摘要
随着科技的迅猛进步,对材料性能提出了更为严格的要求,研究对纳米级合金的制备以及合金特性进行了深入研究.首先对纳米级合金材料实施选取,了解纳米级合金元素的制备过程.通过机械合金化法获得球磨机内物料转速不同的三种状态,通过还原法将金属离子还原,然后与修饰剂发生相互作用,从而合成具有修饰剂表面处理的合金颗粒.运用能源色散X射线光谱,依据测量材料中元素的X射线特征峰来确定其化学组成,可以获取样品不同区域的元素分布信息,进一步研究材料的组成和性质.实验结果表明,H418钢塑韧性和硬度最高,H419钢强度最高,H407钢强度和硬度最低.H418钢的第二相尺寸最小,呈现出最大的弥散程度;相比之下,H419钢的第二相尺寸最大,且其数量较多.
With the rapid progress of technology,stricter requirements have been put forward for material properties.This article conducts in-depth research on the preparation and alloy properties of nanoscale alloys.Firstly,select nanoscale alloy materials and understand the preparation process of nanoscale alloy elements.Three different states of materials in the ball mill with different rotational speeds were obtained through mechani-cal alloying.Metal ions were reduced by the reduction method and then interacted with the modifier to synthesize alloy particles with surface treatment of the modifier.By using energy dispersive X-ray spectroscopy to determine the chemical composition of elements in materials based on their X-ray characteristic peaks,the distribution in-formation of elements in different regions of the sample can be obtained,further studying the composition and properties of the material.The experimental results show that H418 steel has the highest plastic toughness and hardness,H419 steel has the highest strength,and H407 steel has the lowest strength and hardness.The second phase size of H418 steel is the smallest and exhibits the highest degree of dispersion;In contrast,H419 steel has the largest second phase size and a larger quantity.
