Abstract: This article aimed to illustrate the Transient plane source (TPS) method’s abilities in measuring the local thermal conductivity of metal foams and detecting their in-homogeneities. The Hot Disk TPS method was used to measure the effective thermal conductivity and thermal properties of powder metallurgical (PM)-aluminum (Al) foams, infiltrated aluminum foams, and PM-Zinc foams. The accuracy of the TPS method was then verified in the determination of defects or density in-homogeneities.
