Abstract
A method for producing cold rolled titanium strips having good surface quality. The cold rolling of a titanium strip is carried out under the conditions represented by the following formula: X.ltoreq.(48673/Y.sup.1.3283) where X is an average grain size (.mu.m) of the pre-cold rolled titanium strip and Y is a diameter (mm) of the roll for the cold rolling.
Claims5
A method for producing a cold-rolled titanium strip, comprising:
- predetermining the average grain size in micrometers of a pre-cold-rolled titanium strip, and
- cold-rolling said pre-cold-rolled titanium strip under the condition such that
- X.ltoreq.48673/.sub.Y 1.3283
- wherein X is the average grain size in micrometers of the pre-cold-rolled titanium strip, and
- Y is the diameter in millimeters of the rolls used for cold-rolling.
