摘要

Provided are an apparatus for producing a compound powder, a method for producing an iron-boron compound powder using the apparatus, a boron alloy powder mixture, a method for producing the boron alloy powder mixture, a combined powder structure, a method of manufacturing the combined powder structure, a steel pipe and a method of manufacturing the steel pipe. The method for producing the boron alloy powder mixture includes: preparing a mixed powder containing a boron-iron alloy powder and a target powder; Heat-treating the mixed powder to at least boronate at least a portion of the target powder and to at least partially boronate a portion of the boron-iron alloy powder, whereby the boron-iron alloy powder is deborated to lower the melting point of the boron-iron alloy powder.
