| Abstract: | The performance of rails in service is greatly influenced by the presence of metallurgical defects. Hydrogen-induced shatter
crack is the most prominent among these and has been discussed in detail. Principal causes of rail failure have been outlined
and different types of defects leading to failure of rails during service have been documented. Wear of rails which accounts
for reduced life has been considered. Influence of microstructure on wear rate has been described. |
