YS_L (MPa) for PWHTed CA6NM samples having different FZ/GL ratios.

Sample	T1 FZ/GL = 0.9	T2 FZ/GL = 0.45	T3 FZ/GL = 0.35	T4 FZ/GL = 0.2	Average YSL (MPa)
FZ	727.7	728.4	725.5	727.1	727.2
HAZFZ	738.8	741.3	739.8	740.1	740.1
HAZBM	—	718.0	706.0	711.9	712.0
BM	—	—	663.0	663.3	663.2

Region of strain localization and failure; region of peak hardness in HAZ close to FZ; HAZ just adjacent to BM.
