The goal of this training course was the production and the characterization of two amorphous alloys, named metallic glasses too. The amorphous state correspond to a specific atomic structure which is very similar than the liquid structure but applied to a solid. It means that in standard condition there is no relative motion between atoms. The first one is an Fe-based alloy with the following atomic composition: Fe65-xCrxMo14C15B6.It was produced at the liquid state, by injection inside a cooled copper mould. The second one is an Zi-based alloy but its composition is kept secret. It was obtained by rapid quenching, using a melt-spinner system. Both of those processes have been analyzed on computer, during a thermal study, in order to obtain max and min-values of the cooling rate. The cooling rate is an important parameter which act directly on final structure, after solidification of the melted alloy. The knowledge of those values permit to qualify the amorphous state, before analyzing it with other test.
