    Page 1 Analysis of Centreline Crack Formation in Billets at NSH, Singapore S Dhakate1, K Koh2, A Lau2, M Desai 2, C Verma 1Tata Steel India, 2NatSteel Holdings Singapore; At NatSteel Holdings, Singapore, cobbles had been reported during rolling of rebars from billets It is important to realise that a colony of pearlite is a bicrystal. Although a steel becomes stronger as the interlamellar spacing is reduced, it does not become tougher because the colony size is what represents the crystallographic grain size. Thus, a propagating cleavage crack can pass undeviated across a colony of pearlite.

    Metal Failure Analysis & Steps to Investigate the Failure

    Metal failure is a common phenomenon when a metal component is subjected to cyclic stresses or overloading. In this article we discuss how to perform a metal fatigue failure analysis to determine the reason for the failure. By this we can be able to take necessary corrective action in design, maintenance, and operation to avoid another failure. Structural Engineering Software for Steel Structures.

With reference to steel pipelines, inspection of sample data from Murtagian's work is simulated and compared with analytically developed ... In this article, we're going to explore the surface crack detection technique, including two of the most common methods for executing this technique. Liquid penetrant testing (PT). Liquid penetrant testing, sometimes referred to as dye penetrant inspection, is one of the most commonly used surface crack detection methods. If the steel is insufficiently tough, the 'crack' can propagate rapidly, without plastic deformation and result in a 'brittle fracture'. The risk of brittle fracture increases with thickness, tensile stress, stress raisers and at colder temperatures. The toughness of steel and its ability to resist brittle fracture are dependent on a number of ...
