The shape memory effects and corrosion properties are significantly influenced by additives and heat treatments. Vacuum arc remelting was employed to prepare Fe-10Mn-6Si-4Ni-7Cr-0.3C-mTi/nNb (m = 0.1, 0.3, 0.5, 0.7, n = 0.05, 0.1, 0.3, 0.5) shape memory alloys. The samples were hot-rolled at 1100°C and solution heat-treated at 1150°C for 1 h. The shape memory effect, microstructure, and corrosion performance of Fe-10Mn-6Si-4Ni-7Cr-0.3C-mTi/nNb were analyzed at higher aging temperatures. The microstructural investigations indicate that large amounts of TiC, NbC, Cr23C6, and Cr7C3 phases are precipitated when aged at 800°C, leading to improvement of the shape memory effect of the alloys. The shape recovery ratio reaches 89.9%, 89.5%, 91.1%, and 74.4% for the alloys with 0.1 Ti, 0.3 Ti, 0.5 Ti, and 0.7Ti additions, respectively, at 800°C aging temperature under 3% bending strain. The aging at 500°C increased the shape memory effect by 20–30%, while further aging at 700°C only improved it by a further 10–20%. The shape recovery ratio of alloys with 0.05 Nb and 0.1 Nb reached a maximum of 88.6% and 88.4%, respectively, when aged at 900°C, while, when aged at 800°C, 0.3 Nb and 0.5 Nb reached 83.7%, and 82.9%, respectively. The shape recovery ratio of the alloys with Nb was increased by about 5–30% compared to that with no Nb. The addition of Ti/nNb and aging at higher temperatures improved the corrosion resistance in 3.5-wt.% NaCl solution owing to the formation of Ti/Nb carbide more easily than Cr carbide, leaving a higher content of Cr in the matrix of the alloys.</div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"76 11","pages":"6680 - 6691"},"PeriodicalIF":2.1,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142225738","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}

Furthermore, the harmonic response analysis indicated that the maximum stress at the clamped side is of about 344 MPa in the gradient bar actuator under voltage of 220 V at the resonance condition, revealing 12% reduction relative to the bulk bar actuators.

Therefore, in this paper, the Cu/AZ31/Cu multilayered composite has been fabricated by the cross-accumulative single-pass rolling method and the state-of-art process of cross-accumulative double-pass rolling. After each pass in these methods, the rolling direction was rotated anticlockwise. According to SEM images, all the layers were perfectly bonded without any obvious imperfections due to applying large strain and strain-path changes. Moreover, by increasing the cycles, the plastic instabilities increased in composites, although the ADPR method resulted in a more uniform reduction in AZ31 layer thickness and distribution of broken layers in the matrix. The line EDS analyses carried out on the interfaces of Cu/AZ31 did not show any interphases during the two methods. Furthermore, based on EBSD and TEM images, the grains were refined by both methods at higher cycles, although finer grains in Cu and AZ31 layers were obtained by the ADPR method. In addition, by increasing the cycles, the strength and hardness values of the composites increased. The composites processed by the ADPR process showed a tensile strength of 409 MPa and elongation of 17% which were higher than those achieved by the ASPR process. Similarly, the measured hardness of 213 HV (Cu) and 109 HV (AZ31) were achieved by the ADPR process, while lower values of the hardness of 209 HV (Cu) and 105 HV (AZ31) were achieved by the ASPR process.</div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"76 10","pages":"6017 - 6026"},"PeriodicalIF":2.1,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199424","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}
