Cture of material exhibits ferritic earlitic matrix. Certainly one of this two plates has microstructure of material exhibits aaferritic earlitic matrix. One of this two plates has been heated inside 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 receive martensitic microstructure. To prevent the influence has been quenched in water to receive aamartensitic microstructure. To prevent the influence with the absorptivity and emissivity inside the transmission measurement, thin layer of black of the absorptivity and emissivity within the transmission measurement, aathin layer of black higher temperature resistant paint has been applied on each surfaces for each specimens. higher temperature resistant paint has been applied on each surfaces for both specimens.two.2. Thermographic Setup and Data Evaluation two.2. Thermographic Setup and Information Evaluation Two distinctive thermographic set-ups have been applied: the initial a single in transmission Two diverse thermographic set-ups have been utilized: the very first one in transmission mode, for the application of Parker’s approach, the other one in reflection mode for the mode, for the application of Parker’s approach, the other one particular in reflection mode for the application Bison’s. For transmission measurements, Figure 1a, one flash lamp applying six kJ application Bison’s. For transmission measurements, Figure 1a, a single flash lamp using Aminopurvalanol A Epigenetics 6electrical power (Hensel Studio Technik, EH Pro 6000) irradiated the back surface of kJ electrical energy (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 create an homogeneous heating and acquire greater power density. Thermal signal around the produce an homogeneous heating and acquire greater 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 rate of 530 Hz as well as a subframe of 188 20 pxl2 . .The camera equipped for using frame rate 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 Solvent violet 9 Technical Information 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 the Figure 1. Experimental set up in (a) transmission mode, and (b) reflection mode. Scheme of your inspected places for (c) transmission and (d) reflection measurements (lengths are in mm). inspected regions 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 applied with excitation duration of six ms. The laser has been placed frontally to has been used 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. The identical the surface to a.
