    Presented at ICALEO 2011

    Grain boundary engineering (GBE) became a viable means of enhancing the bulk properties of conventional polycrystalline materials. In fact, intergranular corrosion (IGC) starts from surface and gradually penetrates into interior of the component. Therefore, grain boundary engineering the near surface of the specimens will benefit for improvement of IGC resistance.
    The aim of this presentation is to investigate the effect of laser shocking and annealing treatment on the nea...

    Fusing of glass tubes for solar thermal collectors is dominated by the flame based heating and melting technology. The low energy transfer efficiency of the flame in conjunction with long process times, leads to massive gas consumption. Consequently, the use of high amount of energy for fusing raises the interest to substitute this process by a more efficient one...
