Findings from an initial independent metallurgical laboratory study found the failurewas caused by liquid metal embrittlement.
embrittlement in American English
(emˈbrɪtlmənt)
noun
the act or process of becoming brittle, as steel from exposure to certain environments or heat treatment or because of the presence of impurities
Word origin
[1915–20; embrittle + -ment]This word is first recorded in the period 1915–20. Other words that entered Englishat around the same time include: conditioning, feedback, markup, neorealism, takeout-ment is a suffix of nouns, often concrete, denoting an action or resulting state (abridgment; refreshment), a product (fragment), or means (ornament)
