3. Stiffness — resists deformationToughness — resists failure, even after deformingStrength — resists both deformation and failureDuctility — deforms before it breaksBrittleness — breaks before it deformsHardness — resists dents, scratches, and other permanent changes under compressive force(Malleability-Elasticity-Plasticity…)6 Properties of Materials

5. NOT a fundamental property of material i.e like Tensile Strength or DensityRockwell is a unit less value (like percentage)Vickers Load over Area / Pascals/ mPA-gPAResistance to Penetration

15. Light force (Baby) BrinellBe careful what you wish for! Yes we can do tests up to 187.5 kgfUS Thinks of Brinell as:500 kgf. to 3000 kgf. and 10 mm ballISO Thinks of Brinell as:1kgf to 187.5 kgf1mm, 2.5mm, 5mm and 10mm ball

20. Typical Knoop Traverse
21. Vickers/ KnoopAll testers come with Vickers indentersA Knoop indenter may replace it or HM200 machines can add a second indenter assembly

24. HM/HV Automation
25. HM 210/220 Type A TesterUses a digital filar eyepiece where the operator manually determines the end points of the indentation.A CCTV can be added for easier viewing.
26.
27. HM 210/220 Type B TesterA Type B tester deletes the control panel from the tester, removes the filar eyepiece, and all measurement is automatically performed by the software. Manual on screen measurement is possible.A Type B utilizes the standard mechanical stage on an HM200 testers and will interface with an optional mechanical stage on the HV100
28. HM 210/220 Type C TesterType C Tester is similar to a Type B tester with the addition of a motorized X-Y Stage.50x50mm or 100x100mm is available.The Type C does not include automatic focus!!!
29. HM 210/220 Type D TesterThe Type D tester is a fully automatic testing system with a motorized X-Y and Z axis.Complex programed patterns can be run without supervision.

32. ASTM E18 Key PointsTiming!Test on one side of block only!Spacing of 3 diameters between indents1 HR value is 80 millionths travel
