摘要： By implementing that: an S content in designing steel composition is reduced; a stretch reducer in sizing rolling is configured to have a rolling roll with a caliber profile closer to a true circle; and a pipe is made to have an appropriate profile ratio (ratio of the radius of the inner surface curvature to the average inside radius) at a site corresponding to an edge portion, or even when the inner surface wrinkle is generated on a hollow pipe subjected to sizing rolling, by securing a predetermined wall thickness reduction rate in subsequent cold drawing, the pipe can be applied as an automotive drive shaft and can be used as a hollow member high in strength and excellent in fatigue strength and best suitable for reducing the weight and ensuring silence. Consequently, an automotive drive shaft can be produced at low production cost and efficiently.

摘要： A bulk silicon carbide single crystal of good crystalline quality which includes a minimized number of structural defects and is free from micropipe defects can be produced by crystal growth in a melt of an alloy comprising Si, C, and M (wherein M is either Mn or Ti) and having an atomic ratio between Si and M in which the value of x, when expressed as Si1-xMix, is 0.1 ≤x≤0.7 in the case where M is Mn or 0.1 ≤x≤0.25 in the case where M is Ti at a temperature of the melt which is below 2000 DEG C. The C component is preferably supplied into the melt by dissolution of a graphite crucible which contains the melt such that the melt is free from undissolved C. The crystal growth can be performed either by cooling the melt after a seed substrate is immersed in the melt or by forming a temperature gradient in the melt and immersing a seed substrate in a lower temperature region of the temperature gradient.
