Characterizing Subsurface Rectangular Tilted Heat Sources Using Inductive Thermography
(MDPI, 2020-08-06)
In this study, we characterize the lateral dimension, depth, and inclination of buried tilted rectangular heat sources from time domain temperature data measured at the surface. The heat sources are representative for ...
Vertical Cracks Excited in Lock-in Vibrothermography Experiments: Identification of Open and Inhomogeneous Heat Fluxes
(MDPI, 2022-03-17)
Lock-in vibrothermography has proven to be very useful to characterizing kissing cracks producing ideal, homogeneous, and compact heat sources. Here, we approach real situations by addressing the characterization of ...
Sizing the Depth and Width of Narrow Cracks in Real Parts by Laser-Spot Lock-In Thermography
(MDPI, 2021-09-28)
We present a complete characterization of the width and depth of a very narrow fatigue crack developed in an Al-alloy dog bone plate using laser-spot lock-in thermography. Unlike visible micrographs, which show many surface ...
Peculiar magnetocaloric properties and critical behavior in antiferromagnetic Tb3Ni with complex magnetic structure
(Elsevier, 2019-08-12)
A study on the magnetocaloric properties of a Tb3Ni single crystal (which crystallizes in the orthorhombic Pnma space group) has been undertaken and combined with the study of the character and critical behavior of its ...
Magnetocaloric properties, magnetic interactions and critical behavior in Ho6(Fe,Mn)Bi2 intermetallics
(Elsevier, 2020-02-08)
Four polycrystaline Fe2P-type Ho6(Fe,Mn)Bi2 intermetallic compounds (space group , No. 189, hP9) have been studied using magnetic techniques in order to explore their ability as magnetocaloric materials, and study the ...
Study of the magnetocaloric effect in intermetallics RTX (R = Nd, Gd; T = Sc, Ti ; X = Si, Ge)
(Elsevier, 2019-05-02)
A detailed study of the magnetocaloric properties of six compounds of the intermetallic family RTX (R = Nd, Gd; T = Sc, Ti ; X = Si, Ge) has been undertaken: NdScSi, NdScGe, GdScSi, GdScGe, GdSc(Si0.5Ge0.5) and Gd(Sc0.5Ti0.5)Ge. ...
Critical behavior of the ferromagnetic transition in GdSc(Si,Ge) intermetallic compounds
(Elsevier, 2018-07-26)
A complete study on the critical behavior of the paramagnetic to ferromagnetic transition in intermetallics GdScSi, GdScGe, GdSc(Si0.5Ge0.5) and Gd(Sc0.5Ti0.5)Ge has been carried out by means of magnetic as well as ...
Critical behavior study of magnetic transitions in Dy3Co single crystals
(Elservier, 2018-02-14)
An ac photopyroelectric calorimeter has been used to study the critical behaviour of the magnetic transitions in Dy3Co measuring thermal diffusivity, specific heat and thermal conductivity, at low temperature. There are ...
Thermal Diffusivity Measurement of Laser‐ Deposited AISI H13 Tool Steel and Impact on Cooling Performance of Hot Stamping Tools
(MDPI, 2020-01-20)
Additive manufacturing is a technology that enables the repair and coating of high‐addedvalue
parts. In applications such as hot stamping, the thermal behavior of the material is essential
to ensure the proper operation ...
Measurement of the thermal conductivity of fluids using laser spot lock-in thermography
(Elsevier, 2020-03-25)
In this work, we propose a new method to retrieve the thermal conductivity of fluids, kf, using laser spot
lock-in infrared thermography. The measurement cell consists in two paralepidid blocks separated by a
narrow gap ...
