Cture of material exhibits ferritic earlitic matrix. One of this two plates has microstructure of material exhibits aaferritic earlitic matrix. One of 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 quenched in water to obtain martensitic microstructure. To prevent the influence has been quenched in water to receive aamartensitic microstructure. To prevent the influence of the absorptivity and emissivity in the transmission measurement, thin layer of black from the absorptivity and emissivity in the transmission measurement, aathin layer of black higher temperature resistant paint has been applied on each surfaces for each specimens. high temperature resistant paint has been applied on both surfaces for both specimens.two.2. Thermographic Setup and Data Analysis two.2. Thermographic Setup and Data Analysis Two unique thermographic set-ups have been applied: the initial 1 in transmission Two distinctive thermographic set-ups have been made use of: the first a single in transmission mode, for the application of Parker’s method, the other 1 in reflection mode for the mode, for the application of Parker’s method, the other 1 in reflection mode for the application Bison’s. For transmission measurements, Figure 1a, 1 flash lamp applying 6 kJ application Bison’s. For transmission measurements, Figure 1a, one particular flash lamp employing 6electrical power (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 2 ms. The flash has been aligned to specimen (distance 50 mm, angle) for time of 2 ms. The flash has been aligned to make an homogeneous PF-06454589 Cancer heating and get larger energy density. Thermal signal on the generate an homogeneous heating and get higher power density. Thermal signal around 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 price of 530 Hz and also a subframe of 188 20 pxl2 . .The camera equipped for making use of frame price of 530 Hz plus a subframe of 188 320 pxl2 The camera equipped with aa 50 mm lens, 480 mm in the specimen has been placed having a spatial resolution 50 mm lens, 480 mm from the specimen has been placed with 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 of your Figure 1. Experimental set up in (a) transmission mode, and (b) reflection mode. Scheme of the inspected locations for (c) transmission and (d) reflection JPH203 Technical Information measurements (lengths are in mm). inspected places 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 energy of 50 W with circular spot diameter of 44mm (YLP-V2 mJ series) with nominal power of 50 W with circular spot diameter of mm has been made use of with excitation duration of 6 ms. The laser has been placed frontally to has been used with excitation duration of six ms. The laser has been placed frontally towards the surface to avoid distortion of circular and gaussian distribution of power. Exactly the same the surface to a.
