Hi Hasan. This is a slight simplification as it depends on the material. If we take tungsten (W) as an example, there are 6 {110} slip planes and 12 {211} slip planes. It is still quite hard to visulalise, but hopefully this image will help: images.slideplayer.com/13/3815885/slides/slide_4.jpg Note that alpha iron has an additional 24 {321} slip planes.
@@EngineersAcademyLTD Unfortunately that image does not include a coordinate, so in comparison of the respective, albeit unmarked, {110} and {211} planes, {211} is both drawn confusingly, and I believe wrong, as the {211} plane should intersect the x-plane within in the unit cell, instead of outside. I believe a {122} plane was drawn instead of a {211} plane. Just to help people avoid confusion.
@@ianvangiesen2523 thank you for you feedback. I agree it is certainly difficult to visualise, but for our programmes the important thing is how the material properties are affected by the presence of slip systems. It is probably not a sufficient explanation for someone studying material science, as an example.
Is there a visual explanation somewhere that clearly describes (even if tediously) the closest packed planes and slip systems/planes for the BCC lattice? It's pretty frustrating how easy it is to visualize the fcc and hcp compared to the bcc.
Thanks Ian. Unfortunately I haven't been able to find anything, despite spending quite a bit of time searching. Please let us know if you find anything.
Thank you from Turkey 🇹🇷🇹🇷
Thank you sir🙏
Thank you!
How do you determine the number of slip planes in the BCC structure? I don't see how there would be 18 planes.
