Powder metallurgy material and preparation method and application thereof

The invention provides a powder metallurgy material and a preparation method and application thereof, the powder metallurgy material has a particle form, each particle comprises an initial powder metallurgy material, a first material and a binder, the first material is doped in the initial powder metallurgy material, and the binder is used for bonding the initial powder metallurgy material and the first material to each other, wherein the tensile strength of the first material is higher than that of the initial powder metallurgy material. According to the powder metallurgy material, the stress of the powder metallurgy material is reduced compared with that of an initial powder metallurgy material, and therefore the powder metallurgy material can be applied to preparation of products uneven in thickness or stress. 本申请提供了粉末冶金材料及其制备方法和应用，所述粉末冶金材料具有颗粒形式，每个颗粒包括初始粉末冶金材料、第一材料和粘结剂，第一材料掺杂在所述初始粉末冶金材料中，粘结剂用于将初始粉末冶金材料和第一材料相互粘结，其中，第一材料的抗拉强度高于初始粉末冶金材料的抗拉强度。根据本申请实施例的粉末冶金材料，相较于初始粉末冶金材料的应力得到减小，因此能够应用于制备厚度或者应力不均的产品。
