摘要
利用仪器压痕法测试金属的实验设备,开发了一种在结构件无损检测过程中确定布氏硬度的程序。与传统方法不同的是,所提出的程序使用塑性压痕比例参数 a 来确定硬度,该参数等于仪器压痕图在去除该周期测试载荷后的最大周期力 Fmax - 残余压痕深度 hp 坐标中的斜率。根据硬度标准仪器压痕法的一系列测试结果,在 110-650 HBW 的广泛硬度测量值范围内,布氏硬度值与塑性压痕比例参数之间存在线性相关关系。在一些碳素结构钢、耐热钢和高强度钢上分析了使用该程序的特殊性及其局限性。结果表明,使用改进程序获得的布氏硬度测量结果与传统 DSTU ISO 6506-1:2019 方法的结果一致,误差在允许范围内。两者之间的差值不超过 3.9%。本改进程序可用于研究和教育机构的实验室、中央工厂实验室和各下属专业部门,以及在实验室和现场监测运行中关键设备的状况并确定其进一步使用寿命的其他组织。
Improvement of a Procedure for Determining the Brinell Hardness of Structural Steels Based on the Results of Instrumented Indentation
Using the created experimental equipment for testing metals by the method of instrumented indentation, a procedure for determining Brinell hardness during the nondestructive testing of structural elements has been developed. In contrast to the conventional method, the hardness is determined by the proposed procedure using the proportionality parameter of plastic indentation, a, which is equal to the slope of the instrumented indentation diagram in the coordinates maximum force of cycle Fmax – residual indentation depth hp after removing the test load of this cycle. Based on the results of a series of tests by the method of instrumented indentation of hardness standards, a linear correlation dependence was obtained between the Brinell hardness value and the proportionality parameter of plastic indentation in a wide range of measured hardness values of 110–650 HBW. The peculiarities of using this procedure and its limitations are analyzed on a number of structural carbon, heat-resistant, and high-strength steels. It is shown that the Brinell hardness measurement results, obtained by the improved procedure, agree within the permissible error with the results of the conventional DSTU ISO 6506-1:2019 method. The difference between their values does not exceed 3.9%. The presented improved procedure can be used in the laboratories of research and educational institutes, central factory laboratories and specialized divisions of various subordination, and other organizations involved in monitoring the condition of the operating critical equipment and setting its further service life both in the laboratory and in the field.
期刊介绍:
Strength of Materials focuses on the strength of materials and structural components subjected to different types of force and thermal loadings, the limiting strength criteria of structures, and the theory of strength of structures. Consideration is given to actual operating conditions, problems of crack resistance and theories of failure, the theory of oscillations of real mechanical systems, and calculations of the stress-strain state of structural components.
