摘要

Al-Si和Al-Si- cu系铝合金是机械制造中应用最广泛的材料之一。它们的广泛应用与低成本、高可制造性、优异的多次回收能力和足够的机械性能水平有关。提高Al-Si-Cu合金的力学性能一直是一个亟待解决的问题,通常需要通过多次组分改性来解决。本文研究了Co、V、Mo络合物对广泛应用的AlSi9Cu3(Fe)合金组织相态和力学性能的影响。所有改性添加剂的添加量为0.1-0.2 wt. %。同时,其总含量不超过0.5 wt. %。结果表明,对AlSi9Cu3(Fe)进行钴和钒复合改性后,合金的晶粒细化程度显著提高,强度提高20%以上,同时保持塑性。同时,钴主要起共晶组分改性剂的作用,钒主要起晶粒细化剂的作用。同时用钒和钼对合金进行改性,确保了所有结构部件的细化和强度的提高。这两种成分都起成核作用。同时加入钴和钼表明钴对共晶组分的影响。钼实际上没有成核作用,主要进入含铁相。因此,可以观察到平均力学性能。三重变质可以最大限度地细化所有组织相成分,提高合金的强度。这种合金的最高显微硬度表明在高温下具有潜在的高机械性能。关键词:铸造铝合金,改性,AlSi9Cu3(Fe),组织,相组成,力学性能

Complex modification of AlSi9Cu3(Fe) alloy by using cobalt, vanadium and molybdenum
Aluminum casting alloys of the Al-Si and Al-Si-Cu systems are among the most widely used materials for machine building. Their wide use is associated with low cost, high manufacturability, excellent ability for multiple recycling and sufficient level of mechanical properties. Increasing of Al-Si-Cu alloys mechanical characteristics always remains as a relevant task, which is often solved by several components modification. Presented work is dedicated to investigation of Co, V and Mo complex influence on the structural phase state and mechanical properties of the widely used AlSi9Cu3(Fe) alloy. All modifying additives were added in the amount of 0.1-0.2 wt. %. At the same time, their total content did not exceed 0.5 wt. %. It is shown that the complex modification of AlSi9Cu3(Fe) with cobalt and vanadium contributes to a significant grain refinement and increasing strength of the alloy by more than 20% while maintaining plasticity. At the same time, cobalt mainly performs the function of a modifier of eutectic components, and vanadium plays the role of a grain refiner. Simultaneous modification of the alloy with vanadium and molybdenum ensures refining of all structural components and strength elevating. Both components perform the function of nucleation. The simultaneous addition of cobalt and molybdenum shows the effect of cobalt on eutectic components. Molybdenum actually does not have a nucleating effect and is mainly goes to iron-containing phases. As a result, average mechanical properties can be observed. Triple modification makes it possible to obtain maximum refining of all structural-phase components and increase the strength of the alloy. The highest microhardness of such alloys indicates potentially high level of mechanical properties at elevated temperatures. Keywords: cast aluminum alloys, modification, AlSi9Cu3(Fe), structure, phase composition, mechanical properties.
