Misorientation of the specimens was calculated by Kernel Average Misorientation (KAM), Grain Average Misorientation (GAM) and Grain Orientation Spread (GOS). The values calculated by KAM, GAM and GOS increased with the strain increasing linearly during the transient creep stage. The tendency corresponded to the changes in total dislocation density estimated by Transmission Electron Microscopy (TEM). In the transient creep stage, good linearity between geometrically necessary (GN) dislocation estimated from KAM values and dislocation density by TEM was revealed. Compared the increments among misorientations calculated by KAM, GAM and GOS, one of GOS was the highest and the others were almost the same. Increments of KAM values were lower than those reported in the previous papers. Because data was obtained from the crept specimens in this study but data were obtained from specimens deformed in room temperature or moderate temperature. It was suggested that the increment of GN dislocation become lower due to dynamic recovery during creep test in this study. When the pitches in the EBSD measurement were taken account into, the increment of GAM values in this study was equal to one reported in the previous paper where the data was obtained from the crept specimens of stainless steel with the similar grain size.","PeriodicalId":17366,"journal":{"name":"journal of the Japan Society for Testing Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77775457","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}

Firstly, the stress distribution within cylinders with various lengths is analyzed by the three dimensional Finite Element Method. Then the formula is proposed based on the analyzed results for the four-point bending (Four-point bending test of the beam having a rectangular cross section, FPB r ) test and the three-point bending (Three-point bending test of the beam having a rectangular cross section, TPB r ) test of ASTM, JIS by the use of the beam having a rectangular cross section and the FPB c and TPB c tests. The specimen with 5-10cm in diameter and 10-20cm in length is used in the FPB c and TPB c tests. This dimension is that used in uniaxial compression test of concrete or rock drilled core. Secondly, a series of the FPB and TPB tests by use of both type of specimen is performed by the use of granite specimen with various lengths, then it is shown that the flexural strength is evaluated by the proposed formula and compared with that by the conventional one. Finally, it is made clear that the suggested three-point bending (TPB c ) by use of the cylinder typed specimen is available for evaluating the flexural strength of concrete and rock easily. beam having a rectangular cross section, and the FPB c and TPB c tests.

The CWAs were electric porcelain insulator wastes supplied from an electric power company, which were crushed and ground to fine aggregate sizes. In this study, to further develop the CWA mortar as an eco-efficient, ground granulated blast-furnace slag (GGBS) was incorporated. The GGBS was utilized as a supplementary cementitious material (SCM) at three different replacement levels of 15, 30, and 45% by weight of cement. The time dependency of the GGBS on enhancing chloride resistance in the CWA mortars was experimentally assessed by using an electron probe microanalysis (EPMA). The tests were carried out on mortar samples after immersion in 5.0% NaCl solution for 24, 48, and 96 weeks. Another set of the mortar samples was exposed to a laboratory ambient condition for 24, 48, and 96 weeks and then followed with a carbonation test. The resistance to the chloride ingress of the CWA mortar becomes more effective in proportion to the replacement level of the GGBS. Meanwhile, the carbonation depth of the CWA mortar increases with increasing the GGBS. The relationship between the apparent chloride diffusion coefficient and the GGBS replacement level was shown along with the immersion time.","PeriodicalId":17366,"journal":{"name":"journal of the Japan Society for Testing Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83844137","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 study, the behavior of humidity in wooden sheathed wall of housing outer wall was considered. The humidity, which was observed in the walls, was compared with non-destructive inspection data, the temperature and the humidity observed inside and outside of the wall. Non-destructive inspection data was (cid:3) classified and inspected according to their observed position, their specification and environment. As a result, the boundary of the humidity in the wall, which has effect on the housing deterioration, was estimated from 64% to 67%. The reliability of non-destructive inspection method was indicated by Bayes method, therefore the humidity inspection with electrical resistance devices is more reliable than the inspection with high frequency devices. With the electrical resistance devices, the non-destructive inspection on lower position mortar wall is useful on the humidity inspection in wooden sheathed walls. The humidity in the wall is affected by the environment, specification and the observed position.","PeriodicalId":17366,"journal":{"name":"journal of the Japan Society for Testing Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78957497","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}
