Abstract:
PCT No. PCT/SE95/00749 Sec. 371 Date Apr. 17, 1997 Sec. 102(e) Date Apr. 17, 1997 PCT Filed Jun. 20, 1995 PCT Pub. No. WO95/35395 PCT Pub. Date Dec. 28, 1995The present invention relates to a method of manufacturing tubes of zirconium based alloys for usage in nuclear reactors. According to the invention one can achieve good resistance towards general corrosion, improved transversal creep strength and reduced irradiation induced growth by subjecting a beta -quenched tube a vacuum anneal in the alpha -phase range at a temperature and a time sufficient to obtain an annealing parameter value A in the range 3.4 x10-16 to 3.4 x10-13.
