“…Zirconium powders can be produced using various methods: electrochemical, reduction, atomization, hydrogenation (hydrogenation/dehydrogenation (HDH)). The HDH method is used most often; however, zirconium powders have an irregular shape [1]. Contamination of zirconium powders by air (more specifically oxygen) and hydrogen is thus a problem during sintering [5].…”

Zr-2.5Cu and Zr-10Cu powder mixtures were consolidated in the extrusion process and using the spark plasma sintering technique. In these studies, material tests were carried out in the fields of phase composition, microstructure, hardness and tensile strength for Zr-Cu materials at room temperature (RT) and 400 °C. Fractography analysis of materials at room temperature and 400 °C was carried out. The research took into account the anisotropy of the materials obtained in the extrusion process. For the nonequilibrium SPS process, ZrCu2 and Cu10Zr7 intermetallic compounds formed in the material at sintering temperature. Extruded materials were composed mainly of α-Zr and ZrCu2. The presence of intermetallic compounds affected the reduction in the strength properties of the tested materials. The highest strength value of 205 MPa was obtained for the extruded Zr-2.5Cu, for which the samples were cut in the direction of extrusion. For materials with 10 wt.% copper, more participation of the intermetallic phase was formed, which lowered the mechanical properties of the obtained materials. In addition to brittle intermetallic phases, the materials were characterized by residual porosity, which also reduced the strength properties.

Influence of Impact Velocity on the Residual Stress, Tensile Strength, and Structural Properties of an Explosively Welded Composite Plate

et al. 2020

This study aimed to analyze the effect of the impact velocity of a Zr 700 flyer plate explosively welded to a Ti Gr. 1/P265GH bimetallic composite on the residual stress formation, structural properties, and tensile strength. The residual stresses were determined by the orbital hole-drilling strain-gauge method in a surface layer of Zr 700 in as-received and as-welded conditions. The analysis of the tensile test results based on a force parallel to interfaces was used to propose a model for predicting the yield force of composite plates. Compressive residual stresses found in the initial state of the Zr 700 plate were transformed to tensile stresses on the surface layer of the welded Zr 700 plate. A higher impact velocity resulted in higher tensile stresses in the Zr 700 surface layer. To increase the resistance of the composite plate to stress-based corrosion cracking, a lower value of impact velocity is recommended in the welding process.

Zirconium (Zr) alloys have been widely applied in nuclear reactors due to their low probability of neutron capture, acceptable mechanical properties, and excellent corrosion resistance. [1-6] Zirconium alloys are commonly used as cladding tubes, fixed grids, or channel box in reactors. [2,3,6] The fabrication of Zr alloys components generally includes vacuum consumable melting, forging, extrusion, hot and cold rolling, recrystallization or stress relief annealing and so on. [7] Rolling and subsequent annealing are frequently used in the Zr alloy sheet and tube production, which actually determine the microstructure and texture, [7-10] thus playing a decisive role for the corrosion resistance, [11-14] creep resistance [15-17] and mechanical properties [18-20] of Zr alloys. Annealing can reduce the residual stress, recover the plastic deformation ability and tailor the grain size and texture, which plays a vital role in the Zr alloy fabrication. A special parameter was thus proposed to evaluate the effect of annealing. [21] The microstructure and the texture evolution during annealing are not only significantly affected by annealing condition, for example temperature [22,23] and holding time, [8,24] but also by the pre-annealing deformation. [6,25] Indeed, many research results on deformation and subsequent annealing in Zr alloys have been reported. Chen et al. [7] reported that the 30% rolling reduction combined with annealing at 580 C for 12 h imparted a superior plasticity to the Zr alloy. Kumara et al. [26] investigated the three stage of annealing in a moderately deformed Zr-4 alloy. They found that the changes in the misorientations, and corresponding rearrangements of dislocations, were the most efficient means of stress relief in Zr-4 alloy. Prakash et al. [27] investigated the microstructural and textural evolution of ZIRLO alloy during hot rolling at different temperatures. Their results show that the slip, twinning, and recrystallization played a role in the microstructure development during hot rolling. They also contributed to the texture development, lamellae break-up, and the formation of a bimodal microstructure. Jiang et al. [28] studied the effects of cold-rolling reduction, annealing temperature, and time on recrystallization behavior and kinetics of cold-rolled Zr-1Sn-0.3Nb-0.3Fe-0.1Cr alloy and found that the rate of the recrystallization increased with increasing annealing temperature and rolling reduction. Recrystallized grains nucleated preferentially at sites with high-density dislocation and deformation stored energy. Zhang et al. [29] studied the microstructure evolution and mechanical properties of Zr 98.2 Cr 1.8 during hot rolling, solution and aging treatment (STA). It was found the bimodal microstructure was the key factor to achieve high strength (ultimate tensile strength 818 MPa) and excellent ductility (18.4%) after STA at 750 C. Gerspach et al. [30] investigated the texture stability during primary recrystallization of cold-rolled Zr702 alloy and found that a small strain favored...
