Pretty sure it is ferrite
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.
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.
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.
its a solid solution created when carbon steel is heated to red hot. also know as the alpha iron. during cooling of the steel it can transform into pearlite or ferite.
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.
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.
calcium ferrite is CaFe2O4
ledeburite
Pearlite is a microstructure formed in steel with a specific carbon content, characterized by alternating layers of ferrite and cementite, while ledeburite is a less common microstructure formed at extremely high carbon levels, primarily composed of cementite and austenite, and is brittle in nature.
The are three types of cementite which form in different ways. There's the primary that forms from crystalization from the molten iron above 4.3%C and below 6.7%C (line CD in Fe-Fe3C diagram), secondary cementite which forms from precipitation from austenite at the right side of the eutectoid point. And there's the tertiary cementite which forms as precipitation from ferrite alpha because of the falling solubility of carbon in ferrite as temperature goes down.
