Information × Registration Number 0201U001508, 0198U004482 , R & D reports Title Development of the bases of maintenance of the requirements of the international standards to mechanical properties welded of pipes and bend of structures on the basis of researches hardening of a metal at complex large plastic deformations. popup.stage_title Head Zil'berg Yurij Volodymyrovych, Registration Date 08-02-2001 Organization National Metallurgical Academy of Ukraine popup.description2 Changes of mechanical properties carbon steel in processes moilding, bend, opposite direction of a bend in comparison with rolled stock of a metal are investigated. Influence of complex kinds of deformation to mechanical properties is determined. Оценгены of a feature in behaviour of a metal. The requirements to maintenance of export welded of pipes are developed. On the basis of conducted researches change of a limit of fluidity have become to her oppsite direction of a bend a technique accoun of capacity of a engine sizing rolling mill is developed at moulding sguare of a pipe 80 х80 mm.
