- n. A nonmagnetic solid solution of ferric carbide or carbon in iron, used in making corrosion-resistant steel.
Century Dictionary and Cyclopedia
- n. A constituent of steel, obtained by quenching high carbon steel from a temperature of 1000° C. in a menstruum such as iced brine, which will produce very rapid cooling. It is probable that austenite is a true solid solution of carbon in iron, and that martensite, troostite, and sorbite are stages in the decomposition of the solid solution — that is, are intermediate steps between austenite on the one hand and pearlite on the other. On the subject of the constituents of hardened steel there exists at the present time a great deal of confusion in the nomenclature, nor is it possible to say definitely what is the true nature of any of these constituents.

Etymologies

Examples
“He suggested to me a theoretical problem left over from his work during the war on the cooling of steel through the austenite-pearlite transition, and I learned a fair amount of metallurgy in order to understand the physical basis of the phenomenon.”
“In order to produce quick and intense carburization the iron should preferably be above its upper critical temperature or 1,600°F., -- therefore the carbon absorbed immediately goes into austenite, or solid solution.”

“There are several theories to explain this reaction, but generally it is only necessary to remember that in hardening we quench steel from the austenite phase, and, due to this rapid cooling, the normal change from austenite to the eutectoid composition does not have time to take place, and as a consequence the steel exists in a partially transformed, unstable and very hard condition at atmospheric temperatures.”
The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel
“The structure is then austenite and the air-cooled structure of this steel is martensite.”
The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel
“The growth is continually destroyed by the hammering, which should consequently be continued down to the upper critical temperature when the austenite crystals break up into ferrite and cementite.”
The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel
“Chromium steels are therefore capable of great hardness, due to the rapid cooling being able to retard the decomposition of the austenite.”
The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel
“If a piece of steel could be cooled instantly, doubtless austenite could be preserved and examined.”
The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel
“Higher percentages of nickel change the martensitic structure to austenite, the steel then being non-magnetic.”
The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel
“In the ordinary practice of hardening steels, the quenching is not so drastic, and the transformation of austenite back to ferrite and cementite is more or less completely effected, giving rise to certain transitory forms which are known as "martensite," "troostite," "sorbite," and finally, pearlite.”
The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel
“However, if the heating has gone above the critical very far, the austenite crystals start to grow; a very short time at an extreme temperature will cause”

fbharjo early type of stainless (corrosion resistant) steel. Was it allegorically well-named after Jane Austen who was renown for her steadfastness and staying power? No matter. She is a pearl(ite?(light?))in her own write. Jan 17, 2011
