Static Strain Aging Behavior of Low Carbon Steel Drawn Wire
The static strain aging is a phenomenon that can change the mechanical properties of low carbon steels. Thus, the static strain aging behavior of low carbon steel wires after drawing process is studied. To do so, the wires are austenitized at different temperatures and cooled in different rates. Then the wires are drawn and aged at a specific temperature and time. Before and after aging of each...
متن کاملBending Fatigue Failures in Valve Steel
In the present paper the effect of defects (viz. pits, gouges and oxide inclusions) will be reported. Although certain defects were uniformly distributed over the specimen surface, the majority of all fractures started in the edge region. An explanation to this behaviour is presented in terms of stress enhancement in the edge regions due to edge deflections.
متن کاملAnalysis of Fatigue Crack Paths in Cold Drawn Pearlitic Steel
In this paper, a fracto-metallographic analysis was performed on the cracked specimens of cold drawn pearlitic steel subjected to fatigue tests. Fatigue cracks are transcollonial and exhibit a preference for fracturing pearlitic lamellae, with non-uniform crack opening displacement values, micro-discontinuities, branchings, bifurcations and frequent local deflections that create microstructural...
متن کاملA comparison of two reciprocating instruments using bending stress and cyclic fatigue tests.
The aim of this study was to comparatively evaluate the bending resistance at 45º, the static and dynamic cyclic fatigue life, and the fracture type of the WaveOne (Dentsply Maillefer, Ballaigues, Switzerland) 25-08 and Reciproc (VDW, Munich, Germany) 25-08 instruments. A total of 60 nickel-titanium (NiTi) instruments (30 Reciproc and 30 WaveOne) from three different lots, each of which was 25 ...
