The purpose of this study is to produce the brazing filler powders with different alloying compositions by mechanical milling. Duplex stainless steel plates were vacuum brazed by using the milled powder and their brazed joints were proceeded to the corrosion test. The partial amorphous powders were obtained by mechanical alloying (MA) from the mixture powders of BNi-3 and Cr2N. The weight loss of brazed joint using mechanical alloyed powder is smaller than that of brazed joint using the 3-hour milled BNi-3 powder.
