A new case study in « Case Studies in Engineering Failure Analysis » of October 2015.
Tyre bead grade wire is used for tyre making application. The wire is used as reinforcement inside the polymer of tyre. The wire is available in different size/section such as 1.6 mm to 0.80 mm thin Cu coated wire. During tyre making operation at tyre Manufacturer Company, wire failed frequently. In this present study, different broken/defective wire samples were collected from Wire Mill for details investigation of the defect. The analysis revealed that, white layer of surface martensite was formed and it was caused the final breakage of wire. In this study they have also discussed about the possible reason for the formation of such kind of surface martensite (hard-phase).
