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 ...
Pitzadura bertikalen detekzio eta karakterizazioa termografia infragorria eta laser mugikorra erabiliz
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2020)
In this paper, we introduce a method for detecting and characterising infinite vertical cracks in large samples by means of active infrared thermography and flying spot technique. We scan the sample surface by a focused ...
Termografia infragorri aktiboa materialen azterketarako
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2014)
Active lnfrared Thermography techniques are based in detecting thermal waves previously induced in a material. This thermal waves wi ll travel through the material and carry with them information of the interna! structure ...
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 ...
