Hydrogen resistance and trapping behaviour of a cold-drawn ferritic–pearlitic 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...

Some Aspects of Stored Energy and Recrystalliz/ltion Texture in Cold Drawn Steel Wire

Different investigations have shown that an orientation dependence of elastic stored energy exists in cold rolled low carbon steels [i-6]. These stored energy values were estimated from Xray line broadening and electron microscope estimates of subgrain size and misorientation. The sequence of stored energy as a function of orientation was found to depend on the type of steel. In some investigat...

Trapping cold molecular hydrogen.

Translationally cold H(2) molecules excited to non-penetrating |M(J)| = 3 Rydberg states of principal quantum number in the range 21-37 have been decelerated and trapped using time-dependent inhomogeneous electric fields. The |M(J)| = 3 Rydberg states were prepared from the X (1)Σ(+)(u)(v = 0, J = 0) ground state using a resonant three-photon excitation sequence via the B (1)Σ(+)(u)(v = 3, J = ...

Recrystallization and Grain Growth of Cold drawn Gold bonding Wire

Recrystallization and grain growth of gold bonding wire have been investigated with Electron Back Scatter Diffraction (EBSD). The bonding wires were wire-drawn to an equivalent strain greater than 11.4 with final diameter between 25 and 30μm. Annealing treatments were carried out in a salt bath at 300°C, 400°C for 1 min, 10 min, 60 min, and 1 day. The textures of the drawn gold wires contain ma...
