The deformation properties of a TiC-Mo eutectic composite were investigated in a compression test at ... suggests that the excellent high-temperature strength is due to the constraining of thedeformation in the Mo ... toughness is ascribed to the frequent branching of crack paths as well as to the plasticdeformation of the Mo
Freeze drying for porous Mo was accomplished by using MoO3 powder as the source and camphor-naph- thalene ... To convert the MoO3 to metallic Mo, the green body was hydrogen-reduced at 750o C, and sintered at 1100o
To investigate the deformation properties of TiC-(5-20)mol% Mo solid solution single crystals at high ... In the higher temperature range, τ0.2 increases monotonously with an increasing Mo content. ... The critical resolved shear stress (τ0.2)at the high temperature range showed that Mo content dependence
The materials for this study are 1.25Cr-0.5Mo and 2.25Cr-1Mo steels used at high temperature and pressure ... Hydrogen appeared to have many effects on the mechanical properties of the Cr-Mo steel alloys.
by the ball-milling for a 3:7 mixture of pure Cu and Mo, the evidence for which has been deduced from ... We conclude that two phase mixture of nanocrystalline fcc-Cu and bcc-Mo with grain size of 10 nm is formed
Mo thin films were used for the back electrode because of the low resistivity in the Mo/CuInGaSe2 contact ... inchalcopyrite solar cells. 1µm thick Mo thin films were deposited on soda lime glass by varying the ... The effects of the Ar pressure on the morphology of the Mo back electrode were studied andthe relationships

The hardenability of low-carbon boron steels with different molybdenum and chromium contents was investigated using dilatometry, microstructural obse..
TiC-21mol% Mo solid solution (δ-phase) and TiC-99 mol% Mo solid solution (β-phase), and TiC-(80~90)mol ... %Mo hypo-eutectic composite were deformed by compression in a temperature range from room to 2300 K and ... found that the high strength of the eutectic composite is due primarily to solution hardening of TiCby Mo
The structural and efficient properties were investigated by varying the thickness of the Mo:Na layer ... As a result, when the Mo:Na thickness was 300 nm on soda-lime glass, the measured Na content was 0.28 ... Through the optimization of the Mo:Na layer, a solar conversion efficiency of 11.34% was achieved.
