Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
[mass noun] A solid solution of carbon in a non-magnetic form of iron stable at high temperatures. It is a constituent of some forms of steel.
- ‘When the steel is heated well above the upper critical temperature large austenite crystals form.’
- ‘With some steels, the enriched austenite does not precipitate carbide, but remains as a film of retained austenite.’
- ‘At higher temperatures, the structure switches to austenite.’
- ‘Aluminum is widely used as a deoxidizer and was the first element used to control austenite grain growth during reheating.’
- ‘Titanium can reduce carbon in austenite by forming very stable carbides.’
- ‘This soft retained austenite can accommodate impact stresses better than the harder constituents.’
- ‘This high temperature treatment produces uniform austenite of rather large grain size.’
- ‘This implies that after hardening these steels practically always contain some residual austenite.’
- ‘This level of carbon also decreases the solubility of the microalloying constituents in austenite.’
- ‘Premature austenite decomposition has been found to be detrimental to mechanical properties.’
Early 20th century: from the name of Sir William Roberts-Austen (1843–1902), English metallurgist, + -ite.
