Abstract

The paper presents the results of experimental studies in the scope of formation of bulky aluminum based composite materials (CM) with carbon nanofibers (CNF), including the research methods of hot extrusion and rolling. Extrusion manufacture of bulky composite materials contributes to obtain billets with a minimum compression degree (λ = 1.5). To reduce shear deformations and formation of pores in extruded billet, the extrusion process modes were selected experimentally. In the course of further rolling operation, mechanical properties increase twice and inhomogeneity is compensated after significant compression of the extrusion billets, and the shear deformations are reduced in full volume of the material. Bulky materials gain high hardness, wear resistance and strength. The economically alloyed composite material has feasible prospects to be applicable in lightweight structures for aviation and automobile industries.

摘要

本文介绍了在碳纳米纤维（CNF）形成大块铝基复合材料（CM）的范围内的实验研究结果，包括热挤压和热轧的研究方法。大块复合材料的挤压制造有助于获得具有最小压缩度 (λ = 1.5) 的坯料。为了减少挤压坯料中的剪切变形和孔隙的形成，通过实验选择挤压工艺模式。在进一步的轧制过程中，挤压坯料的显着压缩后，力学性能增加两倍，不均匀性得到补偿，材料全体积的剪切变形减小。大块材料获得高硬度、耐磨性和强度。
