Why ferritic and austenitic stainless steel are not heat treatable?
Ferritic and austenitic stainless steels are not heat treatable since "heat treatable" is taken to mean that martensite may be made to form with relative ease upon quenching austenite from an elevated temperature. For ferritic stainless steels, austenite does not form upon heating, and, therefore, the austenite-to-martensite transformation is not possible. For austenitic stainless steels, the austenite phase field extends to such low temperatures that the martensitic transformation does not occur.
Quinching of n butyl litium?
Quenching of n-butyllithium involves adding a suitable quenching agent, such as alcohol or water, to stop the reactivity of the organolithium compound. The quenching reaction generates an alkane and the corresponding alcohol, effectively neutralizing the highly reactive n-butyllithium. Care should be taken during the quenching process to prevent any violent reactions or fires.
Why does quenching in oil produce different results than quenching in water?
The fluid for quenching is specific for each type of steel; choosing an inappropriate fluid lead to bad results.
Why cementite is harder than austenite?
Cementite is harder than austenite because it is a compound of iron and carbon with a well-ordered crystal structure, whereas austenite is a solid solution of iron and carbon with a disordered structure. The ordered structure of cementite provides greater resistance to deformation and makes it harder.
What is quenching in G M counter?
stopping the ionization cascade modern geiger-muller tubes use a halogen gas for quenching
What is austenite?
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.

What is the term given to the Sudden cooling of metal during heat treatment process?
quenching
What is austenite-cementite?
ledeburite
What is austenite and ferrite stabilizer?
Austenite stabilizers promote the formation of the austenite phase in steel, such as nickel and manganese. Ferrite stabilizers, like chromium and silicon, promote the formation of the ferrite phase in steel. These elements help control the microstructure and properties of the steel during cooling.
How do you spell quenching?
That is the correct spelling of "quenching" (eliminating, extinguishing).
Quinching of n butyl litium?

Care should be taken during the quenching process to prevent any violent reactions or fires.
How internal stresses are induced during quenching?
they simply ar. just by thermal and struxtural means
What are the units of the quenching constant in the context of fluorescence quenching?
The units of the quenching constant in the context of fluorescence quenching are typically expressed as reciprocal concentration per unit time, such as M-1s-1.
On quenching high carbon steels get hardened but austenitic stainless steel dont why?
The metallurgical transfer motion behaviour during quenching is influenced by cooling rate, carbon concentrration , alloying elemnts and stress
What is a titration-quenching?
Titration quenching is a process where a substance is added to a solution to stop a chemical reaction or change in pH during a titration experiment. This substance helps to stabilize the solution at the endpoint of the titration, ensuring accurate results.
What is 'Quenching?
Color quenching is the attenuation of photons produced by a scintilator due to absorption and scattering. This effect, combined with the chemical quenching (attenuation of the transfer of energy from the solvent to the scintillator gives the total quenching effect of the scintillator/solvent mix.
