N2 - The production of industrial-near alloy samples is of major importance, as soon as laboratory tests need to be compared with industrial processes. Therefore, production facilities must be closely oriented to existing melting techniques, heat treatments and processing parameters. For this purpose, a master alloy is produced in a resistance heated furnace in 10 kg batches under different cooling parameters. For further alloy variation, small samples (100 g) can be remolten, alloyed and cast under vacuum or protective gas respectively using an induction heated furnace. The further process consists of an appropriate heat treatment and surface finish. Thereafter, rolling parameters can be varied in a small-scale rolling stand. Considering the final annealing step, various air-circulated furnaces and tempering baths are available. Testing these samples, it has been shown that comparisons considering grain size and microstructure as well as mechanical properties are valid.
