@Rajesh Prasad lectures on Materials Science then the area of the grain boundary should be the one divided by 2
@Introduction to Materials Science and Engineering kindly help here sir ,pi(di)^2 is the surface area of one whole grain, it's not the grain surface area boundary ,why are you then dividing by 2 to get the grain surface area boundary per grain?

Dear Professor Prasad,How can the misorientation between two grains be compensated after grain growth? Does the smaller grain dissolve and contribute to the growth of the larger grain? Then, what is the difference between coarsening (Ostwald ripening) and grain growth?
Sir ,Why volume is taken as d^3/6?
thank you! would you please explain to me what is the relation between increasing the energy and reducing grain boundry surface area ?
Sir, please can you tell me the difference between coarsening and grain growth. Are these two phenomenon same or there is some difference between these two ?
Sir, wondering if this process continues through some of the cooling stage, or if it only occurs when the material is being held at a constant elevated temperature.
Thank u sir for your amazing explanation...this will help students like me Pls keep it up
Professor Rajesh Prasad, thank you very much for the explanation! Please could you explain why the grain boundary is not the volume of a sphere? And why is the grain boundary per grain only half of the area? Thank you in advance.
Grain growth occur when we maintain temperature above recrystallization temperature.. Grain boundaries also decrease at lower temperature and it is also driving force in this case.. So why grain growth can not occur at room temperature
sir,it is very clear that the finer grains contributes to larger strength.But when we talk about DUCTILITY AND TOUGHNESS ,then what is the relation of grain size to these two properties...DO finer grains are more ductile in any cases...its very confusing sir..plz help....Also,in many sources finer grains have high brittleness and less toughness ..why it so?
Sir,why should the volume remain constant?
good Lt
super explaination....thank you ..sir ...

Does ostwald ripening happen in colloids too?
U deserve million views
