Abstract: A multi-element alloy material consists of Al, Cr, Fe, Mn, Mo and Ni. From an outer surface to a center of the multi-element alloy material exhibits a hardness gradient from high to low. A method of manufacturing a multi-element alloy material with hardness gradient includes melting and casting metals with a metal combination of Al, Cr, Fe, Mn, Mo and Ni to form an alloy body, subjecting the alloy body to a homogenization treatment, and subjecting the homogenized alloy body to a high temperature treatment to perform precipitation hardening at surface of the alloy body by heating, thereby forming a multi-element alloy material having hardness gradient.
Abstract translation: 多元素合金材料由Al，Cr，Fe，Mn，Mo和Ni组成。 从多元素合金材料的外表面到中心显示从高到低的硬度梯度。 制造具有硬度梯度的多元素合金材料的方法包括用Al，Cr，Fe，Mn，Mo和Ni的金属组合熔融和铸造金属以形成合金体，对合金体进行均化处理，以及 对均质化合金体进行高温处理，通过加热在合金体的表面进行析出硬化，由此形成具有硬度梯度的多元素合金材料。
