The ability of materials to break into pieces among the application of tensile force. ]]> 2018-04-25 13:28:35 UTC https://padlet.com/enoliver/1em674b6glhh/wish/255218159 Examples enoliver https://padlet.com/enoliver/1em674b6glhh/wish/255218491 Gold and Silver are ductile materials while glass and ceramic are more brittle materials.]]> 2018-04-25 13:29:07 UTC https://padlet.com/enoliver/1em674b6glhh/wish/255218491 Tensile Strength enoliver https://padlet.com/enoliver/1em674b6glhh/wish/255218951 The ability of a material to stretch without breaking or snapping.]]> 2018-04-25 13:29:58 UTC https://padlet.com/enoliver/1em674b6glhh/wish/255218951 Malleability enoliver https://padlet.com/enoliver/1em674b6glhh/wish/255219472 The ability of a material to be reshaped in all directions without breaking.]]> 2018-04-25 13:30:54 UTC https://padlet.com/enoliver/1em674b6glhh/wish/255219472 Plastic enoliver https://padlet.com/enoliver/1em674b6glhh/wish/255220026
  • Plastic is a malleable material meaning it can be molded into different shapes multiple times this is why plastic is so common. 
  • Plastic is very easy to work and shape.

  • Stainless steel has a high ductility meaning it can be stretched into wire easily. 
  • Stainless steel is very popular because it can be molded into different flat shapes and it is resistant to corrosion so it won't rust.

  • Cast Iron is ductile so it can be drawn into wire easily. It is also a very tough material meaning it  can resist great force without breaking. 
  • It is also an elastic material so it can return to its original shape after being deformed.

  • Ceramics have high strength and high fracture resistants but they are still very brittle materials. This means they cannot stretch or be reformed they can only crack. 
  • They are also very hard  materials. An example would be glass.

  • Cold working increases ultimate tensile strength, yield point hardness and fatigue strength but decreases resistance to corrosion.
  • Cold working decreases mechanical properties of metal like elongation, reduction of area and impact values.

  • It increases mechanical properties.
  • In hot working, ultimate tensile strength, yield point, corrosion resistance are unaffected.

For example hot working makes it easier to form and reform a material such as steel and can make it easier to draw steal into a wire. ]]> 2018-04-25 14:22:02 UTC https://padlet.com/enoliver/1em674b6glhh/wish/255248370 enoliver https://padlet.com/enoliver/1em674b6glhh/wish/256859330 2018-05-01 14:09:37 UTC https://padlet.com/enoliver/1em674b6glhh/wish/256859330 enoliver https://padlet.com/enoliver/1em674b6glhh/wish/256859698 2018-05-01 14:10:14 UTC https://padlet.com/enoliver/1em674b6glhh/wish/256859698 enoliver https://padlet.com/enoliver/1em674b6glhh/wish/256859925 2018-05-01 14:10:40 UTC https://padlet.com/enoliver/1em674b6glhh/wish/256859925 enoliver https://padlet.com/enoliver/1em674b6glhh/wish/256860723 2018-05-01 14:12:14 UTC https://padlet.com/enoliver/1em674b6glhh/wish/256860723 enoliver https://padlet.com/enoliver/1em674b6glhh/wish/256861061 2018-05-01 14:12:51 UTC https://padlet.com/enoliver/1em674b6glhh/wish/256861061 enoliver https://padlet.com/enoliver/1em674b6glhh/wish/256862408 2018-05-01 14:15:31 UTC https://padlet.com/enoliver/1em674b6glhh/wish/256862408 enoliver https://padlet.com/enoliver/1em674b6glhh/wish/256862964 2018-05-01 14:16:31 UTC https://padlet.com/enoliver/1em674b6glhh/wish/256862964
