The invention relates to a preparation and forming method for a complex runner die steel material, and belongs to the field of composite materials. Pure die steel powder is reinforced by using superfine diamond powder particles. The processing powder of the powder forming technology comprises the following materials: 1) diamond powder with uniform particle size; 2) die steel powder with uniform particle size; and (3) diamond/die steel composite material powder is obtained by reinforcing the die steel powder through diamond particles, and then the powder is formed through a powder forming technology, so that a composite material finished product with high hardness, high strength and high thermal conductivity is obtained. 本发明涉及一种用于复杂流道模具钢材料的制备及成形方法，属于复合材料领域。本发明使用极细金刚石粉末颗粒增强纯模具钢粉末。粉末成形技术加工粉末，包括以下材料：1)粒径均匀的金刚石粉末；2)粒径均匀的模具钢粉末；3)通过金刚石颗粒增强模具钢粉末，得到金刚石/模具钢复合材料粉末，再通过粉末成形技术对粉末进行成形，从而得到具有高硬度、高强度、高导热性的复合材料成品。
