Detailed Description
The ZHU/zwickiLine universal hardness testing machine is based around the zwickiLine materials testing machine. It can be used both for classical hardness testing methods (Rockwell, Vickers, Brinell, ball-indentation) and for the innovative instrumented indentation method for determining hardness plus other material parameters of metallic materials (Martens hardness, ISO 14577). In addition, cyclic indentation tests with increasing test load or indentation depth and partial unloading are implemented in the testXpert testing software.
Uses/Applications
Hardness tests employing indentation measurement, including:
- Martens hardness HM, instrumented indentation test
- Rockwell hardness scales A to K, N, T, plus HMR5/250
- Rockwell hardness scales R, L, M, E, K, a
- ball indentation hardness (for plastics)
- Vickers depth measurements HVT
- Brinell depth measurement HBT
