Abstract Scope |
Mn-Steels are known for their exceptional wear resistance, fatigue strength and durability. This alloy is particularly most suitable for railway tracks, frogs and crossovers, switches and turnouts and railway sleeper plates. Manufacturing complexity and welding difficulties are very known challenges with Mn-steel alloys. Wire Arc Additive Repair (WAAR) technology has been known for its ability to manufacture/repair different types of steel and difficult to alloys. In the current research, WAAR of worn out Low Mn-steel railway sections was conducted using high Mn-steel wires (14%Mn). Parametric Study was conducted to optimize the deposition variables. Integrity of the deposited layers of the high Mn-steel were evaluated under different processing parameters with particular emphasize on the interface between the two dissimilar Mn-steel compositions. Structural integrity, and structure-property relationships across the full-length of the repaired sections were characterized. |
