The dynamic tensile mechanical properties of 18Ni350 maraging steel (M350) fabricated by wire arc additive manufacturing (WAAM) was investigated the split Hopkinson bar (SHTB) and microstructural analysis. results show that yield stress (YS) M350 samples, both in as-built heat-treated state, increases firstly then decreases with increasing strain rate. YS sample reaches maximum value 2195MPa at 1230s-1, to 3395MPa after heat treatment, due precipitation intermetallic. Compared horizonal...
The continuous mutation of severe acute respiratory syndrome coronavirus 2 has made the disease 2019 (COVID-19) pandemic complicated to predict and posed a challenge Beijing 2022 Winter Olympics Paralympics held in February March 2022. During preparations for Olympics, we established dynamic model with pulse detection isolation effect evaluate epidemic prevention control measures such as entry policies, contact reduction, nucleic acid testing, tracking, isolation, health monitoring...
The Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spreads rapidly and insidiously. Coronavirus disease 2019 (COVID-19) screening is an important means blocking community transmission in China, but the costs associated with testing are high. Quarantine capacity medical resources also threatened. Therefore, we aimed to evaluate different strategies balance outbreak control consumption resources. A network 2000 people, considering heterogeneities household size...
Abstract Understanding the intercity poultry trading network is crucial for assessing risk of avian influenza prevalence. Unfortunately, in China has rarely been described. Here, with a modified radiation model, we obtain values proxy variable trade flows among 318 prefecture-level cities 2015 utilizing product capacity and demand quantity cities. The results are validated by comparing volumes investigated literature, it found that model can accurately predict main This first dataset on...
Ti6Al4V-x wt.%TiB2 titanium matrix composites (x=0, 0.01, 1, 3.4, 4.8) were prepared by selective laser melting (SLM), followed solution-aging treatment. The microstructure and mechanical properties of the SLM-formed samples heat-treated ones systematically investigated. In samples, in-situ TiB whiskers clustered around original position TiB2 particles, which reacted with through dissolution. morphology distribution could be explained established transformation model microstructure. phase...
The 18Ni350 maraging steel (M350) bulk was fabricated by wire arc additive manufacturing (WAAM). heat treatment process of solution at 1000℃ for 1 hour and aging 490℃ 6 hours selected, then the split Hopkinson tensile bar (SHTB) employed dynamic test. Three tests with different strain rates were carried out as-built heat-treated samples in horizontal vertical directions. After impact loading applied to sample, it found that yield stress (YS) sample firstly increased decreased rate, direction...
