Definitions
- the invention relates to alloys based on AI which are essentially amorphous or microcrystalline.
- alloys in the amorphous state obtained by rapid cooling at a speed generally greater than 10 3 ° C / sec. from a disordered state (liquid or vapor).
- Particularly known are alloys of type T i X j , in which T represents one or more transition metals (in particular iron) and X one or more metalloids (or not) such as B, P, Si, C , AI with i> 50 at.%.
- the AI intervenes as a minor element whose content in general of the order of 10 at.%, Does not exceed 35 at.%.
- amorphous alloys have been developed by A. INOUE et al (Journal of Mat. Science, 16, 1981, p. 1895) but relate to the systems (Fe, Co, Ni) -Al-B which may contain up to 60 at.% AI and in general from 15 to 45-50 at.% B.
- Fr-A-1 599990 describes alloys based on AI which, although obtained with a high cooling rate ( ⁇ 10 5 to 10 7 ° C / sec) are crystallized. Indeed, we meet there “a finer and harder grain structure (page 2, line 15) or even“ columns of grains having a diameter of the order of a micron (page 5, lines 31-32) or even that "the desired structure A is characterized by a very fine dentritic structure. “This document therefore reveals the existence of binary alloys AI-Fe (Co, Ni, Zr, Mo, W) microcrystallized and not amorphous.
- the invention therefore relates to alloys based on AI at least ternary and free of boron, which can be obtained in an essentially amorphous state by cooling at speeds of the order of 10 5 to 10 S K / sec , which it is possible to obtain industrially, from a liquid or gaseous state and a process for obtaining microcrystalline alloys from the crystallization of said alloys in the amorphous state.
- essentially amorphous alloy is meant a state in which the atoms have no order at long distance, characterized by broad and diffuse X-ray diffraction spectra, in the absence of lines characteristic of the crystallized state; the corresponding electron microscopy examinations show that more than 80% by volume of the alloy is amorphous.
- microcrystalline state means an alloy in which 20% of the volume or more is in the crystallized state and the average size of the crystallites of which is less than 1000 nm, preferably less than 100 nm (1000 ⁇ ). This average dimension is evaluated from the width at mid-height of the line of the dense planes of the alloy, or by electron microscopy (in black field). In this state, the diffraction lines at small angles ( ⁇ ⁇ '22 °) have disappeared.
- the invention also relates to a process for obtaining microcrystalline alloys by thermal treatment of crystallization as indicated in claim 7.
- the content of additives is limited above due to metallurgical considerations (melting temperature, viscosity, surface tension, oxidability, etc.), but also economic (price, availability). Mo and W are limited to 15% because they significantly increase the density and the melting point of the alloy.
- Essentially amorphous or microcrystalline alloys have been obtained with alloys containing between 6 and 25% at. Cu with a value of 15 ⁇ b ⁇ 40 at.%, the impurities being kept below 1 at.%.
- the alloy Al 80 Cu 10 Ni 8 Mo 2 obtained above and which has a crystallization temperature Tc 156 ° C and a density of 3.7 g / cm 3 , a ratio of the electrical resistance to the state amorphous with respect to the resistance in the crystallized state at 300 ° K of 7, was subjected to maintenance at 150 ° C;
- FIG. 2 gives the evolution of the Vickers micro-hardness under 10 g, during this test: it reaches 500 HV approx. after 10 h.
- the Al 72 Cu 15 V 10 Mo 1 Si 2 alloy prepared as in Example 1 has a crystallization temperature of 360 ° C. and a density of 3.6 g / cm 3 . Its micro-hardness reaches 750 HV after 1/2 hour at 400 ° C and 840 HV after 1/2 hour at 450 ° C.
- the very high hardnesses are favorable for obtaining powders of very high chemical homogeneity, by grinding.
- the alloys according to the invention can be obtained according to known techniques in the form of wires, strips, ribbons, sheets or powders in the amorphous state and / or in the microcrystallized state. They can be used either directly or as reinforcing elements of other materials or they can also be used for obtaining surface coatings improving for example the resistance to corrosion or wear.
