単ロール液体急冷法に用いる母合金はアーク溶解法を利用して作製した。
アーク溶解法はタングステン電極を用いてアーク放電を起こし、その際に発生する多量の熱を用いて高い融点を持つ金属試料を溶解させる方法であり、元素が均一に混ざった状態の合金を調製することができる[61]。減圧高純度アルゴン雰囲気中で非消耗タングステン電極型アーク溶解炉を用いてCuTi 母合金、NiZr母合金を溶製した．以下にNiZr母合金作製方法を示す。
本研究では均一なNi40Zr60母合金を15 g作製するためにNi板4.5 g, Zr板10.5 gを準備し、それぞれ短冊状（1 cm×4 cm）に切り、その短冊状板をNi・Zrと交互になるように並べ、余った細長い板でまとめた(Fig. 2-1)。アーク溶解炉装置図はFig. 2-2に示したように真空容器、銅製水冷ハースおよびアーク用電極からなる。アーク炉による試料作製手順について述べる。銅製水冷ハースにある溝に作製する試料の原料とTiの酸素ゲッターを置き、容器を真空にする。酸素などが試料に混入するのを防ぐために1×10-3以下になるまで真空引きを行い、その後真空引きを止め、ガスクリーナーを通して1気圧弱のArを導入した。電極を酸素ゲッター金属用のチタンに近づけてアーク放電を始める。Tiを赤熱し、完全に溶解するまで温めて容器中の残留酸素をチタンに吸着させる。その後安定して放電が続く状態で電極を固定し、試料にアークを集中照射する。そのときのアーク電流は百アンペア前後である。溶解した試料はボタン状であり金属光沢を持つ。試料の各部分を均一に溶解させ不純物相のない良質の試料を作製するために、試料を反転棒で操作し裏返し、溶解作業を6回繰り返した。CuTiの母合金も同様の方法を用いて作製した。
作製した母合金は単ロール法で用いる石英管ノズルに入るサイズにマイクロカッターを用い切断し、単ロールの際に膨張し石英管を割ることがないように角はエメリー紙で削った。試料は水、アセトンで洗浄し保管した。

Alloys used in the single role liquid rapid method using ARC melting technique and prepared.ARC-melting method can be prepared how prone arc discharge using a tungsten electrode, occur when large amounts of heat with high melting point metal materials to dissolve elemental mixture evenly State alloy [61]; In low pressure high purity argon atmosphere using a non-consumable tungsten electrode type arc furnace cuti mother, NiZr alloys made from. NiZr mother alloy preparation method shown below.Outlines the 4.5 g Ni, Zr plate 10.5 g prepare uniform Ni40Zr60 alloys 15 g prepared this paper, each cut into strips 1 cm x 4 cm, strips Board and Ni-Zr would alternately arranged extra long Board (Fig. 2-1). ARC melting furnace system diagram fig. 7. A vacuum chamber, water-cooled copper hearth and electrodes for arc as shown in 2-2. Describes a sample preparation step by arc furnaces. Place the oxygen getter material samples prepared in the Groove on the water cooled copper hearth and Ti, to evacuate the vessel. Perform vacuum up below 1 x 10-3 to avoid contamination oxygen, such as, stop vacuuming then introduced the Ar slightly less than 1 ATM through gas purifiers. Move closer to the oxygen getter for metallic titanium electrodes, arc discharge begins. Red-hot and Ti, until completely dissolved and snap to titanium residual oxygen in the vessel. Fixed electrode with stable thereafter, followed by a discharge, irradiation arc concentration in samples. The arc current is in hundred amps before and after. Dissolved samples, button-shaped with a metallic sheen. And manipulate the samples with a reverse stick to fabricate high-quality samples of impurities not dissolve uniformly in each part of the sample to turn over the work by dissolving 6 times repeated. Prepared by same way CuTi alloys. So can crack the quartz tube mother alloy used micro cutter on size enters the quartz tube nozzle uses a single roll cutting and swell, just roll when not horns sharpened with Emery paper. Samples were washed with water, acetone, was kept.

