Long-term creep deformation behavior of the pressure-bearing structures made of titanium alloys under alternating compressive stress has a direct impact on the structural stability. The compressive creep evaluations of Ti-6Al-4V ELI alloys with basketweave microstructure under alternating stresses have been carried out by a uniaxial compressive creep tester. The compressive creep deformations have strong stress sensitivity due to the larger creep strain by the higher applied compressive stress. The dislocation densities in α and β phases increase with the increase of applied compressive stresses. The dislocation slip and dislocation multiplication occur in α phases accompanying with high dislocations density in β phases caused by compressive deformation. The large strain concentration occurs at the grain boundaries of α/β phase due to dislocation plug after creep, which causes the grain boundary pinning. The compressive creep deformation of Ti-6Al-4V ELI alloys under alternating stress is a decelerating creep process and controlled by dislocation slip. The slight refinements of the grains and hardening have been confirmed after creeps. The synergistic effects of dislocation multiplication, grain boundary pinning and grain refinements lead to strengthening the Ti-6Al-4V ELI alloys and decelerating the compressive creeps.","PeriodicalId":49875,"journal":{"name":"Materials Science-Poland","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43273773","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}

The study was carried out to accurately predict the residual stress distribution of carburized samples after the quenching process. The stress and retained-austenite amount were measured via X-ray diffraction. Similarly, the carbon content was determined using a carbon sulfur analyzer, respectively. A detailed model with the coupling of thermal, metallic, and mechanical fields was built to predict the evolution of the stress field during the quenching process. The carburized “thoroughly” specimens at different carbon potentials were used to obtain the required mechanical property parameters and dilatometric parameters for FEM simulation. According to the results, the martensite transformation kinetic parameters α value of 18CrNiMo7-6 alloy steel should be 0.0202. With the increase of carbon content, the changing trend of the transformation plasticity coefficient K appeared as a 'tick' shape. A compressive residual stress field was generated at the carburized layer surface after the quenching process, and the maximum value of 340 MPa occurred at ~ 0.9 mm below the surface. The carbon profile and residual stress fields predicted from the FEM simulation corresponded closely to the experimentally determined results.","PeriodicalId":49875,"journal":{"name":"Materials Science-Poland","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43294957","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}

Combinatorial effects of initial gas-atomized powder sizes on microstructure and corrosion properties of SLM-ed Ti-6Al-4V alloys have been investigated by optical microscopy, X-ray diffraction, electrochemical measurements and surface free energy. The SLM-ed Ti-6Al-4V alloys are composed of acicular α' martensite and α phases. Many pinhole defects and twin boundaries exist in the SLM-ed Ti-6Al-4V alloys. According to electrochemical tests and surface free energy calculation, the SLM-ed Ti-6Al-4V alloys with 0 – 53 μm powders have the most positive corrosion potential, the lowest current density and the smallest surface free energy of 20.89 mJ m2. The passive film of SLM-ed Ti-6Al-4V alloys with 0 – 53 μm powders has superior protection ability due to their large thickness. The carrier concentration of SLM-ed Ti-6Al-4V alloys with 0 – 53 μm powders is the lowest by the Mott-Schottky curves. The SLM-ed samples with contact angles higher than 90º are hydrophobic, but the small contact angle of 46.98º reflects the hydrophilic features of as-rolled Ti-6Al-4V alloys. The combinatorial recipe of SLM-ed Ti-6Al-4V alloys with 0 – 53 μm powders is optimal for improvements on the corrosion resistance.","PeriodicalId":49875,"journal":{"name":"Materials Science-Poland","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47534033","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}

However, a large number of paper cultural relics are suffering from aging, mildew, yellowing, cracks, embrittlement and other threats, or are even completely damaged. To enhance the strength of paper cultural relics and prolong the life of paper cultural relics, a novel CMC-acrylate-OVPOSS graft copolymer was synthesized with carboxymethyl cellulose (CMC), methyl methacrylate (MMA), butyl acrylate (BA), hydroxyethyl methacrylate (HEMA), glycidyl methacrylate (GMA), octavinyl polyhedral oligomeric silsesquioxane (OVPOSS). The synthesized materials were analyzed by infrared spectroscopy, X-ray diffractometer, thermal analyzer and X-ray photoelectron spectroscopy. In addition, the reinforcement solution was coated on the surface of the paper, and the protective effect of the reinforcement solution on the paper was evaluated by testing the mechanical and optical properties of the paper. When the reinforcement solution with a mass concentration of 10 % was coated on the paper, the mechanical properties of the paper were greatly improved, and the gloss and whiteness were basically unchanged.","PeriodicalId":49875,"journal":{"name":"Materials Science-Poland","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42429516","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}
