Their crystalline structure and crystallization behavior are studied by means of X-rays Diffraction (XRD) and Polarizing Optical Microscopy (POM) and their dielectric response via Broadband Dielectric Spectroscopy (BDS). XRD results suggest transformation of the α΄-crystal form of PLLA into the more stable α-form at elevated crystallization temperatures. According to POM observations all samples are fully crystallized for crystallization times of 1h. The growth size of PLLA spherulites increases linearly with time, while the growth rate is essentially independent of nanofiller content. BDS analyses reveal the presence of three relaxation processes in PLLA/TiO 2 nanocomposites, at temperatures ranging from 20°C to 140°C. These mechanisms are attributed to α–relaxation of the polylactide matrix, the Maxwell–Wagner–Sillars (MWS) interfacial polarization effect and the dc conductivity effect (CR), in terms of increasing temperature. The dynamics of all three relaxation mechanisms and the fragility index of the PLLA matrix appear independent of filler loading.","PeriodicalId":297187,"journal":{"name":"Modern Concepts in Material Science","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130612156","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}

These binary compounds present unique properties besides shape memory effect (SME), super elasticity (SE). Among SMA, the NiTi (Nitinol) is the most relevant intermetallic compound due to its functional and excellent mechanical properties [1-2]. The unforeseen functional properties of SMA are due to a reversible martensitic transformation between a stable high-temperature austenitic phase (B2) and low-temperature martensitic phase (B19’). The martensitic transformation can occur directly (B2 ⬌B19’) or via R-phase [3]. The super elasticity results from the stress-induced martensitic transformation (SIM) between austenite and martensite[4,5]. Moreover, the shape memory effect is also caused by thermal-induced martensite transformation (TIM) [3]. This behavior lets to their application as actuator and/or sensor, because their structures may detect the mechanical stresses and thermal changes around them and reply almost instantly to the external variation [1-7].","PeriodicalId":297187,"journal":{"name":"Modern Concepts in Material Science","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125640459","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}

While the individual materials can be well characterized e.g. by their physical and chemical properties the description and prediction of the friction and wear behaviour is not an easy task. There is no uniform, analytical calculation method, because the behaviour of the structural materials depends on the operating conditions and the effects occurring during operation, thus, the tribological behaviour is system dependent. In order to have information about wear, friction and heat generation during operation, it is advisable to use the modelling method. The result of either mechanical or numerical modelling can help machine designers. The use of simplified models performed under laboratory conditions (DIN50322, testing category VI.) is very common, where relative comparison of friction materials is possible under fixed conditions. The laboratory tribotest equipments are usually suitable for online data collection, so that friction force, heat generation, wear and deformation can be continuously recorded during a sliding process. These datasets provide an opportunity not only for primary trend analysis of the measured quantities, but also for in-depth analysis of the relationships between tribological trends and material characteristics. Hundreds of articles have been published in the tribological literature where wear, surface deformation, or friction have been evaluated as a function of some material characteristics or simple combinations thereof. The first famous results e.g. in the field of abrasion wear, the wear estimates published by Lancaster in the late 1960s [1]. Not highlighting each work, overall the surface hardness (H), tensile modulus of elasticity (E) and tensile strength (R) were mainly in focus, as a function of which tribological processes, the friction and wear behaviour of materials were evaluated.","PeriodicalId":297187,"journal":{"name":"Modern Concepts in Material Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121333350","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}
