“
So good, in fact, that toughness, ductility, and fatigue resistance - all intimately related properties - of the DH3 alloy improved to the point that the bulk metallic glass was not only stronger than many structural metal alloys but had a fatigue limit more than 30 percent higher than ultra-high-strength steel and aluminum-lithium alloys.

  1. That property of solid bodies, particularly metals, which renders them capable of being extended by drawing, with correlative diminution of their thickness or diameter, without any actual fracture or separation of parts. On this property the wire drawing of metals depends. It is greatest in gold and least in lead. Dr. Wollaston succeeded in obtaining a wire of platinum only of an inch in diameter. The order of ductility is—Gold, Silver, Platinum, Iron, Copper, Palladium, Aluminium, Zinc, Tin, Lead. A. Daniell, Prin. of Physics, p. 232.
  2. Flexibility; adjustability; ready compliance. It is to this ductility of the laws that an Englishman owes the freedom he enjoys. Goldsmith, Citizen of the World, i. In none of Dryden's works can be found passages more pathetic and magnificent, greater ductility and energy of language, or a more pleasing and various music. Macaulay, Hist. Eng., vii.

Examples (50)

  • An industrial process called "Kolsterising" (developed by the firm Bodycote) is able to increase the surface hardness of stainless steel to twice that of Super Bainite while maintaining its ductility - the extent to which a material can be deformed without fracturing. —  BBC News | News Front Page | World Edition
  • The more important purposes for which steel is annealed are as follows: to remove stresses; to induce softness; to alter ductility, toughness, electric, magnetic, or other physical and mechanical properties; to change the crystalline structure; to remove gases; and to prduce a definite microstructure. —  MyLinkVault Newest Links
  • The object of tempering a steel that has been hardened by quenching is to release stresses set up, to restore some of its ductility, and to develop toughness through the regulation or readjustment of the embrittled structural constituents of the metal. —  MyLinkVault Newest Links
  • * The difference between malleability and ductility is that malleability is the ability to deform easily upon the application of a compressive force, and ductility is doing the same with tensile force. —  Yahoo! Answers: Latest Questions
  • Commonly, the term "ductility" is used to refer to both concepts, as they are very similar. —  Yahoo! Answers: Latest Questions
