Effect of different total test force holding time on Rockwell hardness test results of aluminum alloy
摘 要
在总试验力保持时间分别为2,3,5,6,9 s时,对几种牌号的铝合金材料进行洛氏硬度测试,统计分析了试验数据。结果表明:在不同总试验力保持时间条件下,铝合金材料的洛氏硬度为0.3~1.0 HRB,基本呈下降趋势。结果可为生产现场铝合金状态检查时的数据处理提供可靠依据。
Abstract
The Rockwell hardness test of several brands of aluminum alloy materials was carried out when the total test force holding time was 2, 3, 5, 6, 9 s, and the test data were statistically analyzed. The results show that under the condition of different total test force holding time, the Rockwell hardness of aluminum alloy material was 0. 3-1. 0 HRB, which was basically decreasing. The results could provide a reliable basis for the data processing of aluminum alloy condition inspection in the production site.
