The property of a material necessary for forgings, in stamping im

SOLUTION

Explanation:

Forging:

Forging may be defined as a metalworking process by which metals and alloys are plastically deformed to the desired shape by the application of a compressive force.

Different mechanical properties are:

• Plasticity: It is the property of a material by virtue of which a material deforms permanently.
  • This property of the material is necessary for forging in stamping images on coins and in ornament work.
• Elasticity: It is the property of a material by virtue of which it is able to regain its shape when the load is removed from it.
• Ductility: It is the property of a material by virtue of which it can be drawn into wires.
• Malleability: It is the property of a material by virtue of which it is able to flatten into thin sheets without cracking by a compressive force.
• Strength: It is the property of a material by virtue of which it is able to resist any deformation under loading.
• Hardness: It is resistance to penetration, scratching, abrasion or cutting.
• Toughness: It is the ability of a material to withstand both plastic and elastic deformation.
  • It is the amount of energy a material can absorb before an actual fracture.
• Brittleness: A material is brittle if when subjected to stress, it breaks without significant plastic deformation.
• Fatigue: The ability of a material to fracture by means of progressive fracture under repeated cyclic stresses of an intensity considerably below the normal strength.
• Creep: It is the permanent elongation of a component under a static load maintained for a period of time.
• Impact strength: It is the ability of a material to withstand a suddenly applied load.
