Generally a MPF (Magnetic pulse forming) process refers to the high velocity and high strain rate deformation of a low-ductility materials driven by electromagnetic forces that are generated by the rapid discharge current through the forming coil. The goal of this study was to investigate the ...

the field-shaper or the tube generate heat losses and the temperature might increase during the process. Therefore, couplings between the magnetics and the mechanics on one side and between the magnetics and the thermal effects on the other side are required. The complete electromagnetic and...
Experimental and numerical research on magnetic pulse forming of DP600 high-strength steel with driver sheetMagnetic pulse forming is high velocity forming technology, which requires the workpiece with better conductivity. However, high-strength steel with lower conductivity is difficult to deform by......
Magnetic pulse compression(MPC)system has been widely-used for over a few decades as a technique for producing short-duration,high-peak-power pulses reliably.A novel MPC system which does not contain external demagnetization circuits,has broadened the application of MPC systems.Improvements for novel...

At the beginning of the process, all heaters were set and stabilized at 250 °C for 1200 s. TDMAT and oxygen were introduced through ALD valves with a flow rate of 30 sccm and a pulse duration of 0.1 s, respectively. Pulse and purge times were kept constant for 600 cycles at...
A method for forming a disk of a disk drive having a magnetic head for reading data from or writing data to the disk is introduced. The disk is formed of a disk substrate. Additionally, a laser process using a pulse laser with a pulse width of 2090 ns and an energy of 0.56.0 μj...
Since, in the 3D racetrack devices the DW velocity may vary along the racetrack due to the presence of protrusions, we define the DW velocity in this case by dividing the total length of the channel with the total current pulse time used to drive the DW from one end of the channel ...
The MRAM read process consists of applying a bipolar current pulse to the word line. This pulse produces a field sufficient to switch the soft layer but not the hard layer: Hc1 < Hword < Hc2. Thus, depending upon the state of the element, “0” or “1,” the resistance in the sense...
