Abstract
Phase transformations during melting, isothermal dwell and solidification of composite Al-Si+flux braze material are studied experimentally. A multistep mechanism of melting conjugated with Si diffusion, mushy zone formation and chemical reaction between flux and aluminum oxide is discussed. The impact of different processing parameters on final microstructure is described and quantified.
