Metallic Materials And Processes I

  1. 1. Metallic Materials and Processes I Student: Jordan Hites Instructor: Dr. John Mativo
  2. 2. Course Description <ul><li>Major metallic industrial materials and their processes. The conversion of raw materials via extraction, refining, and processing into consumer products. An emphasis on safety metallurgy, nondestructive testing, destructive testing and material processing will be applied. </li></ul>
  3. 3. Course Objectives (1-3 of 6) <ul><li>Develop an awareness of how American Industry correlates to the use of metallic materials. </li></ul><ul><li>Describe the processes of how metallic materials flow from the raw state to a finished product. </li></ul><ul><li>Develop manipulative skills pertaining to material testing and processing. </li></ul>
  4. 4. Course Objectives (4-6 of 6) <ul><li>Develop an awareness of the importance of the design function, creativity, and crafts-persons-ship. </li></ul><ul><li>Develop proper safety habits and procedures related to testing and processing of materials. </li></ul><ul><li>Acquire basic knowledge of grain structure of materials. </li></ul>
  5. 5. Activities <ul><li>Metal box </li></ul><ul><li>Tool gage </li></ul><ul><li>Name plate </li></ul><ul><li>Chisel </li></ul>
  6. 6. Metal Box <ul><li>Gain knowledge on sheet metal behavior by cutting, bending, and folding. </li></ul><ul><li>Use fastening techniques to join sheet metal. </li></ul><ul><li>Develop layout process of sheet metal. </li></ul><ul><li>Optimize use of given material. </li></ul><ul><li>Use sheet metal hand tools. </li></ul>
  7. 7. Tool Gage <ul><li>Gain knowledge on behavior of flat bar shaping. </li></ul><ul><li>Use hacksaw to cut and square metal, files to remove burrs, and drill press to make holes. </li></ul><ul><li>Develop a layout and use it to shape metal. </li></ul><ul><li>Use simple trigonometry to calculate angle to be cut. </li></ul>
  8. 8. Chisel <ul><li>Illustrate and experience effects of heat treatment of ferrous metal. </li></ul><ul><li>Learn the correct operation and use of the furnace, anvil, tongs, and hammer. </li></ul><ul><li>Safety with hot metal. </li></ul><ul><li>Making better tools through forging. </li></ul><ul><li>Cooling rate effects on hot metal. </li></ul><ul><li>Use of sandblaster and files. </li></ul>
  9. 9. Name Plate <ul><li>Illustrate and experience casting operations. </li></ul><ul><li>Use of casting equipment and materials. </li></ul><ul><li>Make a pattern for the mould cavity. </li></ul><ul><li>Use molten metal to make a cast. </li></ul>
  10. 10. Material Properties <ul><li>As strength and hardness increase, ductility decreases and material becomes brittle </li></ul><ul><ul><li>Ductile materials resist shock better and absorb more energy before failure than brittle materials. </li></ul></ul><ul><ul><li>Brittle materials are usually stronger than ductile materials. </li></ul></ul><ul><ul><li>Stress = Force / Area </li></ul></ul><ul><ul><li>Strain = Final length / Original length </li></ul></ul>
  11. 11. Conclusion <ul><li>Strengths </li></ul><ul><ul><li>Hands-on experience </li></ul></ul><ul><ul><li>Instructor always willing to help </li></ul></ul><ul><ul><li>Light-hearted attitude and environment </li></ul></ul><ul><li>Weaknesses </li></ul><ul><ul><li>None </li></ul></ul>
