Estimation of the thermal properties in alloys as an inverse problem

Abstract

This paper provides an efficient numerical method for estimating the thermal conductivity and heat capacity of alloys, as a function of the temperature, starting from temperature measurements (including errors) in heating and cooling processes The proposed procedure is a modification of the known function estimation technique, typical of the inverse problem field, in conjunction with the network simulation method (already checked in many non-lineal problems) as the numerical tool Estimations only require a point of measurement The methodology is applied for determining these thermal properties in alloys within ranges of temperature where allotropic changes take place These changes are characterized by sharp temperature dependencies
