Homogenizing Analysis for Sintering of Bio-Titanium Alloy (Ti-5Al-2.5Fe) in MIM Process.

Abstract

The model suggested by Ashby and Coble was used to analyze the sintering process of pure titanium in this paper. Then based upon this result, homogenizing behavior of alloying elements of aluminum and iron during sintering was further discussed for bio-titanium alloy Ti-5A1-2.5Fe. Using this method, the concentration variation of alloying elements was calculated to indicate the effect of element diffusion on the structure transformation. It was shown that the calculated results were in agreement with the results obtained in the previous experiments.

Influence of TiC, TiN and TiC(N) additions on sintering and mechanical properties of injection moulded titanium based metal matrix composites

“…At the same time, the high strength to weight ratio and high resistance to corrosion make titanium and its alloys ideal materials for many applications. [3][4][5] One major barrier to a wide spread use of titanium and titanium alloys, especially for the cost conscious industries, is the inherent high cost of materials and component fabrication. Especially, very limited consideration of Ti application in automotive industries should be noted and high cost of processing is still the major problem in this sector.…”

Effect of additives on sintering response of titanium by powder injection moulding

“…At the same time, the high strength to weight ratio and high resistance to corrosion make Ti and its alloys ideal materials for many of these same applications. [1][2][3] However, a difficulty occurs in fabricating components at a low cost from an expensive material. Considering powder metallurgical production routes, simple die compaction offers limited shape complexity, therefore compaction is not useful in many small component designs.…”
