Opis:
With the populist tide on the rise, comparisons of contemporary right-wing governments to fascist regimes are increasingly common. The rise of the populist right-wing politics has created a number of reactions, using either new or established forms of political resistance. One of such examples is the anti-fascist movement whose strength grows in many national contexts. The recently observed political swing to the right results also in a radicalization of politics. Radical actors intersect and cooperate with moderate ones, influence one another and bring new ideas and repertoires of contention to the streets and into mainstream politics. This trend can be observed in Poland where the 2015 elections (presidential and parliamentary) resulted in the radicalization of the mainstream discourse. This article focuses on the case study of the broadly understood anti-racist movement in Poland that has recently had to remodel itself to face new challenges – in particular the institutionalization of xenophobic rhetoric and the growth of the far-right sector – and has undergone substantial changes in general. The article presents the internal radical- moderate dynamics within the specific context of the anti-fascist movement in Poland. In particular, it explores the role of changes in political opportunity structures for the reinvigoration of the anti-fascist movement in Poland, radicalization in some of its sectors, and change in its priorities and focus.

Opis:
The results of tests and examinations of the microstructure and mechanical properties of cast steel used for large-size slag ladles are presented. Castings of this type (especially large-size ladles with a capacity of up to 16 m3) operate under very demanding conditions resulting from the repeated cycles of filling and emptying the ladle with liquid slag at a temperature exceeding even 1600°C. The changes in operating temperature cause faster degradation and wear of slag ladle castings, mainly due to thermal fatigue.The tests carried out on samples taken from different parts/areas of the ladle (flange, bottom and half-height) showed significant differences in the microstructure of the flange and bottom part as compared to the microstructure obtained at half-height of the ladle wall. The flange and bottom were characterized by a ferritic-pearlitic microstructure, while the microstructure at the ladle half-height consisted of a ferritic matrix, cementite and graphite precipitates. Changes in microstructure affected the mechanical properties. Based on the test results it was found that both the flange and the bottom of the ladle had higher mechanical properties, i.e. UTS, YS, hardness, and impact energy than the centre of the ladle wall. Fractography showed the mixed character of fractures with the predominance of brittle fracture. Microporosity and clusters of non-metallic inclusions were also found in the fractures of samples characterized by low properties.
