A new nondestructive test method of three-step phase-shifting correlation speckle pattern interferometry to study the dynamic loads of structural materials is proposed. In this method three speckle interferograms (SIs) of the specimen surface, differing only by arbitrary unknown phase shifts, are recorded before the loading and one SI is recorded under the dynamic load. The surface displacement field under dynamic loading is determined using the obtained SIs. Two algorithms for the implementation of the method are proposed. They use an integrating bucket technique to record SIs and make it possible to determine the phase maps of the surface displacement fields at any moment of applying the dynamic load. We can use this method to produce a temporal sequence of surface displacement fields during loading.</p>","PeriodicalId":18230,"journal":{"name":"Materials Science","volume":"35 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140098119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Models were based on quadratic regressions with first order partial derivatives and on polynomials with a reduced number of signs. By applying mathematical models, it was established that the pitting resistance of these steels increases with an increase in the average distance between oxides, the average diameter of austenite grain, specific magnetic susceptibility, the decrease in the volume of δ-ferrite and the number of the smallest oxides up to 1.98 μm in size. The positive effect of Cr and Mn on the pitting resistance of the studied steels was studied. Probably this occurred due to the increase of the solubility of N in austenite, reduction of the Fe atoms diffusion intensity to the surface of stable pittings and the increase of Cr to metastable pittings, contributing to their repassivation, which increased the pitting resistance of steels.

However, forming of components influences the microstructure and can thus change the corrosion resistance of the steel. In this context, the corrosion rate of the steel 316L is determined for the case of uniform corrosion of various cold-rolled conditions by ageing tests in 0.5 M H<sub>2</sub>SO<sub>4</sub>. The microstrain, the martensite fraction, and the residual stress state are quantified using X-ray diffraction. The surface roughness is measured by laser scanning microscopy. Three different model equations are derived by means of multiple regression to predict the corrosion rate as a function of the specimen properties. The analysis shows that a particularly simple model equation, which predicts the corrosion rate only via the plastic strain, shows insufficiently large deviations from the experimentally determined corrosion rates. However, a low divergence to the experimental results with a mean deviation of less than 4% is achieved by using a model equation that takes microstructural parameters and the surface ratio into account. Within this model equation, an increased corrosion rate is achieved with higher microstrain and residual compressive stress of the austenite phase as well as a higher surface-area ratio. A higher fraction of martensite is found to lower the corrosion rate.</p>","PeriodicalId":18230,"journal":{"name":"Materials Science","volume":"5 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139755925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
