Measurement and Analysis of Hydrogen Distribution in Stress Environment Using Vickers Microhardness Technique

Figure 2

Microhardness increment for each group. The P value is the probability of obtaining a result at least as extreme as the one that was actually observed, given that the null hypothesis is true. When , there is no significant difference in microhardness increment with different periods.
