Powder bed binder jet printing (BJP) is an additive manufacturing method in which powder is deposited layer-by-layer and selectively joined in each layer with binder. The data presented here relates to the characterization of the as-received feedstock powder, BJP processing parameters, sample preparation and sintering profile ("Effect of solutionizing and aging on the microstructure and mechani...

CoHErrelation between weldability and improvement in properties is a key issue in materials science research. The objective of this work is to optimize the process parameters viz., aging temperature, aging time, solutionizing time, to enhance the hardness of Al6061 alloy. Hence, the present paper deals with hardness study of Tungsten Inert Gas welded 6061 aluminium alloy after age hardening und...

This work studied the precipitation characteristics of AlSi10Mg0.3Mn alloy produced by high-pressure vacuum die-casting in T5 and T6 conditions using transmission electron microscopy, differential scanning calorimetry both electrical conductivity microhardness measurements. Two different tempers were used, involving partial solutionizing at 460 °C for 1 h full 500 h, designated as T6P T6F, resp...

The post-processing treatment response of a Y2O3 oxide-dispersion-strengthened (ODS) and γ/γ′-strengthened Ni–8Cr–5.5Al–1Ti (wt.%) model alloy, produced by laser powder bed fusion (L-PBF) is studied. solutionizing at 1260 °C induces significant recrystallization the initial elongated grain microstructure, characteristic L-PBF processing. Grain-boundary pinning dispersoids affects efficiency, le...

In this paper, we studied the oxidation behavior in AA7075 containing TiB2 nanoparticles. The results indicate that nanoparticles play distinctive roles during coupled processes. At a lower temperature, ruptures Al2O3 film and refine microstructure morphology. Above solutionizing point, Zn proceeds deeply into matrix, partially block diffusion path to increase gradient. TiB2-regulated is respon...

Phase transformations and the resulting microstructural evolution of near-Ti2AlNb and Ti-12Al38Nb O 1 bcc orthorhombic alloys were investigated. For the near-Ti2AlNb alloys, the processing temperatures were below the bcc transus, while, for Ti-12Al-38Nb, the processing temperature was supertransus. Phase evolution studies showed that these alloys contain several constituent phases, namely, bcc,...
