Ni-based brazing filler metals are widely used for joining stainless steels and heat resistant alloys etc. In history, pastes which are mixture of atomized powder and organic binder were firstly commercialized in 1930’s and foils produced with rapidly solidification technology were developed in 1980’s and have been used in variety of applications such as industrial heat exchanger, EGR (Exhaust Gas Recirculation) cooler, and so on. There are few studies on the effect of morphic difference between foil and paste on brazeability. Since it is very important to clarify such effect from engineering point of views, we investigated the effect of morphic difference between foil and paste on brazeability with spreading and gap-filling test. |
