  • Patent number: 6368429
    Abstract: The present invention relates to a method for producing tubing products from binary and multicomponent zircon alloys, consisting in obtaining from an ingot previously submitted to a beta distortion process p source preparation, hot forming said source preparation at the subsistence temperature of zirconium alpha+beta to get a tubular blank hardenning the latter at a temperature higher by 30 to 60° to the temperature at which the alloy passes from an intermediary state zirconium alpha+beta to the beta state of zirconium, mechanically processing, following by a tempering process at the subsistence temperature of alpha zirconium until the finished product is obtained, the cold distortion of the tubular product being effected with the following global stretching: &mgr;&Sgr;>100 for the finished products and &mgr;&Sgr;<50 for the TREX or SUPER TREX-type semi-finished tubular products, whereby at the first stage of the cold distortion the stretching &mgr;<2.
