Recovery of severely deformed ferrite was followed in situ by High Energy X Ray Diffraction during heating and isothermal holding experiments. Dislocation densities annealing were determined a modified Williamson Hall method. The deduced recovery kinetics compared to post-mortem hardness measurements. A temperature dependent saturation exhibited holding. density drop behavior cannot be reproduc...

Recent studies on Cu interconnects have shown that interface diffusion between Cu and the cap layer dominates mass transport for electromigration. The kinetics of mass transport by interface diffusion strongly depends on the material and processing of the cap layer. In this series of two papers, we report in Part I the interface and grain-boundary mass transport measured from isothermal stress ...

In this paper, application of ultrasonic techniques for defect detection in weldments of austenitic stainless steel and maraging steel is discussed. Applications of ultrasonic techniques for characterizing microstructural changes in AISI type 316 stainless steel and modified 9Cr-1Mo ferritic steel; thermomechanical processing of 15Cr-15Ni-2.3Mo-titanium modified austenitic stainless steel (allo...

Self-cleansing of transition metal nitrides is discovered to take place during ultrahigh vacuum annealing of TiN, NbN, and VN thin films. Native oxide layers from air exposure disappear after isothermal anneal at 1000 °C. Also, for TiN, the Ti 2p and N 1s X-ray photoelectron spectra (XPS) recorded after the anneal are identical to those obtained from insitu grown and analyzed epitaxial TiN(001)...

In the present research, the primary crystallization kinetics of the amorphous Fe85.3B11P3Cu0.7 alloy was analyzed using non-isothermal DSC measurements. The average and local activation energies, Ea, were determined by different isokinetic and isoconversional methods. The results obtained for activation energy in this research, show that due to the complexity of the primary crystallization pro...

Static recrystallization and grain growth behaviors were investigated in Mg-0.3Ce (wt%) alloy processed by equal-channel angular pressing (ECAP) for N = 1 (?eq 0.9), 2 1.9), 4 3.9) passes at 300 °C using route Bc annealed 450 5, 30, 60, 180 min. The results demonstrated that the microstructure texture are strongly related to strain level, second particles distribution, fraction of dynamic (DRX)...

A novel concept of varying the strain hardening rate a medium Mn steel with 8 wt.% by duration intercritical anneal after hot rolling was explored. It found that stability austenite phase showed an inverse square root relationship annealing and maximum linear stability. The change in attributed to continuous enrichment increasing duration. Twinned martensite also be most likely product martensi...

A differential detection method for three wheat viruses: Wheat yellow mosaic virus (WYMV), Japanese soil-borne mosaic virus (JSBWMV) and Chinese wheat mosaic virus (CWMV) using reverse transcription loop-mediated isothermal amplification (RT-LAMP) reaction was developed. All three primer sets, which were designed from the genome sequences of WYMV, JSBWMV and CWMV respectively, worked most effic...
