What's the difference between ductility and fracture?

Ductility


Definition:

  • (n.) The property of a metal which allows it to be drawn into wires or filaments.
  • (n.) Tractableness; pliableness.

Example Sentences:

  • (17) The ductility and malleability of pure silver allow for ease of adaptation or alteration as a chairside or operating room procedure.
  • (18) (3) The simulated ceramic firing cycle created a small amount of ductility in SMG-2, but the lowering of the yield stress in Ceramco-0 renders the welds dangerously weak even with improved ductility.
  • (19) The fracture of the titanium specimens was ductile, with dimples occurring at the fracture surfaces.
  • (20) The superior ductility of needles made by one manufacturer was related to the specific alloy, stainless steel ASTM 45500, used in their production.

Fracture


Definition:

  • (n.) The act of breaking or snapping asunder; rupture; breach.
  • (n.) The breaking of a bone.
  • (n.) The texture of a freshly broken surface; as, a compact fracture; an even, hackly, or conchoidal fracture.
  • (v. t.) To cause a fracture or fractures in; to break; to burst asunder; to crack; to separate the continuous parts of; as, to fracture a bone; to fracture the skull.

Example Sentences:
