MODIFICATION INFLUENCE OF MISCHMETAL ON FRACTOGRAPHY FRACTURE OF G17CrMo5-5 CAST STEEL SAMPLES AFTER THE THREE-POINT BENDING TEST
نویسنده
چکیده
J. Kasińska, Faculty of Mechatronics and Machine Design, Kielce University of Technology, Kielce, Poland The article presents the analysis of fracture surfaces after the three-point bending test at a temperature range from + 20 °C to 80 °C. The author shows a beneficial effect of mischmetal on the cracking mechanism and on the character of fractures. It has been shown that the width of the ductile fracture zone under the bottom of the notch and the nature of the cracking mechanism change with decreasing test temperature.
