Transient liquid phase (TLP) bonding could be used for repairing large cracks or worn areas on aerospace components. TLP bonding of IN718 Ni-based alloy and 316LN steel was carried out using BNi-2 Ni-based foil at 1050℃ for different holding time. The formation and evolution of the athermal...

A multiscale approach is presented here to investigate the effect of the ferrite-pearlite microstructure after annealing on the subsequent machining process of steel gears. The case-hardening steel 18CrNiMo7-6 and a cost efficient alternative with reduced Cr and Ni content have been studied....

With the development of 5G communication, more demanding requirements have been specified for copper alloy strips for lead frames. Thin copper alloy strips with high residual stress always warp during the etching process, and they cannot meet the requirements of industry. Therefore, it is...

The dependence of processing route on the microstructure and tensile behavior was analyzed in a V microalloyed Mn-medium steel containing (in mass%) 3.5 Al and 1.2 Si. To obtain four different microstructures, as hot rolled (HR) band was divided in several parts and three of them were submitted...

CoCrNi medium entropy alloy (MEA) has potential applications in cryogenic environment. Its strength and plasticity simultaneously enhanced with decreasing temperatures. However, the poor yield strength ( YS ) at room temperature (RT) ts its widespread application. In this work, the alloying...

The Zn-22Al alloy was processed under different microextrusion conditions to fabricate long and smooth microtubes with good strength and ductility. After direct microextrusion, the outer diameter variation and microstructure evolution of micro-extruded Zn-22Al microtubes under different...

As a free forming additive manufacturing technology for high performance metal parts, laser deposition manufacturing has a broad application prospect in aerospace and other fields. The solidification behavior and microstructure of molten pool determine the mechanical properties of the deposited...

A detailed correlative structural, magnetic and chemical analysis of non-stoichiometric cobalt ferrite micrometric crystals was performed by x-ray magnetic circular dichroism combined with photoemission microscopy, low energy electron microscopy, and atomic force microscopy. The vector...

Niobium silicide coatings were prepared by molten salt on Nb-based multiphase alloys. The nanostructured out-layer ((Nb,Ti)Si 2 or (Nb,Ti,Mo)Si 2 ) and transition layer ((Nb,Ti) 5 Si 3 or (Nb,Ti,Mo) 5 Si 3 ) silicides were formed at the surface of both multiphase alloys. The cyclic oxidation...

The present work takes the benefit of employing a composite approach by reinforcing the pure Mg with bioinert and bioactive ceramic powders for strengthening and reducing their degradation inside the human body to make it a suitable candidate for orthopaedic implants. Hydroxyapatite (HAp) was...
