Dynamic recrystallization and grain size effects in shock hardened copper

Steady-State Grain Size in Dynamic Recrystallization of Minerals

Primary Recrystallization and Grain Growth of Tough Pitch Copper Wire

Tough pitch copper wire (99.97% Cu) is generally characterized by the spiral elongation number. The principle of the test is based on the influence of impurities on the recrystallization kinetics. Alternative non-metallographic techniques to characterize the recrystallization kinetics have been investigated in this study, such as differential scanning calorimetry (D.S.C.) and residual electrica...

A mean field model of dynamic and post-dynamic recrystallization predicting kinetics, grain size and flow stress

A physically-based two-site mean field model has been developed to describe the microstructural evolution due to recrystallization during and after deformation. The model has been applied to predict the recrystallized fraction, recrystallized grain size, and flow stress of 304L austenitic stainless steel during discontinuous dynamic recrystallization (DDRX), post-dynamic recrystallization (PDRX...

Investigation of Recrystallization and Grain Growth of Copper and Gold Bonding Wires

Copper bonding wires were characterized using electron backscatter diffraction (EBSD). During drawing, shear components are mainly located under the surface and ,111. and ,100. fiber texture components develop with similar volume fractions. Grain average misorientation (GAM) and scalar orientation spread (SOS) of the ,100. component are lower than those of the ,111. or other orientations. Also,...

Copper Precipitation Hardened, High Strength, Weldable Steel

Steel containing 0.03% carbon, 1.35% copper and 0.84% nickel had yield strength in the 540-625 MPa (78-90 Ksi) range depending on thickness, ultimate tensile strength in the 625-690 MPa (90100 Ksi) range, and 25-30% elongation when air cooled after hot rolling. No brittle heat-affected zone was formed during manual or automatic submerged arc welding without pre-heating or postheating. The fract...
