Techniques for Strengthening Metals

[@JoshV74656]

I'm an engineer of 20 years using these videos as a bit of a refresher for my 2021 training goals at work and they are very clearly put together and educational, much appreciated.

This video is great with concise explanations and clear graphics so it mproved my metallurgical knowledge 10-fold. I wish I could get all her lectures here. She is very good. Thanks Brian

EXCELLENT VIDEO AND EXPLANATION

[@anuradhaabhayawardhana3860]

Thanks for sharing this valuable information. But I have one question. I was asked to maintain the temperature at 530 C - 540 C for aluminium alloy. When compared to the melting point of aluminium, 660 C it is way higher than the limits for the recrystallization temperature as the lecture. Could you please explain this?

thanks for doing this. where can i find the ppt

Hi Tonya, thank you for your videos. I have one question, 16:20 since all the units are in mm - why 2.1 MPa is not converted into 2.1x10^9 (N/mm^2)? Thank you

can i have the other lectures regarding to strengthening please

[@ebukaonyedinma2186]

thank you for this video. I am a little confused though. You mentioned that one way of strengthening a material is to reduce the grain size so that the material doesn't slip as much. Why then will the HCP material be more brittle given that it has less slip systems and as such, should slip less. Does having less slip systems not achieve the same aim as reducing the grain size?

[@tonyacoffey5568]

When you strengthen a material, often it does become more brittle. There is a distinction between strength and ductility. Ductile systems deform but do not break. Many brittle systems break when they deform, but they do not deform easily because they are strong.

@@tonyacoffey5568 oh yeah. Thanks a lot. I love your videos
