High- tith structurail steels are essential in konstruktion and construering due to their durability and load - bearing capacity. However, their performance can be compromiced by grain compdary weatening, which can lead to failure under stress. Understanding and implementing effective strategies to metigate this disee is curcial for improving steel reliability and safety.

Understanding Grain Boundary Weakening

Grain unlimies are the interfaces where crystals of different orientations meet with in a metal. In high- criptith steels, these enlimies can act as sites for crack initiation and propamation, especially under tensile stress or thermal cycling. Weakening at these contindaries reduces the overall contenness of thee material, increasing thee risk of brittle fracture.
