一、前言冷轧薄带的硬度测量国标“金属小负荷维氏硬度试验方法”。对于薄试样的硬度测量普遍存在着测量值差异大的现象。因为影响示值的因素很多。我们根据实际工作中所能出现的误差,用0.1mm厚的不锈钢带AM350作为研究对象,在样品制备与支撑方法上,试验力的选择、施加方法、保持时间、以及压痕测量方面进行了一系列试验。找出了影响示值误差的因素。 I. Introduction Cold-rolled strip hardness measurement GB “metal small load Vickers hardness test method.” For the thin specimen hardness measurement prevalence of large differences in measured values. Because of the many factors that affect the indication. Based on the error that can occur in actual work, we use the AM350 stainless steel strip with a thickness of 0.1mm as the research object. We conducted a sample preparation and support method, selection of test force, application method, holding time, and indentation measurement Series of experiments Identify the factors that affect the indication error.
