Ni improves toughness in martensitic steels. However, the effect of Si on grain refining and toughness of martensitic steel for high-strength applications including armor grades has not been much studied, which can be also a cheaper alternative repla

Six cold-rolled steel sheet samples having surface defects like slivers and dents have been metallurgically analyzed to identify the reasons for generation of such defects. In all the cases, large inclusions/entrapments were located at the defect sit

Low carbon alloy steels, one alloyed with B and Cr and other alloyed with B, Cr and Nb were made and cast into pencil ingots. These ingots were hot-rolled to 2 mm sheets suitable for hot stamping application in an experimental rolling mill and a deta

Failure of boiler water-wall tubes in a thermal power station is a very common phenomenon. ‘High-temperature creep’ is one of the main reasons behind these failures. A systematic study of the failures may lead to minimization of the failure occur

Steel splice plates are used in power transmission line towers. During service, some of these plates may fail due the loading stress as well as stress generated due to inclement weather condition. One such failed splice plate, cracked in the heel reg

A locked coil track rope (LCTR) is essentially composed of wires (round and rail-shaped) laid helically in different layers. These wire ropes are sometimes used in conveyors carrying empty and loaded buckets in mining areas. During service, such wire
