through a die opening (bar drawing) or a series of die openings (wire drawing)
  22. 22. www.metzlab.in 5.Metallurgy process Casting Forming Welding Powder metallurgy Forging A metal is shaped by compressive forces Oldest metal working process – 4000BC Can be performed with a hammer and anvil
