Brittle fracture of Fe –2.2% Si slab

Brittle fracture of Fe –2.2% Si slab - Fractography

Figure 1: Brittle fracture of a silicon electrical steel slab during mill handling. The slab measured 8.5-inch thick x 41-inch wide (21.6-cm x 104-cm).

Figure 2: Coarse columnar grain structure of the Fe –2.2% Si electrical steel slab, etched with nital. The rolling direction is vertical.

Figure 3: Charpy V-notch impact strength curves demonstrate the brittle nature of Fe –Si steels.
