NITROGEN-CONTAINING SUPER HEAT RESISTANT LIGHT METAL MATERIAL AND NITROGEN-CONTAINING ULTRAHIGH STRENGTH AND RIGIDITY LIGHT METAL MATERIAL AND THEIR PRODUCTION

摘要

PURPOSE: To produce a light metal increased in strength and rigidity and having superior heat resistance. ;CONSTITUTION: Aluminum or magnesium is immersed into a cyanide salt bath containing pyrosol of titanium or zirconium and then electrolysis is performed, thereby, nitrogen is allowed to penetrate and diffuse rapidly into aluminum or magnesium. By this method, the ultrahigh strength and rigidity or super heat resistant light metal material is made to be obtained.;COPYRIGHT: (C)1996,JPO
