摘要

本文的目的是研究0.09807 N ~ 0.9807 N的外加载荷对6082热处理铝合金显微硬度测量值的影响。采用Meyer 's指数n、PSR法和方差分析(ANOVA)评价外加载荷对显微硬度测量值的影响。载荷对显微硬度测量值的影响具有统计学意义，载荷与显微硬度之间的关系表现为中度逆ISE。随着固溶处理温度的升高，YS/UTS比、Meyer指数n、实测硬度和“真硬度”均增大。另一方面，它对合金塑性性能的影响是不明确的。

INDENTATION SIZE EFFECT OF HEAT TREATED ALUMINUM ALLOY

The aim of the submitted work is to study the influence of applied loads ranging from 0.09807 N to 0.9807 N on measured values of micro-hardness of heat treated aluminum alloy 6082. The influence of applied load on a measured value of micro-hardness was evaluated by Meyer’s index n, PSR method and by Analysis of Variance (ANOVA). The influence of the load on the measured value of micro-hardness is statistically significant and the relationship between the applied load and micro-hardness manifests the moderate reverse ISE. As the temperature of the solution treatment rises, the YS/UTS ratio and also Meyer’s index n, measured and “true hardness“ increase. On the other hand, its effect on the plastic properties of the alloy is ambiguous.
