Evaluation of Dislocation Densities in Various Microstructures of Additively Manufactured Ti6Al4V (Eli) by the Method of X-ray Diffraction

Muiruri, Amos; Maringa, Maina; Du Preez, Willie (Materials 2020, 13, 5355, 2020-11-26)

Dislocations play a central role in determining strength and flow properties of metals and alloys. Di usionless phase transformation of ! in Ti6Al4V during the Direct Metal Laser Sintering (DMLS) process produces ...
In situ heat treatment in selective laser melted martensitic AISI 420 stainless steels

Krakhmalev, P.; Yadroitsava, I; Fredriksson, G; Yadroitsev, I (Materials and Design, 2015)

The article explores an evolution of a microstructure in AISI 420martensitic stainless steel during selective laser melting. Several upper layers had hardness of 750 HV and contained 21±12 vol.% austenite phase. The final ...
ON THE IMPACT OF DIFFERENT SYSTEM STRATEGIES ON THE MATERIAL PERFORMANCE OF SELECTIVE LASER MELTING- MANUFACTURED TI6AL4V COMPONENTS

Dimitrov, Dimitri; Becker, Thorsten Hermann; Yadroitsev, Igor; Booysen, Gerry (Stellenbosch University Library and Information Service : The South African Journal of Industrial Engineering, 2016)

Selective Laser Melting (SLM) is a powder-based additive manufacturing process that has gained substantial interest in recent years due to its feasibility of producing geometrically- complex metallic components for end-use ...
