For the purpose of precise microstructure replication and complete filling  effects of various imprint parameters  including imprint temperature  imprint time and compression load  on formability of La 62Al14Cu12Ni12BMG are studied and discussed. Scanning electron microscope images and results of thermal analysis are used to characterize the filling effect of La62Al 14Cu12Ni12BMG. In particular  correlations between time and thermodynamic properties are presented. Despite of its high viscosity at crystallization temperature and its narrow supercooled liquid region  La62Al14Cu12Ni12BMG is proved to be a durable and promising material which can precisely replicate the patterns of silicon mold and then transfer its own patterns on Ce 69Al10Cu20Co1BMG and PMMA. 2012 Elsevier B.V.

Although many theories on image motion are proposed to cope with this problem  few simulations are done to justify the proposed theories on ground. And thus  in this paper  a ground-based physical simulation system for TDI CCD imaging is developed and specified  which consists of a physical simulation subsystem for precise satellite attitude control based on a 3-axis air bearing table  and an imaging and simulation subsystem utilizing area-array CCD to simulate TDI CCD. The designed system could realize not only a precise simulation of satellite attitude control  whose point accuracy is above 0.1 and steady accuracy above 0.01/s  but also an imaging simulation of 16-stage TDI CCD with 0.1s its integration time. This paper also gives a mathematical model of image motion of this system analogous with satellite-borne TDI CCD  and detailed descriptions on the principle utilizing area-array CCD to simulate TDI CCD. It is shown that experiment results are in accordance with mathematical simulation  and that the image quality deteriorate seriously when the correspondence between the image velocity and signal charges transfer velocity is broken out  which suggest not only the validity of the system design but also the validity of the proposed image motion theory of TDI CCD. 2010 SPIE.
