Matrix Steels K888 and CPM 1V - Age of the Hyper Steel?

Bohler released a new non-stainless powder metallurgy steel called K888 which is advertised as having extremely high toughness even at hardness levels of 64 Rc. I tested it as well as the very similar, older CPM-1V to see how they compare with other knife steels.

Vanadis 60 Super High Speed Steel - 70 Rc and 7% Vanadium
Просмотров 5 тыс.3 месяца назад
New study by myself and Malachi Chou-Green looking at Uddeholm's Vanadis 60, a powder metallurgy high speed steel that reaches 70 Rc and has 6.5% vanadium. We tested its properties and found how it compares to other super high speed steels like Maxamet and Z-Max.

    Congrats Dr. Larren! Not only have you created one of the neatest steel formulations to have ever existed, but you have undoubtedly influenced steel manufacturers to innovate in ways they probably never would have, now that you have proven that the give and take of toughness/wear resistance/ and corrosion resistance can be be tweaked to yeild results better than they should, if the formulation is just right. ^ probably the longest sentence ive ever written. 😂

    I am a complete innocent when it comes to metallurgy. I learned to use a lathe and mill for fun in college and someday I would like to do little metalworking in my garage as a hobby. I have a question: once a coupon is shaped and you are doing these tests and looking at the internal crystal structure, does working the steel (hammering, stretching, folding) have any effect on that structure? Again, sorry for being ignorant but I am very curious.

  • @me2bfc
    @me2bfc 2 дня назад

    Any evidence the Damascus cutting effect happens when using two steels with different wear resistance? Say something like 1084 and 52100? Hardness won’t be different but wear might be different enough to show the effect. Then again, the difference between 1095 and pure nickel is greater than that of 1018 and 52100, so it might not be noticeable if the difference isn’t enormous.

  • @jackmclane1826
    @jackmclane1826 2 дня назад

    When you have a material with randomly occuring defects - like every type of damascus (forge welding can never be completely defect free in a large area), toughness becomes depending of the material volume under test (Weibull distribution). If the test piece cut out of a sheet is - by chance - defect free, it may do well in testing. If there is a defect, it will fail early. So nobody knows if 1084/15N20 is a tough combo, or just picked a good part for testing.

    • @KnifeSteelNerds
      @KnifeSteelNerds 2 дня назад

      This assumes that multiple samples didn't have defects. But we found defects and it still tested well, so the presence of defects is not necessarily a guarantee of poorer performance. In this case the distribution and orientation of the defects in the 1084/15N20 did not appear to be deleterious for the toughness test.
