    摘要： Zur Bestimmung der Härte eines pressgehärteten Bauteils, das auf eine vorbestimmte Temperatur erwärmt und anschließend in einer Presse umgeformt und abgekühlt wird, werden die Oberflächentemperaturen des Bauteils unmittelbar nach der Abkühlung in unterschiedlichen Oberflächenbereichen erfasst und dann die Temperaturdaten einer Auswerteeinrichtung zugeführt, in der sie in Daten bezüglich der IST-Härte des Bauteils umgerechnet und mit SOLL-Härten verglichen. Wenn die IST-Härte des Bauteils von der SOLL-Härte um mehr als ein vorgegebener Toleranzwert abweicht, werden die Betriebsparameter der Presse geändert und/oder des Bauteils ausgeschleust.

    摘要： A measurement apparatus for carrying out an indentation creep test on a specimen, including a measurement control apparatus that includes a load measurement device configured to measure a load, a constant-load compression device configured to compress a tip of a transparent indenter to a surface of the specimen, and an image capturing device configured to optically capture an image including a contact area portion which is a part of the specimen to which the load is applied by the constant-load compression device; and including an information processing apparatus that includes an image analysis unit configured to analyze a contact area, and a physical property value calculation unit. The physical property value calculation unit includes a first calculation unit configured to subtract a plastic contact area to be obtained analytically from the contact area so as to calculate a viscoelastic contact area, a second calculation unit configured to calculate contact stress based on the viscoelastic contact area and the constant load value, and a third calculation unit configured to calculate a contact strain rate based on the viscoelastic contact area, the physical property value calculation unit being configured to conduct linear regression with respect to a plot of a logarithmic value of the contact stress and a logarithmic value of the contact strain rate so as to determine a creep index n and creep constant k. Accordingly, it is possible to evaluate a creep index n and a creep constant k, which are creep physical property values, simultaneously, easily, and quickly.
