Preparation of elemental powder mixture of Ti-6Al-4V alloy sintering and forging characteristics
Be strong in the ingot. But the hydrogen pressure is too high will cause increased losses of aluminum smelting process led to changes in composition, in order to obtain an average particle size smaller and larger proportion of Al5 phase of Al powder. Hydrogen partial voltage-controlled Si-5% ~ 20% of the question, the best. Nb-Al fragmentation of the components of homes Jin Fasheng 62at% ~ 75at%, but the resulting powder composition is 66at% ~ 75at% Nb, In addition, the formation of thin single-phase Nb 72at% weed is a composition of 75at% Nb. Chou indigo in touch application content to play things more weed made this pupil, a,,: Wang Xuan-ling open to, 'f. . Preparation of elemental powder mixture of _ri a 6AI a 4V alloy; Lei, sintering and forging characteristics of the small blocks F 'Susan Chan z + (a 2.36 × 10 a) a +2.08 x10 one, · l0 · a shape of the sintered forging speed small, the internal void volume decreased. At the same speed forging, metal flow favorable for the shape, void volume can be reduced. Forged after the hammering in the vicinity of the specimen and at the bottom of the metal mold. Residual sintering organizations and gaps, this is due to sintering furnace removed from the beginning to forge some 10s interval,[link widoczny dla zalogowanych], due to the temperature dropped to l273K. Thus, to eliminate the gap in the sintered bodies to improve the forging load, speed and a lower forged metal flow in forging shaved wood in the shape to be effective. (Hao Lei Xing) Combustion synthesis of metal compounds and Prospect between the assimilation of metal objects by people looking forward to Taiwan for a variety of areas, but in fact one of the reasons is extremely slow spread is difficult using traditional casting methods Preparation of the kinds of materials. Down, such as, T thorium metal and nickel compounds asked the proportion of poor doubled. T / AI in the difference between the melting point of titanium and aluminum l000K; and metal objects to ask the elements of Taiwan, there are many in the molten state, reacted strongly with the crucible. In addition, Ling thermoplastic processing most difficult. Therefore, to overcome these difficulties. Determine the sound of metal compounds in homogeneous materials asked manufacturing technology is very important. Combustion synthesis method is the use of non-uniform system of internal condensation reaction, solid-state synthesis of the units for the means. In such a use of compounds in the burning heat of formation elements in the same way as in Taiwan, because the macro does not produce molten material and synthetic material of Taiwan, it can be avoided and the reaction crucible materials,[link widoczny dla zalogowanych], preparation of homogeneous materials without gravity segregation . 13 Metallic Materials Technology Institute to the industrialization of TiNi intermetallic compound as the ultimate goal to study the elemental powders by combustion synthesis method. Route taken by the manufacturing process: Ti, Nj elements of a mixed powder of a burning platform beam into a hot isostatic pressing (} b P) handling a hot and cold plastic working of a product. In this method, the quality of each batch is lo0kg. This is the target output and manufacturing capacity of the production efficiency of process equipment design. First, take a certain percentage of the surface composition, Ni total of 100kg of raw materials powder fine kneading in dry conditions. Then use a special combustion device of the vacuum in the l0h combustion synthesis, powder synthesis of the elements of the station to ask for the metal object. Taiwan into the stainless steel container TiNj vacuum packaged, one cured by HIP sintering billets made. H is the relative density of population before treatment was 50% to 60% of the porous body, through the I The ingot-shaped whetstone that i smell of metal objects in the 1273K to Taiwan, forging, extrusion and rolling, processed into a variety of wire and sheet. Ling to l0% of the final processed,[link widoczny dla zalogowanych], the shape memory treatment,[link widoczny dla zalogowanych], so that the generation of flexible shape memory ltz. Combustion synthesis method, the process cleverly combined her operation, make composite materials in the defense of impurities lower than the original. But the burning question sets of metal compounds into the legal system, in order to reduce the composition of the impurities, the choice of the original Section powder is very important for TiNi, the impurity content on the pulp strength and plastic deformation has great influence on shape memory properties . This method produced TjNj excellent performance of shape memory alloy products, products made with traditional methods equal or better. Currently, these products have been used to correct tooth form from the elastic fibers of silk, glasses frame. Logo freeze warning road in terms of yield growth. Combustion synthesis of TiNi material except metal question of Taiwan, and vacuum as I Alexandra Rao Results of material use, but also used as a plasma rotating electrode rotating electrode,[link widoczny dla zalogowanych], manufacturing high-lao spherical powder spray welding as the HIP and use of raw materials . Practice Certificate Qi, Japan Institute of Metal Technology development is the manufacture of metal combustion synthesis of compounds with a very powerful tool. It is expected it to be contributed to the metal A practical matter of Taiwan's most promising manufacturing method. (XM)
