在本研究中,在配备电加热炉的万能拉伸试验机上,将拉伸试样加热至600℃保温3小时之后,按照国标GB/T 4338-2006的标准进行高温拉伸试验,测得圆棒的高温抗拉强度为550MPa,屈服强度为475MPa。
In this study, after the tensile specimen was heated to 600℃ for 3 hours on a universal tensile test machine equipped with an electric furnace, the high temperature tensile test was carried out according to GB/T 4338-2006. The high temperature tensile strength and yield strength of the round rod were 550MPa and 475MPa respectively.
