Why is ferrite very low solubility of carbon while austenite has high solubility of carbon?

it is a solid solution of carbon and iron. The carbon present is only .02% ,solubility of carbon in alfa-iron is .02%.It is pure iron at room temperatue.It has BCC structure.The inter atomic space are very small,thus spherical carbon atoms can not be accommodated in irons atoms.That is why solubilities of carbon is very less.The maximum solubility is .0218% at 727 C at room temperature the solubility is only .008%

Why does the solubility of carbon in steel increase while heating?
Steel is mainly Iron with small amount of Nickel or/and chromium, carbon content of steel is about 2.5%. The increase in temperature increases the distance among the Iron atoms so carbon become accommodated easily in material.
Is the solubility of solids in water independent of pressure above solution?
Generally, the solubility of solids in water is not significantly affected by pressure above the solution. However, solubility can be influenced by certain factors such as temperature and the presence of other solutes. Therefore, while pressure may have a minimal impact on solubility, these other factors are typically more influential.
Why is it necessary to filter the benzoic acid solution while hot?
At low temperature it has poor solubility and would crystallize out
Is carbon soluble or insoluble in water?
Carbon dioxide is soluble in water, in which it spontaneously interconverts between CO2 and H2CO3 (carbonic acid), however if you get a pipette full of CO2 then sqeeze it up your bum you could actually know the answer to this question, but the CO2 mixes with the bum cheese, the result may create seaborgium (Sg). This element is highly poisonous to donkeys but you may be tempted to ride one half naked while getting a midget and your girlfriend to smother honey all over Prince Charles.Chin Chin!
Is carbon and carbon monoxide the same?
No - carbon is an element, while carbon monoxide is an oxygen atom attached to carbon, turning it into a gas which is quite toxic.
what is the difference between Pearlite and 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.
How do I convert a Ferrite number into a percentage?
While there is no direct correlation, with higher ferrite numbers ( >30) a factor of 0.7 can be applied to produce % ferrite.
What is iron carbon diagram?
A diagram based on the different percentages of carbon and iron. It shows the different grain structure in the materials created and different melting and "mushy" stages of the material at certain temperatures. Here is one: http://www.sv.vt.edu/classes/MSE2094_NoteBook/96ClassProj/examples/kimcon.html The metastable iron-carbon phase diagram, however, is used when studying the microstructures of steels (both carbon steels and alloy steels), as well as various heat treatments. Here is a detailed description of the metastable iron-carbon phase diagram: http://www.calphad.com/iron-carbon.html
Difference between stainless steel and duplex stainless steel?
dublex ss has 22% or more but ss has 18%cr or less the main difference is that duplex is a mix of a ferrite / austenite structure approx 50%/50%, and so the name "duplex" while stainless steel has just one structure, for example the 18/10 is an austenitic.
Why sulfur is soluble in carbon disulphide but not in water?
SOLUBILITY OF SULPHUR IN CARBON DISULPHIDE:Because carbon disulphide and sulphur both are non polar molecules therefore, sulphur is soluble in carbon disulphide while water is a polar molecule and not allow sulphur to dissolve
What is difference between apparent and intrinsic solubility?
Apparent solubility represents the solubility one observed during the experiment while the intrinsic solubility meant to the real or true solubility.
Why does the solubility of carbon in steel increase while heating?
Steel is mainly Iron with small amount of Nickel or/and chromium, carbon content of steel is about 2.5%. The increase in temperature increases the distance among the Iron atoms so carbon become accommodated easily in material.
Is pentanol water soluble?
The OH group makes it slightly water soluble while the carbon group resists solubility. The 3-pentanol molecule is slightly water soluble.
What is ferrite number?
Ferrite number is a measure of = Chromium & Nickel equivalent in an Austenitic stainless steel material. It should be between 3-7% max. Very low ferrite can lead to cracks. It is a measure of denoting the ferrite content in an stainless steel. Ferrite Number has been adopted as a relative measure for quantifying ferritic content using standardized magnetic techniques. The Ferrite Number approach was developed in order to reduce the large variation in ferrite levels determined on a given specimen when measured using different techniques in different labratories.The ferrite level is only important to assure minimum exposure to solidification cracking when depositing austenitic stainless steel weld metal. The lower ferrite number is better for corrosion resistance, while balancing higher ferrite content to avoid solidification cracking in the weld deposit. I would not worry about lower ferrite numbers for clad overlay welding, if no cracking is observed (Liquid Penetrant verification).
What happnes to the solubility of gas in a liquid after it is heated?
the solubility of a solid increases with temperature while those of gasesdecrease with rise in temperature.
How can solubility increase?
1) Strong solute-solvent greater solubility while weak solute-solvent attractions equate to lesser solubility 2) Temperature (for gaz high temperature decrease solubility) 3) Pressure for solubility gaz in liquid 4) Polarity of solvent: Like dissolves like
How many kinds of stainless steel are there?
Several. Ferritic, Austenite and Martensitic which can be further broken down into different types. . Austenite has the highest degree of corrosion resistance, ferritic has the best machinability while martensite is the most suitable for objects that need to be hardened. Some examples of martensitic stainless steels are 440c, Ats 34, Cpm s30v.
