    摘要： Disclosed herein is a thermoelectric material for intermediate- and low-temperature applications, in which any one or a mixture of two or more selected from among La, Sc and MM is added to a Ag-containing metallic thermoelectric material or semiconductor thermoelectric material. The thermoelectric material has a low thermal diffusivity, a high Seebeck coefficient, a low specific resistivity, a high power factor and a low thermal conductivity, and thus has a high dimensionless figure of merit, thus showing very excellent thermoelectric properties. The thermoelectric material provide thermoelectric sensors having high sensitivity and low noise and, in addition, is widely used as a thermoelectric material for intermediate- and low-temperature applications, because it shows excellent thermoelectric performance in the intermediate- and low-temperature range.

    摘要： The present invention relates to a process of the production of multilayered bulk materials. A plurality of constituting powders of a desired multilayered material are mixed at a predetermined ratio, particle of the powders being smaller than 100 .mu.m in size. The powder mixture is mechanically alloyed for a predetermined period of time by using a high-energy ball mill in an argon-filled glove box. The mechanically alloyed powder is loaded in a mold and is then hot-pressed under a uniaxial compressive pressure at a predetermined temperature, resulting in a composition having multilayered structure. The process according to the present invention provides an effective way of overcoming thickness limitations of conventional multilayered materials and enabling low-cost mass production of multilayered materials.

    摘要： Disclosed herein are a method for manufacturing a functional material for use in various industrial fields in which anisotropy or physical properties change according to height may be utilized, as well as a functional material manufactured thereby. The method includes the steps of: (1) mixing powders composed of the components of the functional material with a binder to prepare a mixed paste; (2) coating the mixed paste on a substrate, and then separating the coated material from the substrate, thus preparing a slice; (3) repeating step (2) to prepare a plurality of slices, and stacking the slices in a mold; and (4) pressing the stacked slices at a predetermined temperature and pressure. A multifunctional material, such as an anisotropic material having physical properties which change according to the direction of material, or a material having physical properties which change in a graduated manner according to height, may be manufactured in a simple and economical manner.

    摘要： The present invention relates to Fe—Cr—Ar type alloys with additions to improve workability thereof, strength, and heat resistance. The present Fe—Cr—Al alloy for electric resistance wires comprises a basic alloy added with only Be of below 0.01 wt % or with both Be and misch metal composed of rare earth elements wherein the basic alloy consists of a balance element of Fe, a Cr element of 12˜30 wt %, an Al element of 3˜14 wt %, a Zr element of 0.01˜1.5 wt %, and a Ti element of 0.001˜0.1 wt %. The present Fe—Cr—Al type alloys remarkably improve physical properties of Fe—Cr—Al ferritic alloys, especially, workability and mechanical properties, and heating characteristic.
