1. for the preparation of a method for metal/alloy steel function-graded material, it is characterized in that, the method comprises the following steps:

  • The first step, raw material are chosenEach material category participating in preparation is determined according to the composition of metal/alloy steel function-graded material to be prepared, its medium alloy steel uses solder wire material as main material and sends into solder wire convey system, and metal uses metal dust as composite and sends into the powder feeder be connected with described solder wire convey system;

    This bi-material without the need to being pre-mixed according to proportioning, but determines that it is equipped with in the fabrication process;

    Second step, to prepare in the environment of gas shielded arc welding and additional alternating magnetic fieldGradient powder feeding is performed in the mode of coaxial powder-feeding while wire feed bead welding, and according to the content of composite in function-graded material to be prepared, metal powder sending quantity is regulated in real time by the powder feed rate changing described powder feeder, make main material in the mass ratio of silk feeding quantity and powder sending quantity in the unit interval and function-graded material identical with composite mass ratio, in this way, make above-mentioned bi-material be able in weld deposit process, determine that it is equipped with, and realize fully fusion.
