Introduction

The formability of the extruded alloy was also examined by compression test at a strain rate of 0. The nano-Q alloy exhibits higher tensile strength values at room temperature and elevated temperatures of to K, higher wear resistance, higher Young's modulus and lower coefficient of thermal expansion in comparison with AT6 alloy, though the elongation is lower and the density is higher. The newly developed nano-Q Al-Fe-Cr-Ti-Co-Mo alloy has been tested for applications to some heat-resistance parts in automobiles at present. Here it is important to describe that the development of new Al-based alloys by use of the homogeneous dispersion of nanoscale quasicrystalline phase surrounded by the fcc-Al phase has been carried out at present in many countries 45 - 48 by the trigger effect of our data 34 , 37 - The reinforcement of Al crystalline alloys with bulk glassy alloys is expected to enable the production of novel Al-based alloys with features of inexpensive PM metallurgy process, high specific strength, good ductility and material weight reduction.

We chose three kinds of bulk glassy alloys, i. The simple production method to produce the Al-based bulk alloy with high strength and high ductility is attractive for future development of new PM Al-based composite alloys. Thus, the grain size decreases drastically in the vicinity of 1. The 0. The highest tensile strength attained was about MPa at 2. In addition to the high tensile strength, the Al-Fe alloy sheets with 0.

Both hardness and tensile strength are proportional to the reciprocal square root of the grain size, as shown in Figure The Al-Fe alloy sheets also show a good Hall-Petch relation even in the high tensile fracture strength level of to MPa. Similar high strength nanocrystalline alloy sheets were also produced for Al-Zr and Al-Fe-Zr sheets For instance, the Al It is thus concluded that the Al-Fe sheet is a high strength and high fracture toughness type, while the Al-Fe-Zr sheet is a high elevated temperature strength type material.

The structural change caused a significant change of Knoop hardness from for Al-phase to for AlN through to for the amorphous phase, as shown in Figure The amorphous phase had a wide range of Knoop hardness values ranging from to with increasing partial nitrogen pressure from 0. Similar changes in the structure and Knoop hardness have also been obtained for Al 0. The real application fields were robot parts such as arm, finger and foot, machinery parts, die cast molds, sporting goods such as soft baseball bat, tennis racket and golf club etc. The achievement of application is due to the simultaneous satisfaction of the high specific strength, high specific modulus, high fatigue limit, low coefficient of thermal expansion, low wear resistance and high corrosion resistance.

We have developed metastable Al-based alloys consisting of amorphous, nanocrystalline and nanoquasicrystalline phases. These new metastable Al-based alloys exhibit high static and dynamic mechanical properties, high elevated temperature strength and good workability which have not been obtained for conventional Al-based crystalline alloys. It is expected that bulk metastable alloys with more functional characteristics and larger material dimensions will be obtained through the fabrication of new structures via novel alloy compositions and production processes.

It is believed that the further developments of these novel Al-based metastable alloys will contribute greatly to the future sustainable society.
