Abstract
Transport by rail is an efficient way of moving goods and people while managing problems such as congestion and the consequences on the environment. The relatively low energy consumption and CO2 emissions are attributed to the low rolling-resistance due to the stiffness of the wheel and rail, leading to small contact area [1]. Investments in rail transportation has boomed in recent years. London, with the oldest underground rail system in the world, has added the Elisabeth Line at a cost of some £14 billion; China now has the largest high-speed rail system in the world. All these developments rely on the safe performance of steel rails, which suffer from two primary damage mechanisms, rolling-contact fatigue caused essentially by repeated contact stresses with the wheel, and a variety of wear mechanisms. Factors such as weldability are important, given that all modern rails are continuous. This review deals with the detailed physical-metallurgy of rail steels, including alloy design, microstructure, variety and choice, and damage mechanisms.
期刊介绍：
Progress in Materials Science is a journal that publishes authoritative and critical reviews of recent advances in the science of materials. The focus of the journal is on the fundamental aspects of materials science, particularly those concerning microstructure and nanostructure and their relationship to properties. Emphasis is also placed on the thermodynamics, kinetics, mechanisms, and modeling of processes within materials, as well as the understanding of material properties in engineering and other applications.
The journal welcomes reviews from authors who are active leaders in the field of materials science and have a strong scientific track record. Materials of interest include metallic, ceramic, polymeric, biological, medical, and composite materials in all forms.
Manuscripts submitted to Progress in Materials Science are generally longer than those found in other research journals. While the focus is on invited reviews, interested authors may submit a proposal for consideration. Non-invited manuscripts are required to be preceded by the submission of a proposal. Authors publishing in Progress in Materials Science have the option to publish their research via subscription or open access. Open access publication requires the author or research funder to meet a publication fee (APC).
Abstracting and indexing services for Progress in Materials Science include Current Contents, Science Citation Index Expanded, Materials Science Citation Index, Chemical Abstracts, Engineering Index, INSPEC, and Scopus.
