Mars Atmosphere Argon Density Measurement on Mer Mission

Introduction Using the Alpha Particle X-ray Spectrometer (APXS) (see Fig.1) on board Spirit and Opportunity rovers on MER mission, we were able to measure the argon density variation in the martian atmosphere as a function of seasonal changes. Due mainly to the variation of the temperature as a function of season on martian poles, the air mass on Mars is constantly moving from North pole to Sou...

In situ Investigation of Titanium Powder Microwave Sintering by Synchrotron Radiation Computed Tomography

In this study, synchrotron radiation computed tomography was applied to investigate the mechanisms of titanium powder microwave sintering in situ. On the basis of reconstructed images, we observed that the sintering described in this study differs from conventional sintering in terms of particle smoothing, rounding, and short-term growth. Contacted particles were also isolated. The kinetic curv...

Titanium Powder Sintering in a Graphite Furnace and Mechanical Properties of Sintered Parts

Recent accreditation of titanium powder products for commercial aircraft applications marks a milestone in titanium powder metallurgy. Currently, powder metallurgical titanium production primarily relies on vacuum sintering. This work reported on the feasibility of powder sintering in a non-vacuum furnace and the tensile properties of the as-sintered Ti. Specifically, we investigated atmospheri...

Fabrication of porous titanium implants by three-dimensional printing and sintering at different temperatures.

This study evaluated the feasibility of using three-dimensional printing (3DP) to fabricate porous titanium implants. Titanium powder was blended with a water-soluble binder material. Green, porous, titanium implants fabricated by 3DP were sintered under protective argon atmosphere at 1,200, 1,300, or 1,400°C. Sintered implant prototypes had uniform shrinkage and no obvious shape distortion aft...
