Abstract A novel AZ91 Ce containing magnesium alloy characterized by excellent corrosion resistance is fabricated adding rare earth (cerium) in the form of a Mg‐Ce master alloy. The metallographic investigation shows that added to can obviously decrease size β‐Mg 17 Al 12 and forms 11 3 intermetallic compounds shape fine needles. tests electrochemical measurements indicate higher than AZ91. Furthermore, increasing content further enhance resistance. X‐ray photoelectron spectroscopy (XPS)...
We present an overview of the state-of-the-art RF/Analog foundry technology as well future trends and roadmap. This set RF/analog is built on top cutting-edge logic platforms it enables cost-effective fast-time-to-market/volume system-on-chip (SoC) applications, including rapidly growing wireless-LAN (WLAN) Blue tooth products in addition to traditional consumer communication products. Results from 0.18 /spl mu/m- 0.13 mu/m-generation mixed-signal RF CMOS technology, SiGe BiCMOS are...
Hastelloy N alloy is an excellent oxidation and corrosion-resistant material, which selected as the shell material for main vessel of molten salt reactors (MSRs). In this work, we conducted double-sided gas tungsten arc welding (GTAW) on 4 mm thick plates to examine microstructure mechanical properties welded joints. The S-N curve was obtained by fatigue test. experimental results show that cracks initiate along weld toe propagate inward in a fan-shaped pattern. hardness highest...
To achieve low‐stress and small‐deformation welding of thin‐walled structures for the fourth‐generation nuclear power plants, GH3535 superalloy is welded to itself using electron beam (EBW). The microstructure mechanical properties joints are characterized by scanning microscopy (SEM), energy dispersive spectrometer (EDS), hardness, tensile tests. A macro‐defect‐free joint could be obtained 22 mA current under 65 kV voltage with 300 mm min −1 speed. Different sub‐grain solidification...
Micro-arc oxidation (MAO) is very effective to enhance the corrosion performance of Mg alloys. However, micro-pores in MAO coatings provide a channel for medium reach alloy matrix. In this work, electron beam strengthening (EBS) performed improve microstructure and coating prepared subsequently performance. The crystalline size decreases, roughness improves, resistance increases. Furthermore, refinement grain by EBS improves discharge MAO. noticeable effect on lies improvement density, such...
