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%
At what temp does it take to dissolve salt slower?
The solubilty decrease at low temperatures.
What is meant by low-medium-and-high-carbon?
The terminology low carbon, medium carbon, and high carbon usually refer to different alloys of steel having differing ratios of carbon to iron in the alloy (ranging from very little to very much respectively).
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).
Does carbon dioxide dissolve in ethanol?
Carbon dioxide has a very low solubility in ethanol.
What is the percent yield for carbon disulfide if the reaction of 40.0g of carbon produces 33.0g of carbon disulfide?
This yield is very low - 13 %.
What is Hyper Annealing?
This process was originaly developed to enable relay and solenoid components to be made from low cost steels. This process reduces carbon and nitrogen levels in the steel resulting in parts having high permeability, low magnetic aging, large ferrite grain size and bright finish.
Why does carbon-14 not harm us when you breathe?
very low concentrations
What were the carbon dioxide levels during the ice age?
very low
What is the hardness value for carbon?
the hardness vlaue of carbon very much depends on the value of the hardness of the carbon. if it is a high value then the hardness is high however if it is a low value then it is a low hardness helpful??? :D
What is low carbon steel and high carbon steel?
Low carbon steel is steel with low carbon. High carbon steel is steel with high carbon
Is carbon dioxide a solution compound or element?
CO2 is a compound of carbon and oxygen, very stable, in a state of low chemical energy, with very little value.
