The Fe-Ni-Pb-B alloy nanoparticles was prepared by a solid-solid chemical reaction of ferric trichloride, nickel chloride, lead acetate, and potassium borohydride powders at room temperature. The research results of the ICP and thermal analysis indicate that the resultants are composed of iron, nickel, lead, boron, and PVP, and the component of the alloy is connected with the mole ratio of pota...

The effect of the die materials on the fracture strength of CAD/CAM monolithic ceramic crowns was studied in this research. Three different types of die materials (dentin, Ni-Cr alloy, epoxy resin) were prepared. The monolithic crowns were fabricated using a CAD/CAM System; CEREC 4. The CAD/CAM crowns were cemented to dies using a resin cement. The specimens were tested under compressive load a...

PURPOSE The porcelain fused to gold has been widely used as a restoration both with the natural esthetics of the porcelain and durability and marginal fit of metal casting. However, recently, due to the continuous rise in the price of gold, an interest towards materials to replace gold alloy is getting higher. This study compared the bond strength of porcelain to millingable palladium-silver (P...

Functional plating such as alloys or dispersion coatings have been widely used in metal finishing industry. In general, dispersion coatings are deposited from plating baths containing suspended particles such as metal oxides, carbides, metals or organic materials,(l-3) Codeposited particles in the dispersion coatings have the remarkable influence on the properties of the deposits depending on t...

The growth and interdiffusion of Ti and Ni on a Mo( 110) surface have been studied by Auger electron spectroscopy (AES), low energy electron diffraction (LEED) and temperature programmed desorption spectroscopy (TPD). Ti grows layer-by-layer upon deposition on MO{ 110) at 115 K, whereas annealing multifaye~ of Ti to 900 K causes formation of Ti three-dimensional clusters. Submonolayer Ti on Mo(...

This research aims to evaluate the relationship between chemical composition of low alloy steel, temperature, and mechanical properties steel using Exploratory Data Analysis (EDA) techniques. The dataset is visualized a correlation heat map, which shows its treatment temperature. Based on results an evaluation carried out scatterplots. visualization with scatterplots show trend line indicating ...

In this study, the microstructure of thermal effective martensitic phase transformation observed in Fe-30wt.%Ni-2.6wt.%Mo-Xwt.%Co (X = 0.8, 1.8) alloy was investigated morphologically and crystallographically by using Scanning Electron Microscopy (SEM) Transmission (TEM). SEM studies, it that morphology martensite changed from lath lenticular structure to massive with addition Co alloy. this, n...
