SUMMARY

This discussion focuses on the search for comprehensive hardness values for materials such as Polycrystalline Boron Nitride (PCBN), Molybdenum, Tungsten Carbide, Diamond, H13, B4C, SiC, and Al2O3. Users have noted that while www.matweb.com provides some hardness values, it lacks data for certain materials, particularly PCBN. A recommended resource is the "Handbook of Refractory Carbides and Nitrides," which cites a Vickers hardness of 0.08-0.09 GPa for hot-pressed boron nitride.

PREREQUISITES
  • Understanding of Vickers hardness testing
  • Familiarity with material properties of PCBN and other hard materials
  • Knowledge of refractory materials
  • Basic research skills for locating material data
NEXT STEPS
  • Research the "Handbook of Refractory Carbides and Nitrides" for detailed hardness values
  • Explore additional databases like ASM Handbooks for material properties
  • Investigate the hardness testing methods for various materials
  • Learn about the applications and uses of PCBN in industrial settings
USEFUL FOR

Materials scientists, engineers, and researchers involved in material selection and hardness testing, particularly those working with advanced ceramics and hard materials.

Is there a website or book that lists hardness values for the following:

Polycrystalline Boron Nitride
Molybdenum
Tungsten Carbide
Diamond
h13
B4C
SiC
Al2O3

I've tried www.matweb.com, but they only have hardness values for some of these materials. I can't locate PCBN in their database either.

Thanks for any help!

You could try the Handbook of Refractory Carbides and Nitrides. They quote a Vickers hardness of 0.08-0.09 GPa for "hot-pressed boron nitride."
