摘要： Wave-like concaves/convexes are formed on respective flat surfaces of a heat exchange tube, such that crest lines of continuing V shapes in a horizontal direction and trough lines of continuing V shapes in the horizontal direction are alternately arranged and that bends of the V shapes form curve lines. This configuration reduces the stress concentration at the bends in a press-forming process, compared with a configuration that crest lines and trough lines have bends formed in a shape of continuing sharply-angled V shapes in the horizontal direction. As a result, this configuration increases the yield in the press-forming process at a fixed amplitude of the wave-like concaves/convexes and increases the amplitude of the wave-like concaves/convexes at a fixed yield in the press-forming process.

摘要： A method for predicting a martensitic transformation rate and a method for setting processing conditions capable of improving the accuracy of a prediction of a martensitic transformation rate when a steel material is subjected to deformation processing as well as to heat treatment are provided. A method for predicting a martensitic transformation rate according to an embodiment includes predicting a rate of a transformation to a martensitic phase that appears when a steel material is subjected to deformation processing as well as to heat treatment in which a temperature of the steel material is changed, in which a martensitic transformation rate Vm is calculated by using a prediction formula, the method further including identifying parameters m and n of the prediction formula, and calculating the martensitic transformation rate at a predetermined temperature and a predetermined strain rate by using the prediction formula into which the identified parameters are substituted.

摘要： Provided is a method of manufacturing an oriented steel plate having two or more regions in each of which a crystal orientation is arranged in a specific direction. In the method, at least two single crystal steels are brought into contact with a principal surface of a polycrystalline steel plate so that crystal orientations of the single crystal steels and are arranged in different directions, and heat treatment of the single crystal steels and the polycrystalline steel plate is performed. This causes crystal growth following the crystal orientations of the single crystal steels to occur in the polycrystalline steel plate. Then, two or more single crystal steels having different crystal orientations are formed in the polycrystalline steel plate.

摘要： An electrical wire includes an aluminum element wire that has an aluminum base material and carbon nanotubes dispersed in the aluminum base material, in which the aluminum element wire has an electrical conductivity of 62% IACS or more and a tensile strength of 130 MPa or more. The aluminum base material is a polycrystalk having a plurality of aluminum crystal grains. Further, a carbon nanotube conductive path, which is composed of the carbon nanotube, and forms a conductive path allowing electricity to conduct therethrough in a longitudinal direction of the aluminum element wire by being present in a part of grain boundaries between the plurality of aluminum crystal grains in a transverse cross section of the aluminum base material, and being present along the longitudinal direction of the aluminum element wire, is formed in the aluminum base material.

摘要： A carbon nanotube composite material (1) includes a metal base material (10) and carbon nanotube electrically-conductive path portions (20). The metal base material (10) is made from a polycrystalline substance in which a plurality of rod-shaped metal crystal grains (11) are oriented in a direction. The carbon nanotube electrically-conductive path portions (20) are made from doped carbon nanotubes having a dopant, existing in parts of grain boundaries (15) between the rod-shaped metal crystal grains (11) in a cross section of the metal base material (10), and forming an electrically-conductive path which is electrically conductive in a longitudinal direction of the metal base material (10), by existing along the longitudinal direction (L).
