A Review on Cracking in Laser Additive Manufacturing of Nickel‐Based Superalloys: Types, Formation Mechanisms, and Suppression Strategies

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

Reduction of welding residual stress using ultrasonic vibration load (Effects of material properties on reduction rate)

Mechanical Engineering Journal, 2023
Welding is used as a joining method in the construction of many structures. Residual stress is generated near the bead because of locally given heat. It is well known that it degrades fatigue strength. Especially, it is a cause of stress corrosion cracks
