Fig. 3 An example of the inclusion morphology and content for the prestressing wire is shown: a) AFRS 1255 longitudinal plane (bar = 10µm), and b) NRS 2020 transverse plane (bar = 200µm). More

Fig. 8 An example of a corrosion morphology commonly found in splits and on fracture surfaces of the samples. More

Fig. 13 Fracture surfaces of AFRS Helix 86 showing the ductile-dimple morphology of the fracture initiation zone. The fractures for the wire samples typically had a very ductile appearance, as shown here. Some of the more elongated features are likely a reflection of the pearlite colony More
