After the treatment, the samples were subjected to 3-point bend fatigue test. Due to the newly introduced residual stresses, the high cycle fatigue performance of the alloy after the treatment was improved over the whole range of loading stresses, ranging from 17% improvement for the highest loading stress up to 66% improvement for the lowest loading stress.<\/p>\n","oddelovace":"none"},{"acf_fc_layout":"obrazek","obrazek":{"ID":7485,"id":7485,"title":"3point_bend","filename":"3point_bend.jpg","filesize":6217825,"url":"https:\/\/www.hilase.cz\/wp-content\/uploads\/3point_bend.jpg","link":"https:\/\/www.hilase.cz\/uspechy\/lsp-technologie-muze-pomoci-pri-zvyseni-zivotnosti-jadernych-reaktoru\/3point_bend\/","alt":"","author":"15","description":"","caption":"","name":"3point_bend","status":"inherit","uploaded_to":7484,"date":"2019-07-23 07:47:35","modified":"2019-07-23 07:47:35","menu_order":0,"mime_type":"image\/jpeg","type":"image","subtype":"jpeg","icon":"https:\/\/www.hilase.cz\/wp-includes\/images\/media\/default.png","width":4608,"height":3456,"sizes":{"thumbnail":"https:\/\/www.hilase.cz\/wp-content\/uploads\/3point_bend-175x175.jpg","thumbnail-width":175,"thumbnail-height":175,"medium":"https:\/\/www.hilase.cz\/wp-content\/uploads\/3point_bend-600x450.jpg","medium-width":600,"medium-height":450,"medium_large":"https:\/\/www.hilase.cz\/wp-content\/uploads\/3point_bend-768x576.jpg","medium_large-width":768,"medium_large-height":576,"large":"https:\/\/www.hilase.cz\/wp-content\/uploads\/3point_bend-1800x1350.jpg","large-width":1800,"large-height":1350,"1536x1536":"https:\/\/www.hilase.cz\/wp-content\/uploads\/3point_bend.jpg","1536x1536-width":1536,"1536x1536-height":1152,"2048x2048":"https:\/\/www.hilase.cz\/wp-content\/uploads\/3point_bend.jpg","2048x2048-width":2048,"2048x2048-height":1536,"image":"https:\/\/www.hilase.cz\/wp-content\/uploads\/3point_bend-1170x484.jpg","image-width":1170,"image-height":484,"gallery":"https:\/\/www.hilase.cz\/wp-content\/uploads\/3point_bend-273x210.jpg","gallery-width":273,"gallery-height":210,"card":"https:\/\/www.hilase.cz\/wp-content\/uploads\/3point_bend-740x390.jpg","card-width":740,"card-height":390,"square":"https:\/\/www.hilase.cz\/wp-content\/uploads\/3point_bend-360x360.jpg","square-width":360,"square-height":360}},"popis":"","centrovat_popis":[]}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.9 -
