摘要： PROBLEM TO BE SOLVED: To solve problems that it takes time in measuring a shape memory function of a shape memory alloy, and a load on the quality control for individual products is heavy.
SOLUTION: When a ferrous shape memory alloy is manufactured by a centrifugal casting method, the quality control of individual products is important. A plurality of test pieces are sampled from one or a plurality of samples belonging to the same composition range and manufactured under the same condition, the tensile strength or proof stress is detected for each test piece, a predetermined stress is exerted in each test piece to give a strain, and the test piece is heated to a predetermined temperature to measure the shape recovery ratio. A primary function to correlate individual results of the tensile strength or proof stress and each shape recovery ratio is specified, and the shape memory function of every pipe joint to be manufactured with the same composition and under the same manufacturing condition is individually estimated from the primary function to considerably save the load.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing pipe joints of an iron based shape- memory alloy having substantially uniform columnar crystal rate i.e., shape- memory function over the whole length by a centrifugal casting method.
SOLUTION: The columnar crystal rate exceeds at least 70% of the wall thickness over the whole length of a pipe in any transverse cross section, by beginning casting of molten steel with predetermined composition from the casting point arranged at the one end of the mold rotating at high speed, continuing the casting while moving the casting point to the other end at constant speed in a direction of rotating axis of the mold, and spraying exothermic- insulating flux on the surface of the cast molten steel and moving it to the other end of the mold. Further, it is most desirable to use Ca-Si based flux as the exothermic-insulating flux.

SOLUTION: The molten metal outlet 2, i.e., a head of a tilting base 1 of the conical type ladle, is formed by a compound refractory layer together with an inner iron plate 21 installed vertically on an enclosed iron plate 11 up to the top surface of a refractory mortar 13, a porous iron plate 22 fastened perpendicular to the enclosed iron plate 11 in parallel with the inner iron plate 21 at intervals, which is integrally bonded to the inner iron plate 21 by using both a front refractory mortar 25 covering both sides of the iron plate while filling and communicating numerous porosity 23 of the iron plate and a rear refractory mortar 24. As the integrally bonded compound refractory layer will not be fallen off even if a gap or a crack is generated when used, it may bring a marked improvement in durability than ever before. In practice, an open area ratio of the porous iron plate is 5-35%, most desirably 20%. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To form a reforming layer to a desired depth from the surface of a steel material and to simply perform this formation at a low cost.
SOLUTION: A rotating tool T rotating at high speed is brought into contact with the surface of the steel material W and then, the contact part of the steel material W with the rotating tool T is softened with frictional heat and this softened part is stirred with a probe 2 to reform the steel material W. Since this rotating tool T is composed of a heat-resistant cemented carbide mainly composed of a tungsten carbide, wear hardly occurs, even in the temperature zone of ≥1,000°C where the steel material W is softened. The depth of the reforming layer 3 can be made a desired depth by changing the length of the probe 2 projectingly arranged on the rotating tool T. Further, when performing this treatment in a state the rotating tool T is inclined to the back part in the advancing direction, since a fluid f2 vertically stirring the softened steel material, is generated with the inclined probe 2, stirring with the fluid is more effectively performed.

摘要翻译：要解决的问题：从钢材的表面形成到所需深度的重整层，并且以低成本简单地进行这种形成。解决方案：高速旋转的旋转工具T与钢材W的表面接触，然后钢材W与旋转工具T的接触部分用摩擦热软化，该软化部分与探针2一起搅拌以使钢材W重整。由于该旋转工具T由主要由碳化钨构成的耐热硬质合金组成，所以即使在≥1000℃的温度区域也难以发生磨损，钢材W软化。通过改变突出设置在旋转工具T上的探针2的长度，能够将重整层3的深度设为期望的深度。此外，当在旋转工具T中的后部倾斜的状态下进行该处理时由于倾斜探针2产生垂直搅拌软化钢材料的液体f2，因此与流体的搅拌更有效地进行。版权所有（C）2008，JPO＆INPIT
