Automatisierte Probenpräparation an Kaltarbeits- und Kunststofformenstählen

In this article, the problems of sample preparation of annealed cold-work and plastic mold steels were gone into in more depth. Due to the characteristic microstructure, namely a relatively soft matrix with hard carbide inclusions, great problems arise with respect to quantitative analysis (e.g. purity analysis) of the section as the necessary quality can hardly be achieved with normal automatic preparation methods. The aim of this work is to optimise the preparation parameters for the two material groups on two chosen examples, in order to guarantee section surfaces as fault free as possible.
