Definition of ductile in English:



  • 1(of a metal) able to be drawn out into a thin wire.

    • ‘The nonmetals are neither malleable nor ductile; if drawn out or hammered, they shatter.’
    • ‘These steels remain ductile at the lowest resting temperatures.’
    • ‘Zirconium and zirconium-tin alloys are ductile metals and can be prepared by conventional processes.’
    • ‘The process is readily adaptable to joining ductile metals.’
    • ‘However, the structural steel is more ductile and has a greater total elongation.’
    • ‘Copper is a fairly soft, reddish brown metal that is quite ductile.’
    • ‘Palladium is a relatively soft, silver-white metal that is both malleable and ductile.’
    • ‘Iridium is neither very ductile nor malleable at room temperature, although it becomes more ductile at higher temperatures.’
    • ‘The current trend is to the more rational approach of basing the static design of ductile metals on the yield strength.’
    • ‘Despite Cal's returned stare he remained defiant in his obvious scrutiny of Cal from behind the glossy sheen of spectacles framed in yet more ductile gold.’
    • ‘Zinc is a bluish white metal that is neither ductile nor malleable.’
    • ‘Lanthanum is a white metal that is both ductile and malleable.’
    • ‘Niobium is a ductile and soft metal at elevated temperatures.’
    • ‘Iron is a silvery white or grayish metal that is ductile and malleable.’
    • ‘Hafnium is a bright, silvery gray metal that is very ductile.’
    • ‘Lutetium is a silvery white metal that is quite soft and ductile.’
    • ‘Nickel is a silvery white metal and is both ductile and malleable.’
    • ‘The straight sections of the side members are made of high-strength steel, a very ductile grade of material, selected specifically for high energy absorption.’
    • ‘Extremely ductile, a gram of silver may be drawn out into a wire 180 meters long.’
    • ‘It is the most ductile and malleable of all metals.’
    1. 1.1 Able to be deformed without losing toughness; pliable, not brittle.
      • ‘These are predominantly ductile structures that were overprinted by more brittle structures at later stages.’
      • ‘We plan to do additional work to improve the quality of carbon nanotube dispersion and use more ductile binder resins.’
      • ‘It is important to note that potassium feldspar did not deform in a ductile fashion during post-peak-metamorphic deformation.’
      • ‘The sedimentary units in the hanging wall were deposited in fault-bounded basins while their footwalls progressively emerged through the ductile and brittle crust.’
      • ‘Internal thickening of units is common and can be very difficult to evaluate, particularly in the shaly units that deform on the large scale in a ductile manner.’
      • ‘Thus this fault zone also appears to have a ductile history with a brittle overprint.’
      • ‘This dilated carapace is weak, slippery and ductile when wet, but brittle and elastic when dry.’
      • ‘We use a special epoxy developed by 3M which is more ductile (less brittle) which optimizes performance when subject to a vibrating load.’
      • ‘As is well known, a normally ductile material will fail in brittle mode at high enough strain rate and the transient pressure could rise well above that required for fracture if source build-up rate exceeded its discharge rate.’
      • ‘The ductile structures show a progressive evolution into semi-ductile and brittle deformation.’
      • ‘Some are ductile and others brittle since the transition temperature is near room temperature.’
      • ‘Simply put, the micro-cracking of the more brittle cement matrix engages the more ductile fibers in resisting the load.’
      pliable, pliant, flexible, supple, plastic, tensile, tractile

Middle English (in the sense ‘malleable’): from Latin ductilis, from duct- ‘led’, from the verb ducere.
