For example, MGs commonly show very high strength [8, 9], and thus they are very promising materials for fabrication of aircraft frames. High hardness and excellent resistance to wear make them potential candidates for contact applications such as phone’s shell. The high elasticity makes them suitable for applications as golf clubs or spring [10]. High-strength, low elastic modulus, and good corrosion resistance make MGs promising applications as biomedical materials [2]. Although great progress has been achieved for MGs in the past decades, their practical applications as structural and functional materials are greatly impeded due to three main problems [1, 11], that is, dimensional limit, poor tension plasticity, and hard-to-machining and shaping.","PeriodicalId":306056,"journal":{"name":"Metallic Glasses - Properties and Processing","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124889154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Berradja","doi":"10.5772/INTECHOPEN.78233","DOIUrl":"https://doi.org/10.5772/INTECHOPEN.78233","url":null,"abstract":"A fundamental quest of modern triboelectrochemistry is to unravel the prevailing failure mechanisms when surface interactions are operated in corrosive environments and to study how these influence the performance of materials and tools. Both system and materi - als oriented approaches are thus required to deal with the electrochemical and physicochemical changes of matter due to the influence of a mechanical sliding energy between the two contacting surfaces (i.e. tribocorrosion damage). In this chapter, metallic glass material concepts used in environments where tribocorrosion occurs are described. Concepts to act in opposition to wear and corrosion are briefly reported. In particular, a description is given of different groups of metallic glasses designed to withstand the effects of combined and uncoupled wear and corrosion. Metallic glass composition, structural effect, crystallization level, passive film formation, microhardness are often viewed as the most critical elements in the performance of tribocorrosion of metallic glasses. Interactions between wear and corrosion mechanisms are identified along with some models that aim to inform metallic glass selection and predict performance.","PeriodicalId":306056,"journal":{"name":"Metallic Glasses - Properties and Processing","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122249949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the poor processability of metallic glasses greatly hindered their engineering applications. Though some techniques have been developed to fabricate metallic glass components, the unique superplasticity of supercooled liquid metallic glasses attracts enduring attentions, which allows thermoplastic forming of metallic glasses on length scales ranging from atomic-size to centimeter and especially offers an alluring prospect in the field of microfabrication. While some pivotal aspects during thermoplastic forming of metallic glasses should be addressed, for example, the evaluation of thermoplastic formability and its relationship with material flowing characteristic, the required ther - moplastic forming techniques for processing MG components with high quality and the potential applications of these thermoplastic formed textures are compressively reviewed in this chapter.","PeriodicalId":306056,"journal":{"name":"Metallic Glasses - Properties and Processing","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125270996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, for efficient use of these novel mate rials with an interesting combination of properties, it is necessary to fully characterize them for their mechanical and electrochemical properties. Studies on the effects of chemi cal parameters (pH, temperature, concentration of reagent) and tribological parameters (load, sliding speed, counterbody, contact configuration) on the kinetics of the reaction (i.e., the material removal rate) supply information on the dominant mechanisms govern - ing the tribo-electrochemical behavior of metallic glasses. Although considerable efforts have been made to characterize their mechanical, corrosion, and magnetic properties, the study of their tribocorrosion patterns is in a rather unsatisfactory state, and very lim ited information is available. It is the purpose of this chapter to provide an overview of basic information on the tribo-electrochemical properties of most metallic glasses. This becomes crucial when such materials are to be considered in systems where solid sur- faces are prone to mechano-chemical transformation processes.","PeriodicalId":306056,"journal":{"name":"Metallic Glasses - Properties and Processing","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121285678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
