摘要：微试样液压爆破法是一种可用于测试核压力容器辐照监督试样的微试样测试技术,该技术借鉴爆破片工作原理,对圆形薄片试样进行液压加压,使薄片鼓胀并爆破,在试验过程中记录载荷-圆薄片中心点位移曲线,通过曲线上的特征载荷以及试样变形关联材料常规拉伸性能。通过比较不同的近似解析法得到了适合于该型微试样试验技术的屈服强度、抗拉强度的计算方法,在上述研究的基础上对核电常用材料国产A508进行了液压爆破试验,得到了材料的强度特性,与常规单轴拉伸数据高度吻合。
The small bursting test is a micro specimen test technique which can be used to test the irradiation surveillance specimens in nuclear reactor pressure vessels.With the same principle of bursting disc,the round thin specimen was hydraulically expanded and burst.Conventional tensile properties were gotten by specific point on load-displacement curves recorded during the test.Different approximate analytical methods were compared in order to get the suitable methods for yield strength and tensile strength calculation.Based on the above study,the small bursting test was performed on domestic nuclear material A508 steel and the strength properties of A508 steel are highly consistent with the conventional tensile data.
