CSL boundary is higher, reaching 56.3%. In the HAZ, the MADGB of the austenite
has a bimodal distribution characteristic. The frequency of the 3 CSL boundary
and HAGB decreased, and the frequency of the LAGB increased. Affected by the
welding thermal cycle, the frequency of 3 CSL boundary of the austenite in the
WM decreases to 11.3%. The ability to hinder HAGB migration is reduced.
10.4.4 Mechanical Properties
The sample dimensions for MP tests are shown in Fig. 10.39. The tensile test, bend
test and Charpy impact test were conducted according to ASTM E8 [42], ASTM
E290 [43] and ASTM A370 [44], respectively.
