s The purpose of this study was carried out by the embryotoxicity risk assessment of the dental alloys containing indium. We produced Ag-In alloy, Ag-Pd-Au-Cu alloy and gold alloy for porcelain bonding. For the extraction of these alloy components into the ES-D3 cell culture medium, each alloy was reduced to a powder using a diamond point and sterilized after rinsing. In order to facilitate the...
Electrochemical impedance spectroscopy was used as an in situ technique to determine the average particle size of metal hydride electrodes. Using this, the pulverization of bare and cobalt-encapsulated LaNi Sn alloy was studied as a function of charge–dis4.27 0.24 charge cycles. In the case of bare alloy, pulverization causes an exponential decay in particle size with cycling. Cobalt-encapsulat...
The galvanic corrosion behavior of Alloy 690 coupled with magnetite has been investigated in an alkaline solution at 30 °C and 60 °C using a potentiodynamic polarization method and a zero resistance ammeter. The positive current values were recorded in the galvanic couple and the corrosion potential of Alloy 690 was relatively lower. These results indicate that Alloy 690 behaves as the anode of...
Bu çalışmada Al7075–T6 sac malzemesinin tavlama parametrelerine bağlı olarak V bükme ile şekillendirilebilirliği ve geri esneme davranışı deneysel araştırılmıştır. Tavlama işlemleri, farklı sıcaklıklarında (100, 200, 300 400 °C) sıcaklığında tutma sürelerinde (6, 30 60dk.) uygulanmıştır. Tavlanan numunelerin 15, 30, 45, 60 75 derece açılı kalıplarında sabit deformasyon hızında bükülerek incelen...
We present Prioni, a tool that integrates model checking and theorem proving for relational reasoning. Prioni takes as input formulas written in Alloy, a declarative language based on relations. Prioni uses the Alloy Analyzer to check the validity of Alloy formulas for a given scope that bounds the universe of discourse. The Alloy Analyzer can refute a formula if a counterexample exists within ...
in the present study, mechanical properties and low cycle fatigue behavior of a solid-solutionized aa6061 aluminum alloy produced by equal channel angular pressing (ecap) process were investigated. the grain refinement after two passes of ecap significantly increased the yield stress and ultimate tensile stress and decreased the ductility of the alloy. however, the improvement of low cycle fati...
alloy steel, which is versatile in such qualities as grade, property and application, can play an important role in the technical and economic development of the country. the present consumption of the key industrial sector to this strategic material, specified basically as semi- finished products exceeds 100,000 tons per year. however, a rough estimation of the true potential needs, does clear...
in this study, cu50-ni50 alloy were synthesized by mechanical alloying. the alloy was then reinforced by dispersion of multiwalled carbon nanotubes using a planetary high energy ball mill. x-ray diffraction, scanning electron microscopy and vibrating sample magnetometer were used to evaluate the effects of cnt addition on the characteristics of the nanocomposites. xrd results of cu-ni sample sh...
