i have massive respect for people who have done this kind of work before. it is the most tedious, painstaking, annoying process you will ever have to do in a lab and it drove me crazy. imagine washing dishing at a restaurant, but the dishes will never get clean without 100% of your focus for multiple hours.
i went to bed most nights hearing the whirr of the machine and visualizing the spinning of the cross section sand papers.... man i don't miss it.

I was recommended this video by my teacher, totally worth the time.

[CTSecrets]

How many of you are here because of lab of material science !!

[WeldNotes]

Thanks so much for making your videos available! They are great!

[muhammadahmad]

By watching this video i have been able to check the grain size of metals. the thorough explanation helped me a lot.

This video is very interesting and well executed: I was looking for some videos which shows practically what I am studying theorethically in the metallurgy course, and this is perfect to see how these techniques are applied in the real world :)

Nice presentation and explanation. Glove up when using chemicals as a caution.

[citizencitizen]

Keep on doing it....It's very useful for me...Thanks for the team...

This channel is epic, biblical, mind-blowing. You guys are the best. Thanks for the absolulety HIGH QUALITY CONTENT.

[akashdileepgandhi]

Any video on colour or tint etching will be highly appreciable

[kodaiimman]

What do you mean by chemical etching? what kind of solvent do you use?

[michellep]

Great video! I would've liked to see some PPE.

Hi, informative video, I have a question though:
How to break a small sample out of a resin? if you have to perform hardness and you don't want the resin to effect the measurements, how shall I proceed to take out a sample from resin?

[ΘΩΜΑΣΚΟΥΜΑΡΗΣ]

Congratulations your presentations are very good. I would ask you if you could put subtitles for people with hearing problems. Congratulations again and thanks for your effort.

[uwofracture]

Very instructive. Thanks for sharing :)
What are the best etchant for brass and Aluminum?

[zomisintu]

Thanks for sharing thats interesting And very clean and fully furnished lab.
Where is it?
Do you Guys have a graduate program in metallography?
My major is on microstructure mainly on steel.
I really need to study more on this subject.

Cool video. I didn't know robots are running this lab :)

Are you still running Windows 2000 for the microscope ;D

[Victorator]

Excellent video! Which solution do you use to reveal the grains? Thanks.

[kokomanation]

I did all these in the university while studying mining and metallurgical engineering
