摘要： In a method of measuring optical characteristics of a component in a liquid impregnated in a porous material with no affection by the porous material, a light beam having an absorbable wavelength which is absorbed by the component in the liquid and a light beam having a wavelength which is longer than the absorbable wavelength are projected to the porous material, and a quantity of light having the wavelength which is absorbed by the component in the liquid is compensated by a quantity of transmitted light having the wavelength longer than the absorbable wavelength.

摘要： A twin-roll continuous casting method that controls occurrence of casting defects in a center part of plate thickness, for Al—Mg series aluminum alloy, a material featuring a wide temperature range for solid and liquid phases coexistence. In the method of manufacturing an Al—Mg series aluminum alloy cast plate, the plate contains Mg in a predetermined amount and has a relatively thick plate size, while casting is performed by a twin-roll type continuous casting method. Twin rolls have a roll diameter, and the rolls have a circumferential velocity. The circumferential length from points where molten metal starts contact with the rolls to kiss points is a solidification distance, and the roll gap at the kiss points is equal to the thickness of the cast plate. Specific relations among the above factors are maintained, and the continuous casting operation is carried out while satisfying such relations.

摘要： The present invention provides an aluminum alloy sheet for forming which is a high-Mg-content Al—Mg alloy sheet reduced in β-phase precipitation and improved in press formability. This aluminum alloy sheet for forming comprises an Al—Mg alloy containing 6.0-15.0 mass % Mg. In each of square regions, each side of which has the dimension of the whole sheet width (W), that are set in a surface of the alloy sheet, the concentration of Mg is measured at width-direction measurement points, Px, set at given intervals a and b respectively in the sheet-width direction and the sheet-length direction, and the average of the values of Mg concentration measured at the plurality of width-direction measurement points (Px) is taken as a width-direction average Mg concentration (Co). The concentration of Mg is measured at a plurality of thickness-direction measurement points (Py) set at a given interval in the sheet-thickness direction throughout the whole sheet thickness with respect to the plurality of width-direction measurement points (Px), and the average of the values of Mg concentration measured at the plurality of thickness-direction measurement points (Py) is taken as a thickness-direction average Mg concentration (Ci). The absolute value of the degree of regional Mg segregation (X) defined by the difference (Ci−Co) between the thickness-direction average Mg concentration (Ci) and the width-direction average Mg concentration (Co) is 0.5 mass % or less at most and is 0.1 mass % or less on average.
