The use of severe plastic deformation for microstructural control (2002)
Furukawa, Minoru, Horita, Zenji, Nemoto, Minoru, Langdon, Terence G.
The microstructure of a metal may be very significantly changed by subjecting the material to severe plastic deformation (SPD) through procedures such as equal-channel angular pressing (ECAP) and...
Using severe plastic deformation for grain refinement and superplasticity (2001)
Langdon, Terence G, Furukawa, Minoru, Nemoto, Minoru, Horita, Zenji
The grain size of many metals may be reduced to the submicrometer or nanometer level using various procedures incorporating the application of severe plastic deformation. This paper examines the...
Using equal-channel angular pressing for refining grain size (2000)
Langdon, Terence G., Furukawa, Minoru, Nemoto, Minoru, Horita, Zenji
Equal-channel angular pressing is an effective tool for attaining ultrafine grain sizes in bulk materials. An important advantage of this technique over conventional metal-working processes, such as...
Advanced form of {xi}-factor method in analytical electron microscopy (1999)
Fujita, Takeshi, Watanabe, Masashi, Horita, Zenji, Nemoto, Minoru
This study describes development of the ξ-factor method proposed earlier. The development is attempted by incorporating the absorption correction term into the equation relating the mass thickness...
Wang, Jingtao, Furukawa, Minoru, Horita, Zenji, Nemoto, Minoru, Ma, Yan
The microstructure and mechanical properties of aluminum alloy 6061 have been evaluated at temperatures ranging from room temperature to about 725 K. The age hardening behavior, the temperature...
The Age-Hardening Characteristics of an Al-6061/Al2O3 Metal Matrix Composite. (1998)
Wang, Jingtao, Furukawa, Minoru, Horita, Zenji, Nemoto, Minoru, Ma, Yan
Experiments were conducted to determine the age hardening behavior of an al-6061 metal matrix composite reinforced with 20 vol pct of al2o3 microspheres and prepared using liquid metallurgy...
An Investigation of Strain Hardening and Creep in an Al-6061/Al2O3 Metal Matrix Composite. (1998)
Furukawa, Minoru, Wang, Jingtao, Horita, Zenji, Nemoto, Minoru, Ma, Yan
Experiments were conducted to compare the influence of temperature on the flow and strain-hardening characteristics of an al-6061 metal matrix composite, reinforced with 20 vol pct of al2o3-based...
Application of {xi}-factor method to Ti-Al-Cr system in analytical electron microscopy (1998)
Tanaka, Satoru, Watanabe, Masashi, Horita, Zenji, Nemoto, Minoru
This study presents quantitative microanalysis of the Ti-Al-Cr system using analytical electron microscopy. The absorption correction is made using the ξ-factor method developed recently, which does...
HORITA, Zenji, SANO, Takeshi, NEMOTO, Minoru
The extrapolation method is applied to the determination of the absorption-free kANI factors, (kANI)0, in thin-film X-ray microanalysis where A=Al(Kα), Ti(Kα), Mo(Kα, Lα), Ta(Lα, Mα) and...
