New samples produced

Some of the prepared samples

The last weeks I was busy with preparing roughly 300 samples for the data base and the hardness measurements. Samples were made of eight different alloys, four different annealing times at 600°C in reduced atmosphere, cross-section and longitudinal section, and up to five different grades of deformation (cold rolling). And I have to admit that the rolling machine is just fantastic! The more arsenic the alloy contains, the harder it was to roll (not very surprising…) but I was fascinated by the squeaky sound the higher alloyed metal produced.
