Rapid fabrication of Al-based bulk-form nanocomposites with novel reinforcement and enhanced performance by selective laser melting
TL;DR: In this paper, a ring-structured nanoscale TiC reinforcement with a regular distribution was tailored along the grain boundaries of the matrix by selective laser melting (SLM) to produce TiC/AlSi10-Mg nanocomposite parts.

Selective laser melting of in-situ Al4SiC4 + SiC hybrid reinforced Al matrix composites: Influence of starting SiC particle size
TL;DR: In this article, the influence of starting SiC particle size on the constitutional phases, microstructural features, and mechanical properties of the SLM-processed composite parts was studied.

Laser cladding of MMC coatings on aluminium substrate: influence of composition and microstructure on mechanical properties
TL;DR: In this article, the influence of the composition and the microstructure of laser cladded metal matrix composite (MMC) coatings on their mechanical properties (namely hardness and adhesive wear resistance) was investigated.
Journal ArticleDOI
Microstructure and wear studies of laser clad Al-Si/SiC(p) composite coatings
TL;DR: In this article, the influence of the processing parameters on the microstructure and abrasive wear resistance of a composite material consisting of an Al-Si matrix reinforced with SiC particles were produced by laser cladding on UNS A03560 cast Al-alloy substrates from mixtures of powders of Al 12 wt.% Si alloy and SiC.

Stable and metastable phase equilibria in the chemical interaction between aluminium and silicon carbide
TL;DR: In this paper, an experimental investigation was carried out on the Al-C-Si ternary system under atmospheric pressure and at temperatures up to 1900 K. From the results obtained, a thermodynamic model based on stable and metastable phase equilibria was set up in order to provide a general description of the chemical interaction between aluminium and SiC.

Reactive wetting of liquid metals on ceramic substrates
X.B. Zhou,J.T.M. de Hosson +1 more
TL;DR: In this article, the volume change of ceramic substrates during reaction plays a key role in the effect of chemical reaction on wetting, and it is shown that if the volume of ceramic substrate increases after reaction, the wettability is improved by the chemical reaction.
Journal ArticleDOI
Prediction of Si contents to suppress the formation of Al4C3 in the SiCp/Al composite
TL;DR: In this article, the authors used SEM, DSC, AES, and XRD combined techniques in elucidating detailed interfacial phenomena in the SiC p /Al composite and showed that there exists a transition temperature at which a sudden increase in equilibrium Si contents required to prevent Al 4 C 3 formation occurs.

Particulate-TiC-hardened steel surfaces by laser melt injection
J.D. Ayers,T.R. Tucker +1 more
TL;DR: In this paper, the surface layer consists of the hard relatively coarse (a cross section of the order of 100 μm) injected particles in a soft matrix, which contribute to the hardening of the surface.
