Investigation of Pt-Mo Alloys

Optimizaton of Mo-Si-B Intermetallic Alloys

Mo-Si-B intermetallics consisting of the phases Mo3Si and Mo5SiB2, and a molybdenum solid solution (“ -Mo”), have melting points on the order of 2000 °C. These alloys have potential as oxidationresistant ultra-high-temperature structural materials. They can be designed with microstructures containing either individual -Mo particles or a continuous -Mo phase. A compilation of existing data shows...

Stress-induced Transformations in Ti-mo Alloys

MAGNETIC STATES INSTABILITY OF Pt-Fe ALLOYS

Neutron-diffraction measurements have been used to 'determine the temperature and composition dependences of the ordered single crystals of Pt-Fe alloys containing 32, 30.5 and 28 at% of iron. A qualitative model for the complex antiferromagnetic ordering in the system based on the experimental data and band structure calculations has been proposed. The ordered Pt-Fe alloys with more than 36 at...

High Temperature Erosion- Oxidation Behavior of Nickel- Based Alloys Containing Mo in Fluidized Bed Waste Incineration

High-temperature erosion-oxidation behavior of nickel-based alloys containing 0-7 wt.% Mo in fluidized bed waste incineration conditions was studied. A stream of hot condensed air with a flow rate of 25 L/min caused hot silica sand (700 °C) mixed with 0.5 wt.% of chloride salts to hit the specimens for 250 h. By removing the erosive factor, the high-temperature oxidation behavior of the alloys ...
