摘要

During the writing of the original paper, the hardness graph of weld W3 (forged at 950 ◦C) in Figure 10 was mixed up with the hardness graph of weld W2 (forged at 1150 ◦C). Due to this, it was wrongly assumed that weld W3 did not follow the trend of the other welds (that were forged at higher temperatures) with respect to the width of the heat affected zone. The following changes should be done to Sections 3.1 General and 3.3 Hardness.
