Abstract The commercial attractiveness of rolls with greater resistance to wear and fatigue damage is substantial. providing reduced rol領(lǐng) mil down times. increased roll life. reduced product surface defects and improved stock gauge tolerances Relatively little is known about 1&' wear mechanisms of these materials which limit the useful life of cold rol領(lǐng) mill work rolls.
