چکیده
Abstract We present a fundamentally different approach to process the bimodal Ti-based alloy (Ti-Nb-Fe-Co-Al) by semi-solid sintering stemmed from hypoeutectic reaction, aiming at achieving ultrafine eutectic structure, β-Ti and micron-sized dispersed phase with strengthening effect. As expected, microstructure of processed Ti-Nb-Fe-Co-Al contains local structure (β-Ti TiFe), residual equiaxed Ti 2 Co. This possesses excellent properties, yield strength is 1620MPa large plastic strain 20%, superior those previous fully casting. The novel idea helpful fabricate high-performance alloys metals, which belonging high temperature systems.

It is well known that semi-solid forming could only obtain coarse-grained microstructure in a few alloy systems with a low melting point, such as aluminum and magnesium alloys. This work presents that semi-solid forming could also produce novel bimodal microstructure composed of nanostructured matrix and micro-sized (CoFe)Ti2 twins in a titanium alloy, Ti62Nb12.2Fe13.6Co6.4Al5.8. The semi-solid...

Supersaturated Al-Ti-Cr alloys were produced by a continuous electron beam evaporation technique. The as-deposited alloy sheets were fcc supersaturated solid solution with an average grain size of about 400 nm. Due to the fine grain size, the hardness of the alloy was as high as 270Hv. The sheet showed age hardening, and the peak hardness of 340Hv was obtained after aging at 623K for 900 s, in ...

Controlling crystal nucleation and growth leading to formation of nano structures by an original flux treatment method mainly in calcia and magnesia crucibles followed by water-cooling allowed production of Ti45Cu45Fe10 bulky nanostructured alloy of 16mm in diameter. Since a glass forming ability (GFA) of the alloy composition is low, the alloy could not form an amorphous structure even by a co...
