Relaxation of PC Steel Wire

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...

Stress relaxation properties of prestressed steel wires

In this study, stress relaxation phenomenon has been examined generally. Experiments were carried out on carbon steel wires with diameter 8 mm which are particularly used in prestressed concrete composites. Thermomechanically heat treatment was also carried out on this wire in order to relieve the residual stresses accumulated after the cold work. The heat treatment temperature and the stretch ...

Optimization of Operations in a Steel Wire Manufacturing Company

The project was conducted in a high quality steel wire manufacturing company with the production capacity of over 120,000 tones/annum. The wire drawn from the high speed wire drawing (KOCH) machine is fed as the raw material for BEKEART (zinc coating galvanization) furnace. The problem faced by the company is the variability in the amount of input to the furnace, which results from the breakdow...

Characterisation of severely deformed austenitic stainless steel wire

The microstructure of 8 mm diameter wire produced by the severe deformation of 316L austenitic stainless steel has been examined using TEM and X-ray diffraction. The deformation imparted amounts to a true strain of 6.3. Data from previous studies on strain induced transformation of this steel have been combined with new results to show that true strains .2 are required in order to observe mecha...
