What's the difference between ductile and malleable?

Ductile


Definition:

  • (a.) Easily led; tractable; complying; yielding to motives, persuasion, or instruction; as, a ductile people.
  • (a.) Capable of being elongated or drawn out, as into wire or threads.

Example Sentences:

  • (9) Analysis of the stress-strain curves revealed a transition in the type of deformation at this point from pseudo-ductile to brittle.
  • (10) This composition is consistent with the hypothesis that the cement line provides a relatively ductile interface with surrounding bone matrix, and that it provides the point specific stiffness differences, poor 'fiber'-matrix bonding and energy transfer qualities required to promote crack initiation but slow crack growth in compact bone.
  • (11) The parameters used to assess performance were sharpness, resistance to bending, and ductility.
  • (12) maize starch and polymeric materials, there was an increase in the yield pressure with punch velocity attributable to a change either from ductile to brittle behaviour or a reduction in the amount of plastic deformation due to the time dependent nature of plastic flow.
  • (13) The purpose of this research was to evaluate the torsional strength and ductility of CP titanium in the as received condition, heat treated below the alpha----beta transition temperature, and glass bead blasted.

  • (15) The proximal end is ductile and the distal end rigid.
  • (16) A more ductile PLLA exhibiting a lower rate of degradation was prepared by extraction of low molecular weight compounds with ethyl acetate.
  • (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.

Malleable


Definition:

  • (a.) Capable of being extended or shaped by beating with a hammer, or by the pressure of rollers; -- applied to metals.

Example Sentences:

  • (1) The wire consists of a flexible, 49-strand, stainless steel cable connected on one end to a short, malleable, blunt leader with the opposite end connected to a small islet.
  • (2) Larson said misconceptions about Tubman had flourished in part because she was a “malleable icon”.
  • (3) The use of a malleable curved disposable suction cautery for the control of any persistent bleeding at the conclusion of adenoidectomy in over 1000 cases has prevented any primary postoperative hemorrhages from the nasopharynx, and obviated the need for post-nasal packing.
  • (4) These results indicate that the Nh genome is extremely malleable and large portions may be non-essential for growth in culture.
  • (5) Collectively, these findings indicate that the malleability of learned behavior is not simply a function of initial associative strength but is dependent on path during initial acquisition.
  • (6) In an attempt to minimize operating time and donor-site morbidity--as well as obtain a more malleable graft--we used liposuction to obtain our fat grafts for sinus obliteration.
  • (7) British law on photographing people in public places is still quite malleable.
  • (8) These changes in laminar distribution resemble the laminar specific decay of neuronal malleability and parallel the developmental redistribution of 1,4-Dihydropyridine-sensitive Ca channels.
  • (9) The plates show considerable advantages over existing small plate systems in their size, malleability and consequent ease of handling.
  • (10) These modifications include decreased width and thickness of the metal skeleton for easier application and increased malleability, respectively.
  • (11) These deformities can usually be corrected by appropriate splinting in the neonatal period, a time when estrogen activity is increased and the ear is very malleable.
  • (12) I look forward to what the least biblical of biblical films will do with this most malleable of texts.
  • (13) The goal of this study was to determine whether the use-dependent malleability of visual cortex functions which is particularly pronounced in 4-week-old kittens correlates with enhanced susceptibility to kindling.
  • (14) In order to verify these effects, the authors devised a multi-electrode, malleable plaque (63 electrode sites) that could be secured at the AV junction during venous occlusion in the open-chest, anesthetized dog.
  • (15) The pelvic-reconstruction plate is malleable and is more easily contoured in the operating room than a dynamic-compression plate.
  • (16) The facts do not support this assertion, and I will show, using examples from among the arthropods, that appropriate experiments often reveal competition, feedback, and prolonged periods of malleability much as they do for the vertebrates.
  • (17) Furthermore, they suggest as a possible reason for the decline of malleability towards the end of the critical period the reduction of NMDA receptors.
  • (18) The government’s desire for a more malleable Senate – one of its key reasons for calling a double dissolution – has backfired badly, with a similarly-sized, and likely equally recalcitrant, crossbench set to take seats on the red benches.
