Achievement of superior strength in Al–Ni dissimilar joints through designing high-entropy alloy interlayer and post weld heat treatment

Journal of Materials Research and Technology
The formation of brittle intermetallic compounds (IMCs) at the interface during Al–Ni dissimilar joining deteriorates joint strength, thereby limiting their applicability in high-performance engineering structures.

The effect of PWHT on weld properties of titanium alloy for refurbishment of aircraft engine exhaust cone

, 2012
The mounting bolt hole of aircraft engine exhaust cone was found cracked in the weld area. Exhaust cone material is alfa/beta titanium (Ti-6Al-4V) alloy. The cracked section will be repaired by welding to restore its function.
