evidence at court, that many of the statements denied that they were ever traffic for ready trial. none of them had ever been trafficked. during the investigation mr ramzan was arrested. he had never really met the defendant, had nothing to do with trafficking, had never been alone in a room with errors let alone in a room with errors let alone had sex with her. he described in court is utter consternation at being publicly arrested on the promenades and questioned by the police. i will set out more of the impact of this offending upon him and his family later in his remarks. the defendant set about seeking to back up allegations against mr ramzan and the fictitious traffickers. she did so in a number of ways. i will summarise here only some of them. she manipulated people with whom she was in contact via snapchat to contact her. she would rename these people in her phone with the names of supposed traffickers. she would induce sexual messages from them and take screens ....

york shortly. more on those stories in a moment. let s get more business news. good afternoon. we start in the uk where the first transatlantic flight by a passenger plane powered solely by so called, sustainable aviation fuel , has taken off. the virgin atlantic flight from london to new york currently somewhere over the atlantic ocean is part funded by the uk government. it s running on fuel made from a mixture of sources including crops, household waste and cooking oils. it has a significantly lower emissions lifecycle than traditionaljet fuel and is being billed by the industry as a big tool in hitting net zero targets but a lack of supply is a major stumbling block. we re nowjoined by hannah lawrence, who s a campaigner at stay grounded. hello there to you. many people this morning and in the build up saying it is usually significant. you, however, the organisation refers to carbon, colonisation. it’s however, the organisation refers to carbon, colonisat ....

"A review of challenges and optimization processing during additive man" by Zhijun Qiu, Zhiyang Wang et al.

This article reviews emerging research on additive manufacturing (AM) techniques for the commonly studied trademarked Ni-Cr-based alloys, including Inconel 718, Inconel 625, and Hastelloy X, and also provides a comprehensive overview of challenges in manufacturing processes and optimized processing of deposited parts. Challenges and defects associated with AM of Ni-based components are described, and ameliorated processes for the quality optimization of Ni-Cr-based alloy components are discussed, taking into account both simulation and manufacturing processes. The effects involved by AM processes and optimized operations in mechanical properties of Ni-Cr-based alloys are discussed at the end as well. This paper concludes that the wide application of AM-fabricated Ni-Cr-based alloys still presents many challenges, and these need to be addressed in specific ways for this series of materials, aiming to manipulate their microstructural evolution, segregation, and precipitation. The integra ....

"Crystallographic texture and multiscale boundaries mediated creep anis" by Zhijun Qiu, Hanliang Zhu et al.

The microstructure and high-temperature creep mechanisms of Ni-based Hastelloy C276 superalloy fabricated using wire and arc-based directed energy deposition were investigated systematically and innovatively. The microstructural investigation revealed that the as-fabricated samples comprise γ-Ni matrix and topologically close-packed (TCP) P phase precipitates. The γ matrix subgrains and grains are spread over multiple highly textured columnar dendrites, with a majority of γ <001> crystallographic orientations closely aligned along the deposition direction. Moreover, the interdendritic regions exhibit severe Mo segregation, P phase particles, and dislocation bands. Creep tests were conducted on miniature samples under various temperature and stress conditions, loaded either in the deposition direction (DD) or travel direction (TD). DD samples exhibit lower minimum strain rates, greater strains-to-failure, and longer creep rupture lifetimes than TD samples, indicating significan ....

"The growth behavior and kinetics of intermetallic compounds in Cu–Al i" by Dandan Zhao, Weijia Guo et al.

Due to the low production cost and light weight, copper-clad aluminum conductors show great potential value in the field of power transmission, while the phase structure and organizational changes at the Cu–Al interface in high-temperature environments have a great impact on the electrical and mechanical properties. In this paper, Cu–Al diffusion couples are prepared to study the diffusion process, microstructure, and growth kinetics of intermetallic compounds (IMCs) in Cu–Al interface during heating from 600 °C to 800 °C, and the mechanical and electrical properties of Cu–Al diffusion couples are discussed. The results show that after heat treatment, IMC layers are formed at the Cu–Al interface and the Al-side is composed of CuAl and CuAl2, in which the CuAl phase transforms from long to thick dendrites with the increase of temperature, and finally grows into a “popcorn” form. The IMCs at the Cu–Al interface from the Cu side to the Al side are in the order of Cu3Al l ....
