Abstract
The present invention is technological process of preparing lumpy amorphous alloy. During the sample is smelted fast in a high frequency furnace, are used a V-shaped induction heating and melt position controlling coil and a quartz funnel unit with V-shaped opening as sample holding container. When the smelted smaple is in suspension or semi-suspension state at some proper temperature, positive pressure air flow is led in to the melt so that the melt is sprayed into copper mold at high speed. One of the other important features is high speed rotated copper base as cooling base board while obtaining amorphous alloy sheet with some thickness.
Description
The present invention relates to the direct spray-casting process of preparing lumpy amorphous alloy processing method of a kind of suspended smelting melt.
Since the nineties, A.Inoue of northeastern Japan university and the W.L.Johnson of California Inst Tech USA almost prepare simultaneously Mg base and Zr base noncrystal alloy block materials in succession, so started the new focus of bulk amorphous alloy preparation at material science, developed at present and the bulk amorphous alloys system and the Zr base is arranged, Mg base, Fe base, the Cu base, the Nd base, Pd base etc., and develop amorphous alloy composite material.
The mechanical property of bulk amorphous alloys, physicals and chemical property etc. have some outstanding characteristics, show as the intensity height, corrosion resistance nature is strong, has new fatigue, fracture property or the like, these excellent performances all are with a wide range of applications bulk amorphous alloys on civil and military just.
At present, preparation method about bulk amorphous alloys has many kinds, for example: vacuum melting and suction casting water cooled copper mould method of cooling, after the sample fusing, quartz tube water quenching method, synthesis method under the high pressure, suspension high undercooling method, method or the like is coagulated in melt die casting soon, and every kind of preparation method has certain characteristics, and certain limitation and shortcoming are also arranged simultaneously.
The objective of the invention is to propose preparation bulk amorphous alloy processing method in the direct Spraying-casting copper mould of a kind of suspended smelting melt, rather than the free die body cooling technology of melt.
The technology of the present invention is utilized the high frequency furnace fusing sample that is rapidly heated, induction heating and control melt position coil are the special coiling of V-structure, the container of splendid attire sample is a V-type opening quartz funnel device, treat the suitable temp after sample melts, sample is in suspended state or half suspended state, align the melt position, moment feeds the malleation air-flow, melt is sprayed at a high speed in the copper mould of bottom, and copper mould can be made different shape, comprise the garden type, template, ring-like or the like, thereby the non-crystaline amorphous metal block materials of acquisition different shape, another important feature of the technology of the present invention be copper chassis with high speed rotating as cooling base, can obtain to have certain thickness sheet amorphous alloy material.
The present invention has the following advantages:
1. under the ratio-frequency heating condition, sample just can melt in tens seconds fast, reduced the contaminated time of melt, formed ability thereby increase substantially non-crystaline amorphous metal;
2. melt is in high frequency heating coil, and contactless with crucible or soft the contact is in suspension or half suspended state after the i.e. quick fusing of sample, reduces heterogeneous forming core chance, improved non-crystaline amorphous metal greatly and formed ability;
3. in shower furnace, with the process of high-purity Ar to the melt spray to cast, can improve the melt falling velocity, melt is contacted with mould as early as possible, not only improved the speed of cooling of melt, simultaneously can greatly improve the filling of melt, improve the density and the tolerance range of test specimen, be suitable for manufacturing comparatively complicated precision parts made of non-crystalline alloy mould.
Below by embodiment in detail the present invention is described in detail.
Embodiment 1
After weighing, Zr-Cu-Ni-Al alloy mother metal puts in the opening quartz funnel in the ruhmkorff coil, be in half suspended state by ratio-frequency heating fusing back molten drop, moment feeds high-purity argon gas winding-up molten drop and enters in the copper mould, sample solidifies after prove after the hot analyzing and testing of X-ray diffraction and DSC and formed non-crystaline amorphous metal, and sample size is φ 7 * 60 (mm) pole.
Embodiment 2
After Nd-Fe-Al-Y alloy mother metal is pressed the foregoing description 1 and handled, can form≤the circular coupon of φ 7 * 60 (mm).
Embodiment 3
After Zr-Al-Ni-Cu-Ti-Y alloy mother metal is pressed the foregoing description 1 and handled, can form≤the circular coupon of φ 7 * 60 (mm).
Claims (2)
1. suspended smelting and spray-casting process of preparing lumpy amorphous alloy, it is characterized in that: utilize the high frequency furnace fusing sample that is rapidly heated, induction heating and control melt position coil are the special coiling of V-structure, the container of splendid attire sample is a V-type opening quartz funnel device, treat the suitable temp after sample melts, sample is in suspended state or half suspended state, align the melt position, moment feeds the malleation air-flow, melt is sprayed at a high speed in the copper mould of bottom, and copper mould can be made different shape, comprise the garden type, template, ring-like or the like, thereby the non-crystaline amorphous metal block materials of acquisition different shape.
