Obtaining high strength without sacrificing ductility in Mg alloys is of great importance. However, the hexagonal close-packed crystal structure critically limits deformation alloys. In this work, novel Mg-1.5Zn-0.5Zr-0.5Sr (wt.%) were fabricated through homogenization, direct extrusion (DE), and extrusion-shearing (ES) processes. The effects three different processes on microstructures, texture, mechanical properties thoroughly investigated. results show that average grain size alloy was...
The effect of grain boundaries on the strength and electrical conductivity annealed copper wires was studied. After annealing at 100°C for 30 min, retained a fiber-like structure. increase in is believed to stem from decrease crystallographic defects introduced by drawing. Recrystallization occurred when temperature reached 150°C. formation small recrystallized grains led introduction additional perpendicular drawing direction, resulting slight conductivity. When rose up 200°C, complete...
Abstract Copper and Cu-Fe alloy wires were cold drawn at room temperature, the microstructure properties characterized analyzed. The results show that, same drawing strain, strength ductility of are higher than those copper wires. At a strain 4, tensile elongation is about 5%, much 2% for pure For wires, with increasing Fe phase elongated along direction forms fiber structure <110> texture. In addition to <111> <100> textures in wire, high-intensity texture <112>...
Heavy-cold-drawn Cu-20wt%Fe wires were annealed at temperatures ranging from 150-600°C. The microstructure and properties studied using scanning electron microscope, high-resolution transmission microscope accompanied with tensile conductivity testing. results show that, as the annealing temperature increases, strength of decreases monotonically, but electrical first increases then decreases, reaching its peak value after 500°C. decrease in is related to dislocation recovery static...
