Abstract

The present study examined the influence of ball milling on the evolution of microstructure, texture, and grain boundary distribution in hot press sintered cobalt-based alloy (60Co-15Al-15Ti-5Ta-5Nb). The key findings of this study reveal that the sample that underwent a 20-h ball milling followed by sintering has a high hardness of 1068 HV0.5, a relative sintered density of 85.65 %, and a high strength of 592 MPa. Additionally, it demonstrates that the use of ball milling for more than 20 h decreases the densification, thereby affected their mechanical properties.

球磨对热压烧结钴合金微结构和微纹理演变的影响

本研究探讨了球磨对热压烧结钴基合金（60Co-15Al-15Ti-5Ta-5Nb）微观结构、纹理和晶界分布演变的影响。该研究的主要发现表明，经过 20 小时球磨后烧结的样品硬度高达 1068 HV0.5，相对烧结密度为 85.65 %，强度高达 592 MPa。此外，它还表明，球磨时间超过 20 小时会降低致密化程度，从而影响其机械性能。

期刊介绍： This journal is a platform for publishing innovative research and overviews for advancing our understanding of the structure, property, and functionality of complex metallic alloys, including intermetallics, metallic glasses, and high entropy alloys. The journal reports the science and engineering of metallic materials in the following aspects: Theories and experiments which address the relationship between property and structure in all length scales. Physical modeling and numerical simulations which provide a comprehensive understanding of experimental observations. Stimulated methodologies to characterize the structure and chemistry of materials that correlate the properties. Technological applications resulting from the understanding of property-structure relationship in materials. Novel and cutting-edge results warranting rapid communication. The journal also publishes special issues on selected topics and overviews by invitation only.
