Preparation of TiN–Ti5Si3 in-situ composites by Selective Laser Melting

Microstructure characteristics and formation mechanisms of in situ WC cemented carbide based hardmetals prepared by Selective Laser Melting

“…Recent research efforts have demonstrated that SLM, due to its flexibility in feedstock and shapes, possesses a promising potential for the net-shape production of complex-shaped, high-performance composites parts. SLM of Al-Si-Mg/SiC [9], Al 50 Ti 40 Si 10 [10], WC/Co [11], TiN/Ti 5 Si 3 [12], TiC/Ti-Al [13], and stainless steel/hydroxyapatite [14] composites have been reported. Nevertheless, due to the complex metallurgical nature of SLM, which involves multiple modes of heat, mass, and momentum transfer induced by localized laser scanning [15], processing problems such as gas entrapment, aggregation of constitution phases, and interfacial microcracks may be produced in SLM-processed composites.…”

Effect of hot isostatic pressing (HIP) on Al composite parts made from laser consolidated Al/Fe2O3 powder mixtures

“…particle and powder interaction) approaches. For example, have studied ex situ SLM of stainless steel and hydroxyapatite composite from their powder mixture, or Gu et al (2009) have prepared in situ TiN-Ti 5 Si 3 SLM composite from the powder mixture of Ti-Si 3 N 4 .…”

Densification, Microstructure, and Wear Property of In Situ Titanium Nitride-Reinforced Titanium Silicide Matrix Composites Prepared by a Novel Selective Laser Melting Process

“…[35] The previous studies on the conventional PM-processed Ti-Si based in situ composites indicate that the ceramic reinforcement is typically in a particle morphology [4][5][6]13] because of a solid-state sintering or a partially melted liquid phase sintering mechanism applied. Differently, the in situ TiN reinforcing phase in SLM-processed TiN/Ti 5 Si 3 composites experiences an interesting change in its morphologies from an irregular polyangular shape to a refined near-round shape and, finally, to a coarsened dendritic shape, on increasing the applied laser energy density (Figures 5(a) through (d)).…”
