Poly (DL-lactide)/Poly (ethylene glycol) diblock copolymer is successfully synthesized with mPEG and DL-LA as main raw materials, the residual monomers of polymer were removed by recrystallization. FT-IR used to characterize structure polymer. Gas chromatography determine solvent The solubility in different solvents was determined, effect systems on removal discussed. results showed that Poly(D...

A secondary recrystallization Lab study focusing on the secondary recrystallization temperature and magnetic properties was carried out on cold rolling industrial samples of 3%Si grain-oriented electrical steel produced by low slab reheating temperature technology. The results showed a secondary recrystallization temperature, determined by the observed grain size change, of 1080 C with annealin...

In this paper, how structure-sensitive parameters derived from the hysteresis loop, like coercive field, remanent induction, and hysteresis losses, can be used to characterise recovery and recrystallization in cold rolled Ti-Nb stabilised interstitial free ultra low carbon steel is shown. The effect on hysteresis measurements of isothermal annealing treatments applied to industrially cold rolle...

We have used medium energy ion scattering, temperature programmed desorption, and atomic force microscopy to study the interface composition and thermal stability of epitaxial strontium titanate thin films grown by molecular-beam epitaxy on Si 001 . The composition of the interface between the film and the substrate was found to be very sensitive to the recrystallization temperature used during...

Secondary recrystallization id grain-oriented silicon steel is studied by the high-temperature background damping. Abnormal grain growth involves an abrupt drop of the background. The temperatures of initiation and completion of the secondary recrystallization are, thus, determined for the sane sample from the definite change in background with increasing temperature. The background measured on...

In this paper, the traceability of copper from the anode to the cathode and then the wire rod has been studied in terms of impurity content, microstructure, texture, recrystallization kinetics, and ductility. These characterizations were obtained based on secondary ion mass spectrometry, differential scanning calorimetry (DSC), X-ray diffraction, HV hardness, and electron backscattered diffract...
