金属基复合材料夏比冲击试验结果的影响因素与不确定度研究
发布时间：2019-06-07 10:42
【摘要】：本文主要介绍了金属基复合材料夏比冲击试验的两种方法,包括普通冲击试验方法和仪器化冲击试验方法。通过阐述两种方法和优缺点,并从金属基复合材料本身、试样制备加工、冲击试验设备以及试验操作等方面对影响冲击试验结果的因素进行分析讨论,最后对冲击试验结果不确定度的评定方法进行介绍,为夏比冲击试验的应用以及冲击结果的准确获得提供一定的指导作用。
[Abstract]:In this paper, two methods of Charpy impact test for metal matrix composites are introduced, including ordinary impact test method and instrumental impact test method. By expounding the two methods, their advantages and disadvantages, the factors affecting the impact test results are analyzed and discussed from the aspects of metal matrix composites themselves, sample preparation and processing, impact test equipment and test operation. Finally, the evaluation method of uncertainty of impact test results is introduced, which provides certain guidance for the application of Charpy impact test and the accurate acquisition of impact results.
