TITANIUM ALLOY WITH EXCELLENT RESISTANT INTERGRANULAR CORROSION CAPABLE OF MINIMIZING CORROSION SPEED UNDER A SPECIAL ENVIRONMENT VULNERABLE TO INTERGRANULAR CORROSION

摘要

PURPOSE: Titanium alloy with excellent resistant intergranular corrosion is provided to minimize resistant intergranular corrosion under a special environment by properly controlling the final annealing condition after rolling Ti-Ni-Pd-Ru-Cr alloy.;CONSTITUTION: Titanium alloy with excellent resistant intergranular corrosion comprises Ni of 0.35~0.55 weight%, Pd of 0.01~0.02 weight%, Ru of 0.02~0.04 weight%, Cr of 0.1~0.2 weight%, titanium and other inevitable impurities. The titanium alloy forms rows in a rolling direction and the rows are formed side by side in a width direction, when a form locally containing Ni of 10 times the average content of Ni becomes another form with abundant Ni. When a form locally containing Ni of 10 times the average content of Ni becomes another form with abundant Ni, the form contains Ti2Ni.;COPYRIGHT KIPO 2012
