It plays a great role to increase the service life of industrial elements. It is broadly applied in chemical, mining, nuclear, power generation, and marine industries. There were a lot of studies done targeting Gas Tungsten Arc Cladding because of its advantages such as user-friendly, low cost, high deposition rate, low dilution, high reliability, etc. The four key features added to the substrate after claddings are dilution of a substrate, microstructure, microhardness, and tribological properties. Considering these features, the current article presents an overview of the Gas Tungsten Arc Cladding technique. The key goal is to reflect on the investigations conducted in the previous decade based on the wear, oxidation, and corrosion performance of cladding surfaces and their key observations. In addition, the effects of Gas Tungsten Arc Cladding process parameters, the substrate-clad materials combination, microstructural improvements, common advantages, and limitations associated with the technique are also presented. New research and industrial people on weld cladding would benefit from the outcomes of this article.","PeriodicalId":7271,"journal":{"name":"Advanced Materials Research","volume":"2835 1","pages":"113 - 122"},"PeriodicalIF":0.0,"publicationDate":"2022-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86507149","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}

Thermal simulation experiment of titanium matrix composites with different (TiB+TiC) strengthening phase content. The measurement accuracy of material displacement is 0.01 mm. The compression is 70%, and the strain rate is 0.1 mm/s and 0.01 mm/s respectively. Compression tests at different strain rates and temperatures were carried out. The experimental results show that when the (TiB+TiC) 5vol% titanium composite is deformed at 0.01mm/s low strain rate, the peak stresses corresponding to 25°C, 250°C,350 °C and 500°C are increased to 1096MPa, 835MPa, 646MPa and 416MPa respectively. Under the condition of high strain rate of 0.1mm/s, the peak stresses corresponding to 25 °C, 250 °C, 350 °C and 500 °C are increased to 1230 MPa, 896 MPa, 723 MPa and 471 MPa respectively. The deformation law of stress rheological curve is roughly the same, and the high temperature zone has good plastic deformation ability. The titanium matrix composite has high compression rheological mechanical properties and good high-temperature plastic deformation ability. It is the preferred material component for the preparation of titanium matrix composite and powder forging.","PeriodicalId":7271,"journal":{"name":"Advanced Materials Research","volume":"63 1","pages":"101 - 106"},"PeriodicalIF":0.0,"publicationDate":"2022-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79338716","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}

Also within ISIM Timisoara, in addition to the classic FSW welding, processes and methods derived from FSW were also approached. Those processes and methods include friction stir processing (FSP), coatings with functional layers by friction, conventional friction riveting and friction riveting with hybrid effect, hybrid welding methods: TIG assisted friction stir welding FSW-TIG and ultrasonic assisted friction stir welding FSW-US. Recent research were focused on a new method of applying the FSW process, namely friction stir welding in inert gas environment (FSW-IG). Results obtained by ISIM in the field of FSW-IG welding are presented: data / information on solutions for applying inert gas in the welding area, as well as experimental results obtained for FSW-IG welding of DD13 steel, Cu99 copper and AZ31B magnesium alloy respectively. The solutions for providing shielding gas in the welding area were analyzed, verified and validated by experiment. The experimental welding programs generated the necessary data for the development of the FSW-IG welding technologies for the approached materials. By applying FSW-IG welding there was an improvement in the aspect of the welded joints and for some of mechanical characteristics (as the case may be) compared to the application of classic FSW welding. The use of shielding gas also had beneficial effects on the service life of FSW tools.","PeriodicalId":7271,"journal":{"name":"Advanced Materials Research","volume":"26 1","pages":"15 - 24"},"PeriodicalIF":0.0,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73947606","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}

As a result, most of the researches, including the most recent ones, are focused on the morphological analysis of structures eroded under the impact of micro-jets and shock waves, produced by cavitation hydrodynamics. The goal is to create new materials, but also to use new treatment technologies to increase cavitation resistance. As the literature is quite poor in studies related to the materials resistance to cavitation erosion, respectively treatments and technological procedures of it’s improvement, this paper presents the research results on the behavior of vibration cavitation erosion, carried out on three sets of CuZn39Pb3 brass samples, subjected to volumetric heat treatments of hardening for putting in solution at 800°C, followed by tempering at 250°C, 400°C and 600°C. The characterization of the behavior and the cavitation resistance of the structures resulting from the applied heat treatments is performed based on macroscopic images, taken at different representative periods, SEM images at the end of the test duration and values of specific parameters recommended by ASTM G32-2016. The analysis highlights the differences caused by the change in structure by varying the temperature, but also the hardness of the surface exposed to the cavity. Thus, of the three treatments, it is found that the best resistance to cavitation is conferred by the structure resulting from hardening at 800°C, with tempering at 250°C.","PeriodicalId":7271,"journal":{"name":"Advanced Materials Research","volume":"5 1","pages":"1 - 8"},"PeriodicalIF":0.0,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90213635","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}
