slip system, Tantalum, Niobium, texture, microstructure

Many scientists believed that he had only discovered an allotrope of niobium, an element that is chemically very similar to tantalum. The issue was finally settled in 1866 when Galissard de Marignac, a Swiss chemist, proved that tantalum and niobium were two distinct elements. The first relatively pure samples of tantalum were produced in 1907.
