No, there is not austenite around at room temperature. This gamma phase of iron alloys only appears at elevated temperatures (ball park - a bit over 700 °C). Once the alloy cools below the critical temperature, carbon diffuses and the steel takes on different characteristics -- and is given different names. It is possible to quench steel to get its metallic crystal structure to "set quickly" and bring out certain characteristics (notably hardness), but (again) we give this material a different name. To cite one characteristic of austenite, it is nonmagnetic. It is above its Curie temperature and will not "hold" a magnetic field after the source is removed. A link is provided below. It might be possible to have steel alloys with a micro-structure similarto austenite at room temperature, but the characteristics are different and the alloy is called by a different name. But the mobility of carbon atoms within the structure is a definitive characteristic of austenite. And this only happens at elevated temperatures.

What are the phases of eutectoid steel at room temperature?
The lowest temperature at which austenite transforms into ferrite and cementite. Steel with 0.77 percent carbon transforms at this temperature. Learn more abouteutectoid temperaturein the classHeat Treatment of Steel 230below.
Which material is a liquid at room temperature 25C?
Mercury (Hg) is liquid at room temperature.
What is partial annealing?
Annealing is a process in which a material is treated to re-crystallise and get into its stable form, i.e to align its axis to there characteristic directions. here sample is ist heated to a certain temperature,maintaines at that temperature for a specified time and then allowed to cool down to room temperature. The process involves recrystallization to form new, strain-free grains, and then grain growth of grains in the metal (or material).

What is normalises?
Normalizing Is a heat treatment process (predominantly used on Steels) It makes the material softer but does not produce the uniform material properties of annealing. A material is normalized by heating it to a specific temperature and then letting the material cool to room temperature outside of the oven. This refines the grain size and improves the uniformity of microstructure and properties of hot rolled steel. Normalizing is used in some in the production of large forgings such as: railroad wheels and axles and on some bar products. The process is less expensive than annealing.

What room temperature is copper?
You can put copper in any room you like, and it will be able to match the temperature of the room through a normal heat transfer process, just like any other material.
