1. A method of producing a tantalum alloy that is resistant to aqueous corrosion, the method comprising microalloying substantially pure tantalum with Mo, the substantially pure tantalum comprising Ta-3W,
wherein (i) the microalloying is performed to produce the tantalum alloy via laser additive manufacturing (LAM), vacuum arc remelting (VAR), electron beam melting (EBM), or plasma arc melting (PAM), and (ii) the Mo is present, in the tantalum alloy, in an amount less than its solubility limit in the substantially pure tantalum.
