Follow Up Testings |
Material testing comprehends different
testing methods to determine the material properties of
samples or parts under mechanical, thermic or chemical conditions
to which a part is subjected.
The material is thereby inspected concerning
its purity, defectiveness and working stress capacity. Material
testings can be subdivided into two main categories: destructive
testing and non-destructive testing.
Destructive Testing
During the destructive testing of materials
the parts are examined for chemical and physical characteristics
and thereby destroyed or changed (at least on the surface).
The substantial methods of the destructive testing are:
Mechanical
-> Hardness testing according to Vickers, Brinell,
Rockwell
-> Tensile tests
-> Shear test
-> Compression test
-> Beam impact test
-> Bending test
|
Chemical
and thermic
-> Crystallography/Metallography
-> Jominy test |
Non-Destructive Testing
During the non-destructive testing of
materials the quality of a work piece is tested without
damaging it.
Classical
non-destructive testing methods are:
- > Microscopy / Metallography
- > Acoustic emission analysis
- > X-ray analysis
- > ultrasonic testing
- > eddy current test
- > magnetic particle test
- > penetration test
- > visual check/visual examination
