Influence of Ni and PWHT on microstructure evolution and mechanical properties of GTA-welded duplex stainless steel and super duplex stainless steel joints: A comparative investigation
No full textIn the present investigation, a new endeavor has been made to analyze the impact of the secondary process (post-weld heat treatment (PWHT)) as well as Ni addition on the microstructure and mechanical characteristics of welds. Welds between similar joining materials from duplex stainless steels (DSS), as well as super DSS (SDSS), were made by the gas tungsten arc welding (GTAW) process. For DSS, after PWHT with the addition of Ni element, the amount of austenite rises and becomes more uniformly distributed with curved boundaries, while for SDSS, the microstructure mainly consists of intergranular and Widmanstätten austenite. According to the comparison of phase percentages obtained based on both ASTM E1245 and ASTM E562, a good balance between ferrite and austenite phases of joint materials was achieved. X-ray diffraction analyses on both joints revealed that phases are mainly ferrite and austenite with different lattice parameters without evidence of unwanted intermetallic phases. The addition of Ni increases the hardness values of DSS weld metal compared to the base metal due to an increased amount of Widmanstätten austenite and ferrite in the microstructure. The lowest ductility was obtained for the SDSS weld sample with the addition of Ni and PWHT because of the existence of secondary austenite in the weld metal and the Widmanstätten morphology of the austenite. The effect of PWHT on the development of microstructure and mechanical behaviors was more than the effect of nickel powder on weld samples. © IMechE 2024
Hierarchical Representations of Freebase Topics
No full textThe dataset contains more than 21M hierarchical relationships about ≈10M topics extracted from Freebase knowledgebase. The topics span the various categories of Freebase including Science & Technology, Arts & Entertainment, Sports, Society, Products & Services, Transportation, Time & Space, Special Interests, and Commons. The relationships describe the hierarchies of topics in terms of Types, Domains, and Categories. For example, ‘Albert Einstein’ can be found as a topic that is a sub-class of ‘Person’, belonging to the ‘People’ domain and ‘Society’ category. Another entity named as ‘Albert Einstein’ can also be found as a sub-class of ‘Book’, belonging to the ‘Books’ domain and ‘Arts & Entertainment’ category. The dataset is published in JSON and CSV formats, sample files are provided to help explore how the dataset is structured. The dataset is believed to be useful for studying the inter-related connections among topics in different domains of knowledge.

The Role of Nitrogen Gas and PWHT on Pitting Corrosion Behavior of Duplex Stainless‐Steel Joint Made by GTAW
No full textThe influence of nitrogen gas and post-weld heat treatment (PWHT) on microstructure and pitting corrosion
ehaviors of duplex stainless steel welds were investigated. After gas tungsten arc welding process, the microstructure of the weld zone included grain boundary austenite, Widmanstatten austenite which forms on the grain boundary austenite, and intergranular austenite. With application of PWHT process, intergranular austenite grew to reach a spheroidal shape which was uniformly distributed in the matrix. Precipitation of chromium nitride in the ferrite phase was observed in grain boundaries and inside the ferrite phase with addition of nitrogen. By application of PWHT, the value of pitting potential increased and additionally corrosion resistance improved as nitrogen gas was applied. Due to higher pitting resistance equivalent number (PREN value) of austenite in regard with ferrite, ferrite as a weaker phase plays a prominent role in predicting the pitting corrosion resistance.The influence of nitrogen gas and post-weld heat treatment (PWHT) on microstructure and pitting corrosion behaviors of duplex stainless steel welds were investigated.

Rupture in intergenerational relationships and its effects on identity formation in children of Iranian family
No full textOne of the fields of developmental clinical psychology is understanding how culture impacts development, behavior, and disorder. Spreading of industrialization has changed traditional communities in the sociocultural context. Many of these changes are impressed by the differences of generations which substitute each other. Identity is related to sociocultural context. This study, which is intercultural, aims to trace sociocultural rupture in intergenerational relationships and to survey its role on identity formation. In this study, two qualitative methods have been compounded. Tracing of sociocultural rupture between subjects and their parents has been used for opening a way to survey identity. So, in the beginning, according to interviews by "grounded theory", We have provided issues related to sociocultural relationships. Then on this basis, by using the clinical method, identity components have been studied as a case study. 10 young girls and women have been selected in Tehran on the based of "theoretical sampling" method. Research tools were the interviews directory. Data analysis have been done with data coding and interpretation. The results of this study have drawn as the theoretical model and they have shown that more intensity of the sociocultural rupture between two generation, less probability of the identity achievement in children of family
Gaya Bahasa dalam Puisi Aḥinnu ilá Khubzi Ummī Karya Mahmoud Darwish
No full textLiterature is an art mediated by language, while literary works are a product of imagination with the medium of language. A poem is a literary work that has a dense language of figures and symbols. Therefore, research is needed to analyse the meaning of a poem. One of the analyses of poem research is using stylistic analysis. The poem that is the object of this study is the poem Aḥinnu ilá Khubzi Ummī by Mahmoud Darwish.
