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 ...
Metal Additive Manufacturing Of Titanium Aluminides From Blended Elemental Powder

Zenani, Asavela (Central University of Technology, 2020-05)

Titanium aluminide is considered a key material for high performance gas turbines for aircraft engines, manufacturing of engine valves and a variety of automotive applications. This is due to the attractive high oxidation ...
Microstructure and mechanical properties of Ti6Al4V (ELI) parts produced by DMLS

MOLETSANE, MORAKANE GLORIA (Bloemfontein: Central University of Technology, Free State, 2016)

Direct Metal Laser Sintering (DMLS) is an Additive Manufacturing (AM) technology where powder is melted by the laser beam track-by-track, layer-by layer to produce complex components. The advantage of DMLS is manufacturing ...
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 ...
Residual stress of Ti6Al4V (ELI) parts manufactured by direct metal laser sintering

van Zyl, Ian (Bloemfontein: Central University of Technology, Free State, 2016)

This study focuses on the residual stress in Ti6Al4V (ELI) parts manufactured by direct metal laser sintering (DMLS). During DMLS a laser beam scans over the powder layer thus melting the powder and previous layer. ...
