Archaeometallurgical Study of Argentinian Railway Parts

A recent metallographic and historical analysis of two parts from the Buenos Aires to Pacific Railroad railway looked at possible manufacturing techniques of the parts in question. The information collected is useful for comparison with techniques and materials used at that time as well as with current techniques. The analysis questioned whether the material itself has varied or evolved from the metallurgical point of view, and confirmed the quality of raw material used to construct the historic railway line.
