Definition of austenite in English:

austenite

noun ˈɒstɪnʌɪtˈɔːstɪnʌɪtˈôstəˌnīt

mass nounMetallurgy

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.
〔冶〕奥氏体
Example sentencesExamples
- This implies that after hardening these steels practically always contain some residual austenite.
- At higher temperatures, the structure switches to austenite.
- When the steel is heated well above the upper critical temperature large austenite crystals form.
- Aluminum is widely used as a deoxidizer and was the first element used to control austenite grain growth during reheating.
- This high temperature treatment produces uniform austenite of rather large grain size.
- Premature austenite decomposition has been found to be detrimental to mechanical properties.
- This soft retained austenite can accommodate impact stresses better than the harder constituents.
- This level of carbon also decreases the solubility of the microalloying constituents in austenite.
- With some steels, the enriched austenite does not precipitate carbide, but remains as a film of retained austenite.
- Titanium can reduce carbon in austenite by forming very stable carbides.

Derivatives

austenitic

adjective

Metallurgy

Stress corrosion cracking is very substantially reduced in high nickel austenitic alloys.
Example sentencesExamples
- One significant difference between the cast and wrought stainless steels is in the microstructure of cast austenitic stainless steels.
- Cold rolled austenitic stainless steel is another alternative.
- These alloys are wholly austenitic and exhibit high strength at elevated temperatures.
- The basic composition of austenitic stainless steels is 18% chromium and 8% nickel.
- Most austenitic stainless steels are used in corrosive environments.

Origin

Early 20th century: from the name of Sir William Roberts- Austen (1843–1902), English metallurgist, + -ite¹.
