This study presents a systematic of multilayered steel-steel composites prepared via laser powder bed fusion (L-PBF) in an open-architecture additive manufacturing system equipped with multiple delivery module. Stainless steel AISI 316 L and high‑carbon stainless 440C were chosen as the model material system. The printed samples characterized using optical microscopy, X-ray diffraction, electron backscattered energy-dispersive spectroscopy, tomography, micro-hardness to understand complex...
Summary Telbivudine, an FDA pregnancy category B drug, has been found to reduce hepatitis virus (HBV) perinatal transmission with no safety concerns in infants aged up 1 year. This study evaluated the long‐term efficacy and of telbivudine 214 born 210 pregnant women chronic infection who were treated during (weeks 20‐32 gestation). The followed for 5 years after birth. endpoint was rate transmission, which established by HBsAg HBV DNA levels at 7 12 months. Safety endpoints included head...
Nowadays, a good corrosion resistance of lightweight steel is demanded for its application. However, due to the high contents Mn and C, which are always corrosion-susceptible elements in steels, conventional not desirable this mission. Although Cr widely believed be common alloying element improve most it considered ineligible using relatively content C. This because trade-off between mechanical properties by Cr. In recent years, rapid developments additive coating manufacturing have...
To obtain both ultra-high strength and good ductility in pearlitic steel wires, a new processing technique was proposed following the principle of inherited texture. Microstructure evolution wires investigated by FE-SEM, EBSD TEM, while mechanical properties were determined tensile torsional tests. Two types with different ferrite <110> texture intensity obtained varying pre-drawing strain. The orientation between drawing direction exhibited great effect on deformation behaviour...
Dislocation structures can be directly related to the fatigue properties of metals, such as strength, including limit and saturation stress. We present an indirect dislocation-structure-based method evaluate local stresses for in-depth analysis sleeper screw failures, there is little knowledge about load these failures. The screw, fastening baseplates rails sleepers, a small but critical component in railway. High loads from passing trains are transferred screws, leading cyclic straining. In...
Effects of vanadium micro-alloying on the microstructure and material properties pearlitic steel were investigated, in an effort to obtain higher strength wire with good thermal stability. Experimental results showed that V element mainly existed cementite acted strengthen within wire. Consequently, adding improved tensile plasticity initial rods. In addition, additions increased work hardening rate wires during cold drawing process. Moreover, addition fragmentation drawing, because presence...
