Tearing Topography Surface
Tearing Topography SurfaceIn some cases, a fractographic topography as shown in Fig. 3.45 is found. It consists of very fine "facets" connected by tear ridges and is referred to as tearing topography surface (TTS). This appearance seems to be caused by the particular complex microstructures involved in the fracture. The underlying mechanisms are probably those already described.
Examples of tearing topography surfaces (TTS). In these cases dimple rupture (DR) is also found. (<emphasis role="italic">a</emphasis>)–(<emphasis role="italic">d</emphasis>) HY-130 steel. (<emphasis role="italic">…</emphasis>
