In situ synthesis of TiC-NiCr cermets during selective laser melting (SLM) was investigated. Powder mixture consisting Ti, C and Ni80Cr20 solid solution was prepared by milling process to attain Aerospace Free Full-Text Selective Laser Melting of Selective laser melting (SLM) is a near-net-shape time- and cost-effective manufacturing technique, which can create strong and efficient components with potential applications in the aerospace industry. To meet the requirements of the growing aerospace industrial demands, lighter materials with enhanced mechanical properties are of the utmost need.

Aluminum with dispersed nanoparticles by laser additive

Sep 11, 2019 · The surface-coated and uniformly dispersed TiC nanoparticles inside the AMNC powders can enhance TiC particles, was repeated twice before of the preheating and laser selective melting. The On the influence of TiB2, TiC, and TiN hard particles on Apr 29, 2020 · Löschau et al. investigated the laser dispersing behavior of TiC particles on non-heat-treated carbon and tool steels. On 90MnV8 substrates, the authors observed dispersed primary TiC particles in different arrangements and concentrations. Depending on the interaction time and temperature, the dispersed particles are angular and/or rounded. Selective Laser Melting Additive Manufacturing of Hard Selective laser melting (SLM) additive manufacturing (AM) of hard-to-process W-based parts with the addition of 2.5wt.% TiC was performed using a new metallurgical process- system, the nano-TiC particles were dispersed and mixed uni-formly during ball milling treatment. After milling process, the

Selective Laser Melting (SLM). Two categories of nanopowder, i.e., ball-milled TiC/Ti nano- force between neighboring particles may result in the microstructural inhomogeneity, and even the disappear- ultrane TiC nanoparticles were dispersed uniformly around Ti particles surface after the mechanical mixing process (Figure 2(c)). In Selective Laser Melting of Graphene Reinforced Inconel 718 The microstructures of the TiC reinforcing phase experienced a successive change as laser energy input per unit length increased:Relatively coarsened poly-angular particles (80 kJ/m) - surface Selective Laser Melting to Manufacture In Situ Metal They have found that TiC particles form in situ within the 316L stainless steel matrix through a laserinduced reaction via a nucleationgrowth mechanism from the melt (Figure 16). This resulted in the dispersion of nano TiC particles within the 316L matrix with a maximum density of 98.88%.

Selective Laser Melting to Manufacture In Situ Metal

They have found that TiC particles form in situ within the 316L stainless steel matrix through a laserinduced reaction via a nucleationgrowth mechanism from the melt (Figure 16). This resulted in the dispersion of nano TiC particles within the 316L matrix with a maximum density of 98.88%. Selective laser melting additive manufacturing of TiC parameter laser energy density (g), which was dened by:g ¼ 4P vpd2; ð1Þ was used to estimate the laser energy input to the powder layer being processed. Thus four different laser energy densities g of 3, 3.9, 4.7, 5.1 kJ/mm3 were determined to Q. Jia et al.:Selective laser melting of TiC/Inconel 718 bulk-form nanocomposites Selective laser melting of 316L stainless steel:Influence Dec 01, 2019 · 1. Introduction. Among the different additive manufacturing (AM) processes, laser based powder bed fusion (LPBF) or commonly known as selective laser melting (SLM) is the most preferred AM process for the fabrication of metallic components with complex geometries and superior properties [1,2] because of its ability to process wide spectrum of materials [, , , , ].

Selective laser melting of TiC/Ti bulk nanocomposites

Selective laser melting of TiC/Ti bulk nanocomposites:Inuence and the homogeneously dispersed TiC reinforcement had a nanoscale lamellar structure that was completely dierent to the starting nanoparticle morphology. The 98.3% dense TiC/Ti nano- tion layers between particles Stainless Steel Fabricated by Selective Laser MeltingStainless Steel Fabricated by Selective Laser Melting Shahir Mohd Yusuf 1, Yifei Chen 1 studied the SLM of TiC-reinforced 316L SS matrix nanocomposites and found that the addition of ne TiC particles remarkably improved the post-processing due to the formation of homogenously dispersed TiB2 particles forming nanoscaled Surface & Coatings TechnologySelective Laser Melting of in-situ TiC/Ti 5Si 3 composites with novel reinforcement architecture and elevated performance Dongdong Gua,b,, Yves-Christian Hagedorna, Wilhelm Meinersa, Konrad Wissenbacha, Reinhart Poprawea a Fraunhofer Institute for Laser Technology ILT/Chair for Laser Technology LLT, RWTH Aachen, Steinbachstraße 15, D-52074 Aachen, Germany

Tribological Behavior of TiC Particles Reinforced 316Lss

In order to improve the abrasion performance of 316Lss, make full use of its advantages and broaden its application fields, the tribological behavior of the TiC particles reinforced 316Lss compositeswhich were manufactured by selective laser melting (SLM)were investigated. In this study, GCr15 bearing steel was selected as the friction material and experiments on the sliding friction and Selective laser melting of dispersed TiC particles Selective laser melting of dispersed TiC particles strengthened 316L stainless steel 316L austenitic stainless steel has a wide range of industrial applications. However, one of the major drawbacks is its low yield strength (170300 MPa in annealed state).
