The manganese crusts need machines that can cut into steep underwater cliff faces. Tjåland says there are several possible solutions. ... One big unanswered question is how much sand, particles, and 'dust' will be churned up by the mining machines. It is also unknown how much they will affect life on the seabed, at active …
Manganese, along with nickel and cobalt are widely used as an austenite forming and stabilizing elements [44,45,46]. The admixture of manganese is not a carbide former itself, it rather increases carbon solubility in Mn-Fe alloys . That allows cementite matrix to precipitate during cooling of the cast steel, and thus constrain the growth of ...
