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 ...

Mechanical Properties of Boron Carbide (B4C)

, 2020
Boron carbide (B4C) is one of the most important opaque boride ceramics that has high hardness and Young\u27s modulus that along with low density lead to a significant resistance to ballistic impact and, thus, B4C is broadly used as a protective material.
