    Laser directed energy deposition additive manufacturing using friction stir channelling extruded wire

    No full text
    This paper investigates a new ‘forged’ wire additive manufacturing processing, in which the metal wire is produced as a by-product from stationary shoulder friction stir channelling (SS-FSC) under the severe plastic deformation mechanism (known as CoreFlow®), and then used as the feedstock in directed energy deposition with a laser beam and wire feedstock (DED-LB/w) additive manufacturing. For the first time, the ‘by-products’ produced in the SS-FSC process, which are ‘forged’ 6082 aluminium alloy wire, were tested with built-tracks using DED-LB/w. Process mapping was built to demarcate the melting states, including the stable, dripping, and incomplete melting regimes, over a wide range of laser energy densities (92 to 303 kJ·s·g−1·cm−2). Metallurgy tests were also conducted to reveal the evolution of the microstructure and defect formation of the deposited tracks. It was found that: (i) Stable deposition with a grain size of 9−20μm can be achieved with optimised processing parameters, i.e., energy density 243kJ·s·g−1·cm−2 with a laser power 3.8kW, a scanning speed 0.8cm·s−1 and a wire feed rate 2.0cm·s−1; (ii) The substructure morphology is gradually transitioned from columnar at the track bottom to cellular (8.9±1.8μm) at the top, driven by an increased cooling rate; and (iii) The built track porosity is mainly composed of gas pores that are small (equivalent diameter of 20−50μm) and spherical, primarily resulting from the ambient gas, the SS-FSC extruded wire oxides and contaminations. The study supports resource-efficient, low-carbon manufacturing via reuse of by-products, in alignment with the Net Zero Strategy.</p

    Thermodynamic insights into the oxidation mechanisms of CrMnFeCoNi high-entropy alloy using in situ x-ray diffraction

    No full text
    This paper utilizes in situ X-ray diffraction (XRD) to investigate the high-temperature oxidation behaviour of CrMnFeCoNi high-entropy alloy (HEA). We found that (1) Mn is the major oxide-forming element in both vacuum and air environments, leading to the formation of non-protective oxides that deplete the bulk alloy of Mn; (2) no oxides like Cr2O3, Fe2O3, or Fe3O4 were observed during the high-temperature oxidation behaviour of CrMnFeCoNi, which contradicts some previous studies on the isothermal oxidation of CrMnFeCoNi HEA. We also analysed and compared the experimental results with thermodynamic calculations by using ThermoCalc version 2022b software following the CALPHAD method. ThermoCalc predicted spinel oxide in a vacuum environment, along with halite oxides observed in experimental results; also, in an atmospheric environment, it predicted only spinel, indicating the need for further investigation into factors to validate the thermodynamic predictions. Our study shows that the in situ HTXRD technique is a powerful tool to accurately identify time–temperature-dependent phase formation/transformation for studying oxidation behaviours and understanding oxidation mechanisms in HEAs.</p

The female holotype was collected from Yulongxueshan whilst the male paratypes were collected from Ludian, thus the association of male and female requires a confirmation from more material. In a recent expedition made by the first author, specimens of both sexes were collected from both localities. An examination of male and female genitalia proved the original association of male and female to be correct. Distribution.

    When Top-Down Meets Bottom-Up: Local Adoption of Social Policy Reform in China

    No full text
    Authoritarian local leaders face two driving forces in social policy making: top-down pressures from the regime and bottom-up motivations derived from local conditions. Existing studies recognize the importance of both forces but remain unclear as to how they interact and which of them is more influential in driving local policy adoption. Focusing on two health insurance integration policies in China, we find that when the policy is political (i.e., entailing substantial class conflicts and bureaucratic friction), top-down pressure for compliance is a dominant driver for local adoption of social policy reform. When the policy is less political, bottom-up motivations based on local economic geography together with top-down pressure drive local adoption. We find support for this argument from an analysis of an original city-level dataset on social health insurance in China from 2004 to 2016. This study has implications for distributive politics, decentralization and government responsiveness in authoritarian countries.Peer reviewe

    Does social insurance enrollment improve citizen assessment of local government performance? Evidence from China

    No full text
    Although many studies claim that social policies are “carrots” that authoritarian leaders use to garner public support, the assumption that social benefits can boost public support of government has been rarely tested empirically, especially at the local levels. This article investigates the effects of social insurance enrollment on citizens' assessment of local government performance using data from the 2010 China Family Panel Study. We use propensity score matching to reduce selection bias and ordered probit regressions with fixed effects to examine these possible effects. We find that social insurance enrollment had a significant positive effect on rural citizens' assessment of government performance, but this effect did not exist for their urban and migrant peers. This discrepancy could be largely due to the groups' different expectations for government redistribution and their distinct experiences of China's social welfare reform. We conclude that the Chinese authoritarian government has achieved partial success in its attempt to use socialpolicies to maintain popular support.Peer reviewe

    Impact of urban-rural health insurance integration on health care: evidence from rural China

    No full text
    In recent years, Chinese local governments have experimented with integrating the social health insurance system segmented between rural and urban areas to unify the administration, policy, and funds of various health insurance programs. In this study, we take advantage of the staggered implementation of the urban-rural health insurance integration across cities over time to examine the impacts of the integration on rural residents’ health care utilization and health outcomes. Based on an original city-year level policy dataset and the China Health and Retirement Longitudinal Study (CHARLS) for the years 2011, 2013, and 2015, we find that the integration significantly increases the middle-aged and older rural residents’ inpatient care utilization and this positive effect is particularly salient in poor areas. Moreover, we find that the positive policy effect of integration is attributed to enhanced health insurance benefits, such as a higher reimbursement rate for inpatient care. However, the integration has limited impacts on the middle-aged and older rural residents’ health outcomes. This study reveals the partial success of urban-rural health insurance integration to reduce health care inequality in China.Please replace the old version using this updated one.Peer reviewe
