AbstractThe influence of strontium on the silicon modification and aluminium-copper eutectic microstructures in 319 aluminium alloy was examined. The levels considered were between 8 96 ppm. purpose this study is: (i) to observe effects degree alloy, (ii) determine level area fraction copper phases. determined using American Foundrymen's Society (AFS) specification. fractions phases examined scanning electron microscopy (SEM) quantitative image analysis (IA). This investigation showed that a...
The Effect of Major Alloying Elements on the Size Secondary Dendrite Arm Spacing in As-Cast Al-Si-Cu Alloys A comprehensive understanding melt quality is paramount importance for control and prediction actual casting characteristics. Among many phenomenon that occur during solidification castings, there are four structure consequently mechanical properties: chemical composition, liquid metal treatment, cooling rate temperature gradient. alloy composition most important among them. This paper...
There is a long process to transform bauxite, critical raw material, into substance with the required properties of cast aluminum alloys for use in electro automotive parts. Thanks its unique properties, has become material choice clean technology manufacturers applications such as industry, renewable energy, batteries, electrical systems, resource-saving packaging, energy efficient buildings and mobility. Restructuring economy, oil crisis, air pollution global warming are some factors that...
The cooling curve analysis (CCA) has been used extensively in the metal casting industry, usually to predict alloy compositio n and microstructure constituents. use of CCA can be expanded other areas solidification if zero curves properly calculated. In this paper Newtonian Fourier techniques determination are described. These were developed calculate latent heat determine correlations between solid fraction temperature/time for Al-7 wt%Si alloy. importance changes capacity density liquid...

The purpose of this paper is to develop a mathematical equation, which will be able accurately predict the liquidus temperature various aluminum and magnesium cast alloys on basis their known chemical compositions. An accurate knowledge permits researcher variety physical parameters pertaining given alloy. analytical expressions presented in are based “method equivalency.” According concept, influence any alloying element an and/or alloy can translated into equivalent reference element....
The aim of this work is to give an overview existing methods and introduce three new for the determination Dendrite Coherency Point (DCP) AlSi10Mg alloys, as well compare acquired values DCP based on a thermal analysis cooling curves working with only one thermocouple. Additionally, impact alloying contaminant elements will be also studied. first two proposed employ higher order derivatives curves. was determined crossing point second third derivative plotted versus time (method 1) or that...
Latent heat is commonly measured using Differential Thermal Analysis (DTA) or Scanning Calorimetry (DSC) calculated software packages (Thermo-Calc). In this study, the DSC method was used to comprehensively evaluate accuracy of latent for a specific range cast AlSiCu alloys, considering their solidification under different cooling conditions. The tests involved varying concentrations two crucial alloying elements: wSi (5, 7, and 9%) wCu (1, 2, 4%). All selected alloys were analyzed three...
La modelización de los procesos fundición ha sido un tópico interés durante las últimas décadas, y la cantidad programas simulación existentes en el mercado es buen indicador del industria este campo. mayoría datos empleados estos se basan diagramas fase binarios, ternarios o incluso superiores. Desafortunadamente, excepto para ajuste no lo suficiente bueno. Teniendo cuenta que sistemas binarios aluminio están bien definidos intentado convertir multi-componentes pseudo binario sistema Al-Xi...
Abstract A comprehensive understanding of the solidification process is paramount importance for control and prediction actual casting characteristics. The present work presents potential cooling curve analysis to characterize path a cast hypoeutectic series Al–Si–Cu alloys. aim this was examine how variation in chemical composition Si (from 5–9 wt.%) Cu 1–4 may affect characteristic temperatures, their corresponding solid fraction, thermal freezing ranges investigated All parameters that...
