A sort of Ni-base thin strip used as a filler metal was made by using the melt spinning of rapid solidification techniques.The
extensibility and sew fillingability were taken measurements by means of physical experimental method of the filler metals.For evaluating the capability of the filler metal,it was contrasted with a foreign advanced solder with the similar components.By using SEM、EDX and etc,the microstructure and chemical elements of
the brazed joints using two kinds of filler metals have been observed and analyzed comparatively,so that a general quality estimates can be given for the domestic filler metal.The results indicate that the continuous thin strip of even thickness and whose length can be changed from several meters to several decameters,well suited as a filler metals,was made by using melt spinning in rapid solidification techniques;The extensibility and
sew filling-ability of self-made solder is better than that of the foreign advanced one with the similar components;The chemical elements of the brazed joints using two kinds of filler metals are nearly the same and M6C carbide is precipitated mainly in matrix.
