Effect of Built Geometry on the Microstructure and Strength Characteristics of the Ti–6Al–4V Alloy Prepared by the Selective Laser Melting

Microstructure and tensile properties of additive manufactured Ti-6Al-4V with refined prior-β grain structure obtained by rapid heat treatment

“…The average prior-β grain size achieved af ter RHT is not only significantly smaller than the original as-built status but also considerably smaller than that reported in a number of studies where the microstructure of L-PBF Ti-6Al-4V (printed on similar EOS platforms) wa s investigated (Ta ble 3) [33][34][35][36][37].…”

Analysis of the Structure and Mechanical Properties in Medical Alloys Based on Titanium and Cobalt Manufactured by Selective Laser Melting

“…The {1012} ⟨1011⟩ hexagonal martensite tensile twins were observed in the microstructure of the as-build alloy [1]. It has been found that the hardness and elastic modulus (EIT) measured by the nanoindentation method depend on the sample built geometry [2]. The occurrence of a martensitic transformation in SLM samples was detected.…”
