Nanoscratch Testing


  • Nanoindentation with EBSD
  • Films & coatings
  • Temperature dependent mechanical properties
  • Ultra-hard materials & large structures


  • Simultaneous testing & imaging
  • Advanced, high performance system
  • Ideal for SEM and FIB/SEM
  • Modular system; upgrade with a whole range of testing techniques

Testing Modes



  • Precise positioning
  • Nanoscale load and depth control
  • Determine fundamental mechanical properties eg hardness and elastic modulus
  • Suitable for a wide variety of materials

Tensile Testing


  • Direct-Pull and Push-to-Pull (PTP) testing
  • Test dog-bone specimens, thin films and nanowires
  • Measure stress-strain behaviour in-situ
  • Study low dimensional materials not easily tested with traditional methods.

Bend Testing


  • Align loads and measure accurately with SEM imaging
  • Measure bending stiffness and fracture toughness
  • Single-phase, composite or layered materials.

Compression Testing


  • Compress pillars, particles and other small scale structures
  • Measure stress-strain behaviour and yield properties
  • Simultaneously observe deformation mechanisms in real time
  • Check tip alignment with SEM imaging

Optional Upgrade Modes

  • Heating up to 800°C
  • Electrical characterisation
  • Push-to-pull device
  • nanDynamic mode
  • nanoScratch mode


Modular Design

The PI 88 is modular so it can be upgraded with Hysitron’s full range of testing techniques as you need them in future, including:

  • 800°C heating
  • Scratch testing
  • 5-axis sample positioning
  • Electrical characterisation
  • Dynamic fatigue testing
  • Interchangeable extended range (500 mN, 150 µm) transducer

The PI 88 attaches to the SEM sample stage, and can be removed at any time.

Both 3-axis (X, Y, Z) and 5-axis (X, Y, Z, tilt, rotation) sample positioning stages are available:
