Cture of material exhibits ferritic earlitic matrix. Certainly one of this two plates has microstructure of material exhibits aaferritic earlitic matrix. Among this two plates has been heated in the oven at temperature of about 950 C for min and, subsequently, been heated inside the oven at aatemperature of about 950 for 44min and, subsequently, itit has been JX401 supplier quenched in water to get martensitic microstructure. To avoid the influence has been quenched in water to obtain aamartensitic microstructure. To prevent the influence from the absorptivity and emissivity within the transmission measurement, thin layer of black with the absorptivity and emissivity within the transmission measurement, aathin layer of black 3MB-PP1 Polo-like Kinase (PLK) higher temperature resistant paint has been applied on both surfaces for both specimens. higher temperature resistant paint has been applied on each surfaces for each specimens.two.two. Thermographic Setup and Information Analysis two.2. Thermographic Setup and Data Analysis Two distinct thermographic set-ups happen to be applied: the first 1 in transmission Two distinct thermographic set-ups happen to be utilised: the first 1 in transmission mode, for the application of Parker’s system, the other one in reflection mode for the mode, for the application of Parker’s strategy, the other 1 in reflection mode for the application Bison’s. For transmission measurements, Figure 1a, one flash lamp working with six kJ application Bison’s. For transmission measurements, Figure 1a, one particular flash lamp applying 6electrical energy (Hensel Studio Technik, EH Pro 6000) irradiated the back surface of kJ electrical power (Hensel Studio Technik, EH Pro 6000) irradiated the back surface of specimen (distance 50 mm, angle 00for aatime of two ms. The flash has been aligned to specimen (distance 50 mm, angle) for time of two ms. The flash has been aligned to create an homogeneous heating and get greater power density. Thermal signal around the create an homogeneous heating and receive greater power density. Thermal signal on the front surface has been recorded by MWIR-camera (Flir X6540 sc) with aaNEDT of 25 mK, front surface has been recorded by MWIR-camera (Flir X6540 sc) with NEDT of 25 mK, for 33ssusing aa frame rate of 530 Hz in addition to a subframe of 188 20 pxl2 . .The camera equipped for applying frame rate of 530 Hz and also a subframe of 188 320 pxl2 The camera equipped with aa 50 mm lens, 480 mm in the specimen has been placed with a spatial resolution 50 mm lens, 480 mm from the specimen has been placed using a spatial resolution of with 0.18 mm/pxl. of 0.18 mm/pxl.Figure 1. Experimental set up in (a) transmission mode, and (b) reflection mode. Scheme with the Figure 1. Experimental setup in (a) transmission mode, and (b) reflection mode. Scheme of the inspected locations for (c) transmission and (d) reflection measurements (lengths are in mm). inspected locations for (c) transmission and (d) reflection measurements (lengths are in mm).For reflection configuration measurements, Figure 1b, Ytterbium pulsed fiber laser For reflection configuration measurements, Figure 1b, Ytterbium pulsed fiber laser (YLP-V211mJ series) with nominal power of 50 W with circular spot diameter of 44mm (YLP-V2 mJ series) with nominal energy of 50 W with circular spot diameter of mm has been made use of with excitation duration of six ms. The laser has been placed frontally to has been applied with excitation duration of 6 ms. The laser has been placed frontally for the surface to avoid distortion of circular and gaussian distribution of power. Exactly the same the surface to a.
