Why do dendrites form in metal alloys?

[@sheldrickotieno7541]

you just explained a very important chapter in material science and engineering ..now i can walk in an examroom with confidence ! thanks!!

how did it go

[@toantruong2581]

Thanks Dr. Taylor. Big fan of your podcast. Keep it up!

[@TaylorSparks]

Thanks homie!! We've got a bunch of great episodes coming soon

[@matteoguatta3294]

Simple but effective explanation thank u

[@beyzayigit1912]

Thanks for the video. Just want to ask you sth. About dentritic growth you say the tip is going to melt. What ı don't understand is if liquid's temperature can melt the solid why does it melt only the tip? İsn't is supposed to melt whole solid? From the cambridge web site it says the rate of solidification of tip lowers so it is caught up. İs it still okay to say the tip melts?

What will be the effects of pores on solidification modes?

Thank you!

Could you add the link to the website you used into the description? Would really appreciate it, love the video!

Hey I was just wondering why some dendrites look like trees and some just form like T shapes

Bro you are the best.

Glad to help!

Weird comment, but I don't disagree!

[@haythamomar3647]

unfortunately, that's not the real phenomenon or mechanism observed in alloys, where although having a positive thermal gradient led to the formation of dendrites. addition of this small note would be useful for material science and engineering students. thanks a lot

[@TaylorSparks]

Thank you! Can you send more info?

[@haythamomar3647]

@@TaylorSparks I mean by positive gradient the case of Constitutional supercooling.
