1Influence of rare earth on the microstructure and age hardening response of indirect-extruded Mg-5Sn-4Zn alloy显示文摘The effects of Ce addition on the microstructure, age hardening response and mechanical properties of an indirect-extruded Mg-5wt.%Sn-4Zn (TZ54) alloy were investigated. Addition of Ce accelerated the aging response with the peak aging time moving from 300 h in TZ54 to 30 h in Mg-5wt.%Sn-4Zn-1Ce (TZE541), while the peak harness was similar to each other. The addition of Ce also caused an increase in the precipitation stability during overageing. Though the tensile strength of extruded TZ54 was improved by the addition of Ce, the tensile strength of the TZE541 was reduced after T6-treatment. The combined mechanical properties of the present as-extruded alloys by solution heat-treatment and artificial aging (T6) were comparable to commercial wrought magnesium alloys.程伟丽 PARK S S 唐伟能 KOO B H 2010Journal of Rare Earths2010,28,5:5
2Power management unit chip design for automobile active-matrix organic light-emitting diode display module显示文摘A power management unit (PMU) chip supplying dual panel supply voltage, which has a low electro-magnetic interference (EMI) characteristic and is favorable for miniaturization, is designed. A two-phase charge pump circuit using external pumping capacitor increases its pumping current and works out the charge-loss problem by using bulk-potential biasing circuit. A low-power start-up circuit is also proposed to reduce the power consumption of the band-gap reference voltage generator. And the ring oscillator used in the ELVSS power circuit is designed with logic devices by supplying the logic power supply to reduce the layout area. The PMU chip is designed with MagnaChip’s 0.25 μm high-voltage process. The driving currents of ELVDD and ELVSS are more than 50 mA when a SPICE simulation is done.KIM J H PARK J H KIM J H CAO T V LEE T Y BAN H J YANG K KIM H G HA P B KIM Y H 2009Journal of Central South University2009,16,4:4
