A Consideration on the Wetting with Brazing Alloys

Wettability of Brazing Filler Metals on Copper and Copper Alloys

The possibility of alloying can not be avoided at the interface between molten brazing filler metal and base metal in brazing, so the wettability of brazing filler metal can not be easily explained theoretically. We used the original apparatus for wettability test and investigated the relation between the wettability of brazing filler metals of Ag-P-Cu and Ag-Cu-Zn-Cd systems on copper and the ...

Wetting phenomena in bcc binary alloys

The wetting behavior at the free (100) surface of a bcc binary alloy exhibiting a continuous order-disorder transition in the bulk is investigated theoretically, using a model equivalent to a bcc Ising antiferromagnet in an external magnetic field. Its salient feature is the generation of an effective ordering surface field , g1 6= 0, for certain symmetry-breaking surface orientations like (100...

qfd planning with cost consideration in fuzzy environment

در عصر حاضر که رقابت بین سازمان ها بسیار گسترش یافته است، مطالعه و طرحریزی سیستم های تولیدی و خدماتی به منظور بهینه سازی عملکرد آنها اجتناب ناپذیر می باشد. بخش عمده ای از رقابت پذیری سازمان ها نتیجه رضایتمندی مشتریان آنها است. میزان موفقیت سازمان های امروزی به تلاش آنها در جهت شناسایی خواسته ها و نیازهای مشتریان و ارضای این نیازها بستگی دارد. از طرفی کوتاه کردن زمان ارائه محصول/خدمات به مشتریان...

Effect of microtextured surface topography on the wetting behavior of eutectic gallium-indium alloys.

Liquid-embedded elastomer electronics have recently attracted much attention as key elements of highly deformable and "soft" electromechanical systems. Many of these fluid-elastomer composites utilize liquid metal alloys because of their high conductivities and inherent compliance. Understanding how these alloys interface with surfaces of various composition and texture is critical to the devel...
