Abstract:

The numerical simulation model of rapid solidification splat-quenching CuCr25 alloys was built in this paper. The vacuum chamber, cooling cooper plate and sample were taken into account as a holistic heat system. Based on the heat transfer theory and liquid solidification theory, the heat transfer during the rapids solidification process of CuCr25 flakes prepared by splat-quenching can be approximately modeled by one-dimensional heat conduction equation, so that the temperature distribution and the cooling rate of the flake can be determined by the integration of this equation.

Abstract:

PtCo hard magnets have specialized applications owing to their relatively high coercivity combined with corrosion resistance and ductility. Increased intrinsic coercivity has been recently obtained by rapid solidification processing of PtCo alloys containing boron. After rapid solidification by double anvil splat quenching and subsequent annealing for 30 minutes at 650°C, an alloy with composition Pt42Co45B13 (at.%) exhibited intrinsic coercivity up to 14kOe. This represents a significant improvement compared to the average coercivities in conventional binary PtCo alloys of 5 to 8 kOe.Rapidly

Abstract:

Rapid solidification of Ti rare earth alloys can produce a fine rare earth oxide dispersion. A stable distribution of rare earth oxides in a hexagonal Ti matrix has been shown to increase the flow stress at both room and elevated temperatures. Previous studies have investigated the precipitation phenomena in Ti-erbium Ti-Ianthanum, and Ti-Al-gadolinium alloys. The present research addresses oxide precipitation in a Ti-cerium alloy as a result of rapid solidification processing.Samples of Ti-4 wt% Ce were rapidly solidified by splat quenching 300 mg droplets, after free fall in a 100 m drop tub

Abstract:

A primary goal of RSP has been to enhance the post-solidification age-hardening behavior of alloys via the extension of solute solubility of their terminal solid solutions. In the case of Al-Be, it was a matter of creating supersaturation of Be in Al since Be solubility is so very low at equilibrium. This approach failed and melt-quenching produced a variety of fine-scale, two-phase microstructures in splats and ribbons. Included were remarkably uniform dispersions of tiny, spherical, incoherent Be particles appearing over a range of compositions spanning the eutectic (Ce=2.5 at% Be) and beyon

Abstract:

The present study focused on examining the composition, structure, and mechanical properties of an Al4CoCrCuFeNi multicomponent high-entropy alloy. Two states of the alloy, namely as-cast and melt-quenched, were investigated. The composition of the alloy was determined based on established criteria found in literature, which consider factors such as entropy, enthalpy of mixing, valence electron concentration, and atomic size difference of the components. To synthesize the alloy films, a splat-quenching technique was employed, where the films were rapidly cooled from the molten state. The estim

Abstract:

The article investigates the structure and physical properties of the multicomponent high-entropy alloy CoCr0.8Cu0.64FeNi in the cast and quenched state. The composition of the alloy under study is analyzed using the criteria available in the literature for predicting the phase composition of high-entropy alloys. These parameters are based on calculations of the entropy and enthalpy of mixing and also include the concentration of valence electrons, the thermodynamic parameter Ω, which takes into account the melting point, entropy of mixing, and enthalpy of mixing.

Abstract:

Oxygen impurities play a crucial role in the glass-forming ability and crystallisation behaviour of metallic glasses. In the present work, single laser tracks were produced on Zr59.3-xCu28.8 Al10.4Nb1.5Ox substrates (x = 0.3, 1.3) to study the redistribution of oxygen in the melt pool under laser melting, which provides the basis for laser powder bed fusion additive manufacturing. Since such substrates are commercially not available, they were fabricated by arc melting and splat quenching. X-ray diffraction revealed that the substrate with 0.3 at.% oxygen was X-ray amorphous, while the substra

Abstract:

In the last quarter of a century, modification of the near-surface region of materials has become of major technological importance. The principal surface modification technique utilized in integrated circuit technology is ion implantation, a technique which has more recently been applied in the metal-processing industry as well. The very high doses required for applications such as increasing the hardness of steel or forming buried oxide layers in silicon have pushed ion implantation to its limits.

After annealing at 800 °C, all powders contained mainly a phase of C-type bixbyite structure. After laser melting, all samples were quenched in a single-phase monoclinic B-type structure.

Abstract:

Rare-earth intermetallic compounds with high Fe concentrations and adopting the ThMn12–type and Th2Zn17-type structures have attracted considerable attention in the field of permanent magnets. A large number of experimental studies has been done on these compounds, which are usually measured on alloys structurally characterized only by powder X-ray diffraction (XRD). However, the materials are often multiphasic and their quenched or annealed microstructures evidence homogenization ranges, second phases (resulting from segregation) and on-going phase transformations that may not be easily detec

With an aim of obtaining aluminum P/M materials strengthened by dispersion of transition metal compounds and solid solution of Mg , Al -2 mass % Co and Al -5 mass % Co alloys with varied Mg additions of 0, 1 and 5 mass% were prepared by rapid solidification techniques. Rapidly solidified flakes were produced by argon gas atomization and subsequent splat quenching on a water-cooled copper roll. The flakes were consolidated to the P/M (Powder metallurgy process is named as P/M) materials by hot extrusion after vacuum degassing.
