SUMMARY
Grain boundary sliding is a critical factor in the creep behavior of materials, and engineers can mitigate this phenomenon by designing components with larger grains or adopting a columnar grain structure. Larger grains reduce the number of grain boundaries, thereby minimizing sliding. While columnar grains may seem more prone to sliding due to their parallel arrangement, their structure can actually enhance resistance to creep under certain conditions. Understanding the relationship between grain structure and creep mechanisms is essential for effective material design.
