The room temperature X-ray diffraction results confirmed the coexistence of the two tetragonal and hexagonal phases for x ≤ 0.050 of Zr content. While above 0.050 the hexagonal phase disappeared in benefit of the tetragonal phase. The Raman results confirmed the formation of these phases obtained by XRD. The scanning electron micrographs consisted of both spherical and straight grain forms for x=0.000 to 0.075, and only spherical grain form for x=0.100 attributed to the tetragonal phase. Also, the grain size increased accompanied by a decrease in density of ceramics with increasing Zr content up to 0.050 then decreased accompanied by an increase in density. Detailed studies of dielectric permittivity measurement provided a presence of two anomalies Te and TR-O at different temperatures, with a relaxation phenomenon and diffuse behavior which was very important for ceramic at x=0.075 of Zr content. The dielectric permittivity values of the two anomalies of Zr substituted BaTi0.80Fe0.20O3 ceramics increased with the increase of Zr content and the dielectric loss was minimal at x=0.100 of Zr content. The conductivity increased with increasing of Zr substitution from 0.025 to 0.075 levels while for x = 0.100 the dielectric conductivity decreased. And the Cole-Cole analysis indicated a negative thermal resistivity coefficient (NTCR) behavior of these materials and ideal Debye-type behavior.","PeriodicalId":14603,"journal":{"name":"Iranian Journal of Materials Science and Engineering","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44705949","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}

The photocatalytic dye degradation study of pure CuO nanostructure particles are analysed against two azo dyes (Direct black 38 (Black-E) and Congo red) under ultraviolet (UV) and solar irradiation. The release of major active species (*OH) in the photocatalytic degradation by as prepared CuO nanostructure particles were investigated by photoluminescence (PL) spectra with two different excitation wavelength (325 and 355nm). The band gap of CuO nanostructure particles was calculated from diffuse reflectance spectra. The photocatalytic effect of CuO nanostructure particles is confirmed by the UV – Vis and photoluminescence spectra and from the kinetic studies under UV and solar radiations. The photocatalytic degradation results revealed that 16.35 and 7.5% of black E and Congo red dye was degraded under UV, while the degradation was 47.2 and 17.6% under solar light. The influence of pH on the photodegradation and change in the reaction temperature under solar irradiation were also investigated.","PeriodicalId":14603,"journal":{"name":"Iranian Journal of Materials Science and Engineering","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46881495","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}

In this work, we made layers of chromium borides and chromium carbides on the surface of low carbon steel through some specific treatments. For chromium borides, the boriding treatment in a solid medium at 900°C for 4 h was followed by chromium electroplating on the steel surface and finally the application of annealing treatment at 950°C for 1 and 2 h. For chromium carbides, the cementation in a solid medium was followed by electroplating of chromium on the surface and finally the application of annealing treatment in the temperature range between 500 and 1100°C for 1 h. The results showed that, in the first case, boron diffusion and chromium deposition led to chromium borides on the treated surface. Similarly, for the second case, the cemented layer and the chromium deposited on the surface combined to form chromium carbides on the treated surface after annealing. The characteristics of the chromium borides and chromium carbides obtained were very similar to those of chromium borides and chromium carbides obtained by other processes.","PeriodicalId":14603,"journal":{"name":"Iranian Journal of Materials Science and Engineering","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45287871","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}

The specimens were subjected to three different heat treatment cycles in which the Infrared heating (IR) were used as the heating medium at the ageing stage, and the liquid nitrogen and water were used as the quenching mediums. The ageing temperature and time were 1900C and from 2 to 10h respectively. The results indicated that by using IR at the ageing stage, the hardening rate enhanced because the rapid heating via this method led to faster diffusion of the alloying elements. Moreover, the high density of nanosized precipitates formed during ageing was another reason for higher strength and ductility. Cryogenic treatment had a negligible effect on both the microstructure and tensile properties. However there was an improvemnet in the ductility to some extent. Overall, the combination of a high heating rate and cryogenic treatment led to the highest mechanical properties. SEM micrographs of the fracture surface demonstrated that in Cryogenic treatment plus Artificial Ageing (CAA) condition, the surface was fully covered by deep dimples in contrast to the Cryogenic treatment plus Infrared Heating (CIR) and Water-Quench plus Infrared Heating (QIR) conditions which contained shallwer dimples. Some facets were also observed in the latter samples.","PeriodicalId":14603,"journal":{"name":"Iranian Journal of Materials Science and Engineering","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42683114","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}
