Hardness testing (Brinell, Vickers and Rockwell test method simply explained)

[@_Meena1230]

Master piece to understand the hardness test..Kudos to the team that prepared it to share and transfer knowledge to the next generation...

[@tec-science]

Thank you very much. The "Team" is just me, but thanks! 🙏🏽

Only video you need to watch to understand hardness testing

[@death_parade]

You earned a new subscriber. Severely underrated channel.

[@tec-science]

Thank you 🙏🏿

[@Kottam_Yallawa]

This video is better than most of the paid contents out there 🤝

[@tec-science]

Thank you!

[@jdextlab]

Nice video....needed to refresh my memory from materials science class because now I need a hardness tester at work

[@samreddymukeshreddy5061]

best tutorial on youtube deserve more views and likes

[@joaosoares4893]

very good video, helped me with my materials class

[@cookiemaria780]

Really wonderful video! This helps us university students so much you cannot imagine! Your entire channel is so great! Thank you! I look forward to more materials science videos!

[@tec-science]

Thank you very much for your kind words

[@TheFlemishNut]

Absolute master piece

[@hakanatalan8446]

Thank you very much for your video. I really enjoy, appreciate the content, it is explained very smoothly. Thank you Again

[@tec-science]

Thank you very much 🙏🏼

[@daniloskrrr8979]

Amazing explanation and presentation as well😊

[@tec-science]

Thank you!

[@kisekkabarnabasi9789]

great tutorial

[@tec-science]

much appreciated

@26:00 , on various websites, major load is mentioned as 150kgf, 100kgf and 50kgf instead of 140, 90 and 40 . Which one is right??

[@jarekferenc1149]

There is no doubt here: the total loads 150, 100 or 60 kgf consist of two components: preload (F0) of 10 kgf + main load (F1) of 140, 90 or 50 kgf. See the EN/ISO 6508-1 standard.

[@JinRi-b6h]

Can anyone recommend a machine brand name/model that could accommodate me for this three tests? Thank you.

[@AmaraNS-iw6og]

what a great videos

[@Unknown-ry2rl]

Thanks for information

[@fooziyong6957]

May I ask whether uneven surface is suitable for this hardness testing also ? Thank you

[@tec-science]

I don't think that it is suitable because you don't get valid and comparable results

[@Kottam_Yallawa]

Need a video on the topic heat treatment

[@tec-science]

I haven't created a video about that topic yet but you will find information on heat treatment on my website

[@simon_faucher]

Great video, very interesting and informative:) what is the name of the machine used?

[@tec-science]

Thank you very much for the appreciation. I have no idea what machine this is supposed to represent. I looked at some reference pictures and then constructed the whole thing roughly for the 3D animation.

[@simon_faucher]

@@tec-science no problem, I suppose these are way out of my budget anyway😅 thanks again for the video!

[@fuste_woodtech]

Thanks!
