Metals with wide stacking faults (low SFE) strain-harden more rapidly, twin easily on annealing, and shows a different temperature dependence of flow stress than metals with narrow stacking faults.

Metals with wide stacking faults (low SFE) strain-harden more rapidly, twin easily on annealing, and shows a different temperature dependence of flow stress than metals with narrow stacking faults. Correct Answer True

The statement is true and very important. Metals with high SFE have a deformation substructure of dislocation tangles and cells, while low-SFE metals show deformation substructure of banded, linear arrays of dislocations.

If the specimen is deformed plastically beyond the yield stress in one direction, e.g., tension and then after unloading it is loaded in the opposite direction, e.g., compression, it is found that the yield stress is less than the original yield stress. This dependence of yield stress on direction loading is called ____________
In an adjacency list representation of an undirected simple graph G = (V, E), each edge (u, v) has two adjacency list entries: [v] in the adjacency list of u, and [u] in the adjacency list of v. These are called twins of each other. A twin pointer is a pointer from an adjacency list entry to its twin. If |E| = m and |V| = n, and the memory size is not a constraint, what is the time complexity of the most efficient algorithm to set the twin pointer in each entry in each adjacency list?
