Case study of severe strip breakage in rolling mill

2016-08-30_12h43_54A case study published in « Case Studies in Engineering Failure Analysis » – april 2016.

In this paper, a case of severe strip breakage in rolling mill of Thin Slab Casting and Rolling (TSCR) shop of TATA Steel, Jamshedpur is presented. Visual observation revealed complete splitting with material missing along the central axis of the strip. Presence of defects in form of white stringers, white patches and holes were observed along the same axis just ahead of split location.

Hydrogen Embrittlement of Industrial Components: Prediction, Prevention, and Models

2016-07-05_17h26_56

A paper find on ResearchGate and published in « Corrosion-Houston_Texas « – July 2016.

This paper gives an overview of the application of a model for structural integrity analysis of boiler tubes made of plain carbon steel exposed during operation to a local corrosion process and multiple hydrogen assisted degradation processes: hydrogen embrittlement and high-temperature hydrogen attack. The model is based on the correlation of mechanical properties to scanning electron microscopy fractography analysis of fracture surfaces in the presence of simultaneously active hydrogen embrittlement micro-mechanisms. The proposed model is practical for use as a predictive maintenance in power plants, as it is based on the use of standard macro-mechanical tests.
