Abstract

PURPOSE: To make occurrence of surface flaws on a Ti strip difficult by continuously annealing the cold rolled Ti strip in an Ar atmosphere contg. a very small amount of oxygen or a very small amount of oxygen and a specified amount of nitrogen to form a colorless surface hardened layer.
CONSTITUTION: When a cold rolled Ti or Ti alloy strip is continuously annealed in a gas atmosphere, the heating temp. is adjusted to 750W850°C, and Ar contg. 30W200ppm O2 or Ar contg. 30W200ppm O2 and 0.5W10vol% N2 is used as the atmospheric gas. Thus, oxygen or oxygen an nitrogen are dissolved in a surface part of the strip after the annealing without coloring the surface to form a hardened layer, and this surface hardened layer protects the strip from surface flaws.
