Analysis of Wrought Iron Metal Part of Cupola Construction in the Main Railway Station Plzeň from 1907

Abstract:

The paper describes the metallographic analysis of a metal part from the cupola construction in the Main Railway Station in Pilsen. The station in the Art Nouveau style was completed in 1907. The part was screwed to a vertical column and used as a pulley, probably for the transport of other parts. The cross-section consisted of visible bands. The microstructure was heterogeneous, formed by connected individual bands, ferritic structure predominated, but in some bands it was ferritic - pearlitic. The structure contained both minor inclusions and complex elongated inclusions consisting of grains and binder - their composition was determined by ED microanalysis. The analysis showed that it is a wrought (puddled) iron with a considerable amount of slag, which was produced with technology used in the 19th century. However, at the beginning of the 20^th century, modern steel production methods were used for profiles and thus it is unclear whether this screwed part for manipulation represents the whole construction.
