Definition of embrittle in US English:



  • Make or become brittle.

    no object ‘the joints do not embrittle in extreme cold’
    • ‘Titanium can withstand much more oxygen or nitrogen before becoming embrittled; however, small amounts of hydrogen will cause embrittlement.’
    • ‘Recently the titanium industry has become aware that hydrogen is a major factor in embrittling titanium.’
    • ‘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.’
    • ‘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.’
    • ‘Sulfur is particularly aggressive in that it diffuses more rapidly and embrittles more severely than does oxygen.’
    • ‘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.’
    • ‘Hydrogen is the most effective embrittling agent for Va metals.’
    • ‘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.’
    • ‘Because of the high solubilities in niobium and tantalum, these embrittling contaminants normally do not present problems in fabrication.’
    • ‘Consequently, the material is embrittled by impurity segregation to interfacial boundaries.’
    • ‘This is because some of the alloying elements form oxides and other compounds at the grain boundaries, embrittling the material.’
    • ‘Annealing embrittles the steel by the formation of carbides at the grain boundaries.’
    • ‘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.’
    • ‘This allows for improvement in the strength without embrittling the plastic.’
    • ‘Nickel has a strengthening effect, similar to that of manganese, although more limited because it only acts to reduce the embrittling effect of iron.’
