Abstract

Full text

There were some errors in the original publication [1]. Some texts need to be updated in Sections 3.2.1 and 4.

In Section 3.2.1, paragraph 3, the sentence

• u ≈ 0.44 mm (A1—384 counts)—see Figure 6a;

• u ≈ 1.09 mm (A2—334 counts)—see Figure 6b;

• u ≈ 1.59 mm (A3—389 counts)—see Figure 6c.

• should be updated to the following version:

• u ≈ 2.31 mm (A1—434 counts)—see Figure 6a;

• u ≈ 2.09 mm (A2—384 counts)—see Figure 6b;

• u ≈ 2.39 mm (A3—589 counts)—see Figure 6c.

In Section 3.2.1, paragraph 5, the sentence “In specimen B1, the highest AE burst (331 counts) was recorded at u ≈ 0.164 mm, indicating a more diffuse deformation mechanism and a lower dislocation concentration in the initial plasticity range (see Figure 7a).” should be updated to the following version:

“In specimen B1, the highest AE burst (131 counts) was recorded at u ≈ 0.164 mm, indicating a more diffuse deformation mechanism and a lower dislocation concentration in the initial plasticity range (see Figure 7a).”

In Section 4, paragraph 1, the sentence “The very early RA-value maxima (e.g., RA_max_ = 520 at u ≈ 0.052 mm for A2) reflect abrupt dislocation avalanches, whereas the highest Counts to Peak values recorded later (u ≈ 0.44–1.59 mm) correspond to the development of strain localisation and the initiation of microcracks.” should be updated to the following version:

“The very early RA-value maxima (e.g., RA_max_ = 520 at u ≈ 0.052 mm for A2) reflect abrupt dislocation avalanches, whereas the highest Counts to Peak values recorded later (u ≈ 2.31–2.39 mm) correspond to the development of strain localisation and the initiation of microcracks.”

In Section 4, paragraph 5, the sentence

• Counts to Peak ≥ 530–600 and characteristic RA-value change:

• ∘RA ≤ 50–150 (A);

• ∘RA ≈ 100–300 (B);

• ∘RA ≥ 300–450 (C).

• should be updated to the following version:

• Counts to Peak reaches a critical level characteristic of a given material condition, evaluated in the damage initiation window (near the onset of strain localisation), with a characteristic change in the RA-value:

• ∘CTP ≈ 350–600 and RA ≈ 100–300, corresponding to an impulsive AE response with pronounced, short-duration peaks and no sustained elevated RA level in the damage initiation stage, which is typical of a strain-hardened, quasi-brittle deformation mechanism (A);

• ∘CTP ≈ 250–600 and RA ≈ 200–500, with the maximum RA correlated with the strain localisation area, indicating a transitional deformation mechanism with a mixed contribution of dislocation slip and frictional–ductile processes (B);

• ∘CTP ≈ 300–380 and RA ≥ 300–450, with low characteristic RA values during most of the loading process and a pronounced increase in both parameters immediately before fracture, which is characteristic of a fully ductile failure mechanism governed by crack-surface separation and friction (C).

In Section 4, paragraph 5, the sentence “1200–1500 MPa (C).” should be updated to “800–1500 MPa (C).”

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
