What is austenitization?

Austenitization is the heating of iron to a temperature at which it changes crystal structure from ferrite to austenite.


Explain the effect of austenite and ferrite stabilizers?

In steels, alloying elements such as silicon, chromium, molybdenum, aluminum, titanium, niobium, etc., stabilize the (body-centered cubic) ferrite phase. These elements are referred to as ferrite stabilizers. Alloying elements such as carbon, nitrogen, manganese, nickel, copper, etc., stabilize the (face-centered cubic) austenite phase. These elements are referred to as austenite stabilizers.


What is trip steel?

TRIP steel is Transformation Induced Plasticity steel. It is a composite steel that consists of ferrite, bainite, martensite precipitants and restrained austenite. The austenite will transform into martensite when strained, thus increasing the strength of the steel. To stabilize the austenite you need to introduce alloy elements, usually Manganese.


What is the purpose of Ferrite test?

The amount of ferrite present in austenitic or duplex stainless steels is called "FN" or Ferrite Number. For austenitic SS, a small amount of ferrite will decrease the tendency for hot cracking during solidification. Company specifications should have a required FN range in their welding specs. Too low of a number may indicate that there are hot cracks. Too high of a number may decrease the corrosion resistance, or the ferrite can convert to sigma at higher temperatures. Ferrite is magnetic whereas austenite is not. Duplex SS nominally contains 50% ferrite/austenite, although the acceptable range for ferrite is much broader than exactly 50%. There are several ways to measure the FN. As mentioned by Metalguy, you can use a Magne-Gage. I have used a Severn Gage and a Feritscope.


What is retained austenite?

During martensitic transformation, even at absolute temperature, all austenite does not transform into martensite. Some austenite always remains, known as retained austenite.


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.


What is the difference between eutectic and eutectoid points?

Eutectic point is where a liquid eutectic composition cools sufficiently to solidify. Eutectoid point is where, within a solid, the material cools enough to undergo a phase transformation. e.g. austenite to cementite and ferrite.

What are the macroscopic and microscopic properties of stainless steel?

Microscopically (what we can see through an electronic microscope), steel is seen in a shape of grains, particules, beans, but the submicroscopic strcture of steel is its crystalline structure: the ferrite is Cubic centred, austenite is cubic faced centred and martensite is like a parallelogram.
