in the present study, the capability of accumulative roll bonding (arb) and subsequent heat-treatment to fabricate solid solution from a multilayered cu/zn/al was investigated. two post-heat treatment (one-step and two-step) routes were proposed. in the first, the arb processed material was heated to 800 c for 5:30 hours and allowed to cool slowly in a furnace (one-step route). in the second (t...

The work presents the results of the studies of Co-Cr-Mo casting alloys used in the production of frame casts of removable dentures, crowns and bridges in dental prosthetics. The studies were performed on four Co-Cr-Mo alloys of different contents of Mo, W and other additives. Electrochemical tests were performed, which aimed at examining the corrosion resistance of the alloys and observing the...

In this work the different contributions to the thermoelectric power (TEP) measurement during the dissolution process of M23C6 carbides in an X45Cr13 stainless steel have been evaluated. Thus, the influences of carbon and chromium contents in solid solution in the austenite, the austenite grain boundaries and the microstructure on the TEP have been determined.

The microstructure plays a crucial role for steel semi-solid forming process, and particularly for the steel thixoforging process, since it determines the thixotropic flow behavior of materials in the semi-solid state. Therefore, it is necessary to well understand the microstructure evolution during high speed heating and forming. Classically, it is investigated on a solid material quenched fro...

High-entropy alloys (HEAs) are novel solid solution strengthening metallic materials, some of which show attractive mechanical properties. This paper aims to reveal the effect of adding small atomic boron on the interstitial solid solution strengthening ability in the laser cladded CoCrFeNiAlxCu0.7Si0.1By (x = 0.3, x = 2.3, and 0.3 ≤ y ≤ 0.6) HEA coatings. The results show that laser rapid soli...

In this paper we study the acoustic properties of a microstructured material such as glass wool or foam. In our model, the solid matrix is governed by linear elasticity and the surrounding fluid obeys Stokes equations. The microstructure is assumed to be periodic at some small scale ε and the viscosity coefficient of the fluid is assumed to be of order ε. We consider the time-harmonic regime fo...

In the present study, the capability of accumulative roll bonding (ARB) and subsequent heat-treatment to fabricate solid solution from a multilayered Cu/Zn/Al was investigated. Two post-heat treatment (one-step and two-step) routes were proposed.

solid solutions of ag-cu were prepared via ball milling process, for about 5-30 h. the cu-20at%ag and cu-3.64at%ag composition were investigated by x-ray diffraction technique. it was realized that the solid solubility level could be increased by increasing the initial solute content in the mixture. in addition, shifts in peak positions of silver and copper were observed with milling time. the ...
