چکیده
This article describes the oxidation resistance of laser beam welds made from E110 zirconium alloy with a chromium coating obtained using multi-cathode magnetron sputtering. Oxidation tests welded Zr without and Cr were performed in an air atmosphere at 1100 °C for 2–90 min. Then, analysis their cross-section microstructure different regions (weld, heat-affected, bulk zones) was done optical microscopy. Hardness measurements three-point bending demonstrated hardening Cr-coated after that is discussed article. Brittle fracture behavior observed uncoated weld even short period high-temperature oxidation.

' * , sy Solidification Behavior and Structure of AI - Cu Alloy Welds
The microsegregation behavior of electron beam (EB, and gas tungsten arc (GTA) welds of Al-Cu alloys covering a range from 0.19 to 7.74 wt% Cu were characterized for dendrite core concentrations and fraction eutectic solidification. Although a single weld speed of 12.7 mm/sec was used, some differences were observed in the segregation behavior of the two weld types. The microsegregation behavio...
متن کاملThermo-mechanical behavior of shape memory alloy made stent- graft by multi-plane model
Constitutive law for shape-memory alloys subjected to multi-axial loading, which is based on a semi-micromechanical integrated multi-plane model capable of internal mechanism observations, is generally not available in the literature. The presented numerical results show significant variations in the mechanical response along the multi loading axes. These are attributed to changes in the marten...

PURPOSE The mechanical and interfacial characterization of laser welded Co-Cr alloy with two different joint designs. MATERIALS AND METHODS Dumbbell cast specimens (n=30) were divided into 3 groups (R, I, K, n=10). Group R consisted of intact specimens, group I of specimens sectioned with a straight cut, and group K of specimens with a 45° bevel made at the one welding edge. The microstructur...
متن کاملOxidation resistance of graphene-coated Cu and Cu/Ni alloy.
The ability to protect refined metals from reactive environments is vital to many industrial and academic applications. Current solutions, however, typically introduce several negative effects, including increased thickness and changes in the metal physical properties. In this paper, we demonstrate for the first time the ability of graphene films grown by chemical vapor deposition to protect th...

The purpose of present research was production ofZr-based alloy as the nuclear fuel cladding by mechanical alloying (MA) and sintering process. Firstly, Zr and Cr powders were mechanically alloyed to produce the refractory and hard Zr-10 wt% Cr alloy, and then, the powder mixtures were consolidated by press and following sintering at temperature of 800˚C min. The phase evolution, microstructura...
