单词 embrittle
释义

Definition of embrittle in English:

embrittle

verbɛmˈbrɪt(ə)lɪmˈbrɪt(ə)ləmˈbridl
  • Make or become brittle.

    (使)变脆

    with object it was found that cotton and rayon could be made crease resisting, although the products were greatly embrittled
    no object the joints do not embrittle in extreme cold
    Example sentencesExamples
    • Because of the high solubilities in niobium and tantalum, these embrittling contaminants normally do not present problems in fabrication.
    • Recently the titanium industry has become aware that hydrogen is a major factor in embrittling titanium.
    • Titanium can withstand much more oxygen or nitrogen before becoming embrittled; however, small amounts of hydrogen will cause embrittlement.
    • This is because some of the alloying elements form oxides and other compounds at the grain boundaries, embrittling the material.
    • This allows for improvement in the strength without embrittling the plastic.
    • The organic materials in grounds, gilding, paint films, and varnishes become embrittled with age and can no longer flex to accommodate movement in the support.
    • These effects combine to make phosphorus an extremely effective embrittling agent, even when fracture occurs transgranularly.
    • Consequently, the material is embrittled by impurity segregation to interfacial boundaries.
    • Annealing embrittles the steel by the formation of carbides at the grain boundaries.
    • The high temperature treatment effaces the strains, coalesces the sulphide films in the ferrite which embrittle the steel and produces homogenity by rapid diffusion.
    • Of the many methods for gas brazing other metals, only the oxyacetylene gas has been found effective to date with titanium in that the gas employed does not embrittle the material.
    • Nickel has a strengthening effect, similar to that of manganese, although more limited because it only acts to reduce the embrittling effect of iron.
    • Its excellent toughness is due to a fine-grained structure of tough nickel-ferrite devoid of embrittling carbide networks, which are taken into solution during tempering at 570°C to form stable austenite islands.
    • The major powder preparation for other metals is accomplished by the relatively simple hydriding process in which the metal is embrittled with hydrogen and therefore more easily pulverized.
    • Hydrogen is the most effective embrittling agent for Va metals.
    • This alloy is, however, not satisfactory for use at elevated temperatures because it is age hardenable, and becomes embrittled.
    • It is extremely important that the salts be free of all traces of sulfur, so that the work does not become embrittled.
    • Sulfur is particularly aggressive in that it diffuses more rapidly and embrittles more severely than does oxygen.

Derivatives

  • embrittlement

  • noun
    • A serious embrittlement sometimes arises after prolonged treatment owing to the formation of cementitic films at the ferrite boundaries.
      Example sentencesExamples
      • It has also been shown that the development of temper embrittlement is directly linked with the rise of impurity concentration near the prior austenite boundaries.
      • Nickel and nickel alloys are susceptible to embrittlement by lead, sulfur, phosphorus, and other low-melting-point elements.
      • These steels do have some limitations, particularly those with higher chromium contents, where there can be a marked tendency to embrittlement.
      • Nickel-base alloys are frequently used because of their improved resistance to environmental embrittlement over steels and stainless steels.

Rhymes

acquittal, belittle, brittle, committal, it'll, kittle, little, remittal, skittle, spittle, tittle, victual, whittle