Master alloy for use in the single-roll liquid quenching method was prepared using an arc melting method.
Arc melting method to cause an arc discharge using a tungsten electrode, and a method of dissolving the metal samples with a higher melting point by using a large amount of heat generated at that time, to prepare the alloy state elements mixed uniformly It can [61]. CuTi mother alloy using a non-consumable tungsten electrode arc melting furnace under reduced pressure and high purity argon atmosphere, I was melting the NiZr mother alloy. I show the NiZr mother alloy manufacturing method below.
Ni plate 4.5 g to 15 g produce a uniform Ni40Zr60 mother alloy in this study, and to prepare the Zr plate 10.5 g, cut into strips (1 cm × 4 cm), respectively, the rectangular plate and Ni · Zr side by side so as to alternately, are summarized in the elongated plate surplus (Fig. 2-1). Arc melting furnace equipment diagram Fig. Vacuum vessel, as shown in 2-2, consisting of copper water-cooled hearth and arc electrode. I describe the sample preparation procedure by the arc furnace. Place the oxygen getter material and Ti of samples making the groove in the copper water-cooled hearth, and the container evacuated. Is performed evacuated to oxygen etc. is 1 × 10-3 or less in order to prevent the contamination in the sample, then stopped vacuum and introducing Ar at 1 atm weak through the gas cleaners. To start the arc discharge as close an electrode on titanium for oxygen getter metal. Is red hot the Ti, warmed until complete dissolution and adsorption of residual oxygen in the container titanium. Then the discharge electrodes are fixed in a subsequent state stable, concentrate irradiating the arc sample. Arc current at that time is one hundred amps and forth. The dissolved sample is a button-like with a metallic luster. To make the quality of the sample without homogeneously dissolved cause impurity phase of each portion of the sample, the sample is operated by an inverted bar inside out, was repeated dissolving work six times. CuTi mother alloys I was prepared using a similar method.
The prepared master alloy was cut using a micro cutter in size entering the quartz tube nozzle used in a single roll method, corners so as not to divide the inflated quartz tube during the single roll was cut by emery paper. The samples were stored was washed with water, with acetone.

Arc discharge is caused by using a tungsten electrode arc melting method, the method has high metal samples using a large amount of heat is generated in the melting point at the time of the preparation of mixed uniform alloy elements 61 may be CuTi alloys by non-consumable tungsten electrode arc melting furnace in low pressure high purity argon atmosphereMother prepared NiZr alloy preparation method NiZr alloys are shown below. Ni plate 4.5 g, for uniform Ni 40 to 60 g mother alloy Zr 15 in this study to prepare Zr rectangular plate 10.5 g, respectively (1 cm), so that the rectangular plates are alternately Ni and summarized in the Zr and the rest of the elongated plate Fig 2 1 Fig. Fig arc melting furnace apparatus as shown in the second vacuum container 2, and water cooling copper hearth for arc electrode. By arc furnace in the sample preparation procedure is described.Put Ti oxygen getter material and sample preparation in the groove in the water cooling copper hearth, a vacuum container. Vacuum to be less than 1 × 10 - 3 in order to prevent mixing of oxygen in the sample, and then through the vacuum cleaner, gas pressure Ar weakness. Starting arc discharge in oxygen getter metal titanium closer to the electrode. To Ti red hot, heated until completely dissolved in the container to adsorb residual oxygen titanium.After the electrode is stably fixed on the sample, followed by the discharge concentration is applied to the arc. When the arc current is about hundreds of amperes. The sample was dissolved with metallic luster and button. For each part of the sample uniformly dissolved to produce good quality without impurity phase sample, the inside out by operating the reversing bar sample dissolution, repeated six times. The CuTi master alloy prepared by using the same method. AtBy using micro cutting cutter size prepared by the mother alloy into the quartz tube nozzle used in the single roll method, emery paper angle of single roll so that it does not break when the quartz tube is expanded. The water sample, washing with acetone. At
