Characterisation of micro-lattices fabricated by selective laser melting

β-titanium alloys have been touted as the new titanium alloys in biomedical applications due to its lower elastic modulus as compared to the titanium alloys of other phases. In particular, titanium-tantalum has been explored for such applications due to the high biocompatibility of both titanium and...
