【摘要】 本文参照有关标准的具体规定,对钢板拉伸和冷弯试验后的试样进行了广泛的收集、整理,对筛选出的特征明显、代表性强的拉伸试样断口和冷弯试样的实物进行分类和实物图样的制作,使试样的评定有了较形象化的比对参照。通过对文中所列试样实物的介绍和分析,使检、试验人员判定试样的有效性和试验结果的准确性有了直观的依据,为检、试验人员初步判断有无影响试验结果的内外在因素提供了有益的参考,也为进一步进行钢板微观质量检验和生产工艺分析提供了指向,提高了试样质量评定信息的使用价值。更多还原

【Abstract】 With reference to the specific stipulations of relevant standards,the article widely collects and sorts out the data of the steel plate specimens after tensile and cold bending tests,classifies the fractures of the representative tensile specimens with obvious feature and the cold bending specimen selected and plots the drawings of the actual specimens,thus visualized cross references are available for specimen assessment.By describing and analyzing the actual specimens listed in the paper,straight basis is available for the effective specimen judgment and the correct testing results by the testing personnel,useful references are provided not only for the testing personnel to initially judge if there exist any internal and external factors influencing the test results,but also for the guidance of the further micro quality inspection and production process analysis,which increases the service value of the specimen quality assessment information.更多还原
