Aluminum Tornado for Metal Matrix Composites (MMC)

What are Metal Matrix Composites and how are they made? Here we experimentally show some of the ways how to process aluminum. We melt aluminum by induction heating, stir it with rotating permanent magnets, and then cast it in mold.

Very informative video, really enjoyed it!

[@Brute4rce1111]

I love this field of research! Thank you for posting this. Would love to see more covered on the topic of metal matrix composites👍

[@pgurung001]

Awesome experiment and presentations. Eagerly waiting for more MHD contents. What power source do you use for the induction heating and frequency? Also could you not use an induction coil with time varying current as an alternative to the rotating magnet?

[@MHDTechnologyLaboratory]

It is a high frequency (up to 20 kHz) power source by German company Eldec. Model is MFG 20 with maxiumum power of 20 kW. Here 17 kHz frequency was applied to melt aluminum.
In principal yes, you could use induction coil with time varying current. Though it should be different than coil melting the metal since a different frequency must be used and ideally different shape of inductor aswell.

I am also working on the AMC. Thank for sharing the great information love from India ❣️.

[@chir0pter]

Very cool. We've barely begun to explore so many cool opportunities in materials science and already we're being mandated off from moving atoms into just moving electrons (EVs and such). Here's hoping the mandates fail and we continue to hone the state of the art in moving atoms at high speed reliably

My research topic was on MMC.
When i was under PG project

[@thomsn838]

Great video, im writing my bachelor thesis on MMCs as we speak. Will you make more videos abou MMCs?

[@MHDTechnologyLaboratory]

Thanks. Unfortunately, I won't make any videos about MMCs in near future.

[@mediwise2474]

PL HELP

[@mattman8685]

You guys do for a job that of which I would do for free for the fun of it! Great work!

How aluminium alloy can be mixed with Alumina to form MMC

[@nothing3779]

Hi sir, can you tell the best reinforcement for the aluminum matrix.... please it helps me a lot

[@fetusness]

Thank you for sharing this knowledge brother

[@williamcarter1532]

super helpful

[@SURYA_Things]

Pls give suggestion for which reinforcement is used for A356 ....

[@mmedEd]

Hello, What do you use for the ultrasonic degassing? from where can I buy it, Thank you.

[@mahdihosseini6361]

Very informative video thank you

[@jinilpatel8099]

I have query that stirring is done in semi liquid phase to avoid density problem .now when pouring is done it is in liquid phase or semi solid liquid phase?

[@Creomortis]

That was sick, make more videos of stuff

[@user-um9sl1kj6u]

What about steel?
I realize sluminum melts at a lower temperature, but steel is stronger

[@slevinshafel9395]

have you try to make carbon fiber matrix? instead use resin wich melt at 300ºC in the best scenario. use aluminium or magnesium to fuze the carbon fiber fabric. or will melt the fibers?
i was thinking in impregnate fabric with powder layer by layer until we get 3mm or 5mm thicknes and after that melt it and press them toghether. Or use melt aluminium and impregnate the carbonfiber fabreic, i hope dont have to much surface tension between this 2 materials and can be fused like resin.

[@MHDTechnologyLaboratory]

We have not worked with carbon fiber matrix. All our experiment have been with powders and mostly with aluminum as the base material.

CAN YOU HELP ME ? I HAVE SAME QUESTION
