Correction to: Microstructural and Phase Evolution Behavior of Compound Layers of Controlled Gaseous Nitrided AISI 1015 Steel

In the original online version of this article there were typographical errors in point 2 of the Conclusions section.Following is the corrected text:(2) The nitride compound existed in two phases, the e phase and the c¢ phase.In the initial nitriding process, the c¢ phase was 5.8 pct due to a high Kn of more than 10, while the fraction of the e phase was 94.2 pct.Afterward, as the process progressed at a Kn of 1.0, the fraction of the c¢ phase increased to 87.4 pct, and the fraction of the e phase decreased to 12.6 pct.
