Usage of ATND method to determination of mechanical properties of AlMg10 alloy with complex additive of SbNiCr
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 3
Abstract
Aluminum alloys with magnesium are commonly used in foundry industry due to lower density and higher corrosion resistance, comparing with silumins. Complicated shapes of produced alloys, differences in wall thickness and operation under changing loads require performing quality control as early as in stage of their preparation (melting). To register crystallization processes and monitor a phenomena arisen in result of the crystallization, are implemented methods based on analysis of temperature change (ATD, DTA). In the paper is present an attempt of usage of the ATND method (Thermal-Voltage-Derivative Analysis) to registration of crystallization process of the investigated alloy. Obtained results concern registration of the crystallization process, strength and fatigue tests of the material, and visual observation of morphology of alloy’s fracture after static tensile test. Performed regression analysis has enabled implementation of changeable values of characteristic points of the ATND method to estimation of mechanical properties of the AlMg10 alloy with SbNiCr additive.
