Rapid Spheroidization Annealing Technique of Structural Steel Wire Rod

Stainless steel wire suture technique in thoracic surgery.

Before embarking upon any new surgical procedure or technique three conditions need to be fulfilled. First, it must be shown to be necessary, secondly, there must be sufficient experimental evidence to justify a trial of the new method; and tlhirdly, any advantage the new may appear to have over the old must be shown to possess statistical significance before its final adoption is justified, un...

Annealing of Wire Products: Atmospheres

The purpose of a furnace atmosphere varies with the desired end result of the heat-treating process. In general, the atmospheres used in the heat-treating industry have one of two common purposes: •To protect the material being processed from chemical reactions that could occur on their surfaces (e.g. oxidation), that is, to be passive (or chemically inert) to the metal surface. •To allow the s...

Phase field study of interfacial diffusion-driven spheroidization in a composite comprised of two mutually insoluble phases.

The phase field approach is a powerful computational technique to simulate morphological and microstructural evolution at the mesoscale. Spheroidization is a frequently observed morphological change of mesoscale heterogeneous structures during annealing. In this study, we used the diffuse interface phase field method to investigate the interfacial diffusion-driven spheroidization of cylindrical...

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...
