Improved High Tensile Strength Stainless Steel Fine Wire for Spring

Improved Material Models for High Strength Steel

The mechanical behaviour of the three advanced high strength steel grades, Docol 600DP, Docol 1200M and HyTens 1000, has been experimentally investigated under various types of deformation, and material models have been developed, which account for the experimentally observed behaviour. Two extensive experimental programmes have been conducted in this work. In the first, the dual phase Docol 60...

Developing Very Fine Nanopearlitic Structure in a High Carbon Steel Wire before Drawing

The effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. In this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. The results were the minimum interlamellar spacing of 35 nm and maximum ulti...

Lattice strain evolution during uniaxial tensile loading of stainless steel

Applied and residual lattice strains were determined by neutron diffraction during a tensile test of a weakly textured austenitic stainless steel and were compared to the predictions of a self-consistent polycrystal deformation model. Parallel to the tensile axis the model predictions are generally within the resolution of the diffraction measurements, but perpendicular to the tensile axis disc...

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...
