STUDIES ON GRAIN SIZE CONTROL OF ALUMINIUM SHEETS

Grain size effects in the forming of ultra-thin sheets

Introduction The number of micro scale applications of metals is growing rapidly. Progressive miniaturization has become a decisive characteristic of developments in electronic devices (Figure 1) or electronically controlled mechanical systems. Along with the miniaturization so-called size effects occur in sheet metal manufacturing processes. These effects are assumed to be caused by changes in...

Scheduling and grain size control

Locality and storage management considerations for fork-join parallelism lead to the loss of the important List Scheduling property. The worst case performance of the constrained scheduling policies, called PaH and ToS, is very bad: (nearly) all parallelism is lost. “Practical” performance, however, differs radically from worst case performance. The PaH and ToS policies perform on average withi...

Effects of temperature gradient magnitude on bending angle in laser forming process of aluminium alloy sheets

Laser forming is a thermal forming process which uses laser beam irradiation to produce the desired final forms. In this article, the effect of temperature gradient across  Al 6061-T6 aluminum sheets on bending angle is studied. Input parameters including laser power, scan velocity, beam diameter, and sheet thickness are the effective process parameters which influence the temperature gradient....
