2.2 Methods
The welding heat cycle of CGHAZ was simulated by
Gleeble-3500 thermal simulation testing machine. The
sample was made laterally with 10 mm 9 10 mm 9
55 mm; the notch was opened at the center of solder joint
connected by a thermocouple; and then, the impact test as
the Charpy V-notch was carried out. The heating rate is
130 ()s-1 during simulation of the thermal cycling, peak
