Journal ArticleDOI
Microscopic examination of the interface region in 6061-Al/SiC composites reinforced with as-received and oxidized SiC particles
TL;DR: In this article, the interface between the aluminum matrix and SiC was characterized by transmission electron microscopy (TEM) and it was shown that no reaction takes place during compocasting between the as-received SiC particles and the molten aluminum.
Journal ArticleDOI
Interfacial reactions and age hardening in AlMgSi metal matrix composites reinforced with SiC particles
TL;DR: In this article, the effects of interfacial reactions on the age hardening response of the materials are also characterized and discussed in detail, and it is shown that it is possible to control the interfacial reaction either to totally suppress age-hardening or to give rise to hardening in the case of a normally non-hardenable matrix alloy.
Journal ArticleDOI
Effects of chemistry, density and size distribution of inclusions on the nucleation of acicular ferrite of CMn steel shielded-metal-arc-welding weldments
TL;DR: In this article, the influence of inclusions on the nucleation of acicular ferrite of six as-deposited CMnTi welds prepared by the shielded-metal-arc-welding process was studied.
Journal ArticleDOI
Multi-Material Direct Ink Writing (DIW) for Complex 3D Metallic Structures with Removable Supports.
TL;DR: A multi-material DIW method is developed to fabricate complex three-dimensional steel structures by creating a removable support printed from a lower melting temperature metal or a ceramic, bringing no significant contamination to the steel structure.
Journal ArticleDOI
Interfacial reactions in Al-Mg (5083)/AI 2 O 3 p composites during fabrication and remelting
TL;DR: In this article, the interface reactions between a-Al2O3 particles and 5083 Al-Mg alloys during fabrication by compocasting and subsequent remelting at 800 °C for 30 minutes have been studied using analytical transmission electron microscopy (TEM) and scanning electron microscope (SEM).
