IMPACT TESTING — HAMMERING OUT RESULTS
The selection of a specific material also depends on its deformation behaviour at varying temperature ranges. To establish the toughness of a metallic material at negative temperatures up to -80°C, we employ the impact test method. In this process, the specimen is first cooled to the exact testing temperature in a separate refrigerated circulator. In a pendulum impact tester with an automatic pendulum lift and automatic pendulum brake, the hammer then hits the centre of the notched workpiece.
Standardised impact testing in line with:
- DIN EN ISO 148-1
MATERIAL ANALYSIS — MAKING SPARKS FLY
Material analysis using spectral technology is about establishing the elemental composition of metals as a percentage. In our laboratory, we can flexibly test all current metallic materials that are based on iron, aluminium and copper. The vacuum spark emission spectrometer used for this process sparks off the surface of the specimen and produces a clear result to indicate the elements contained and their weighting.
METALLOGRAPHY — LOOKING DEEP BENEATH THE SURFACE
Structural analysis is used to analyse surface flaws and thermal treatment, even in the event of damage. Metallographic sections are produced in our sample preparation room and are then inspected so that their constituents can be identified. Using state-of-the-art microscopes during this process enables the analysis of the proportion of constituents, for example martensite or delta ferrite. It is also possible to establish the surface decarburisation and carburisation of the workpiece.
