IMPROVEMENT OF FATIGUE STRENGTH OF CAR AXLES BY WARM SURFACE ROLLING AND AGE HARDENING AFTER COLD SURFACE ROLLING

With increase in train speeds, the fatigue strength of car axles must be increased. Japanese National Railways has been experimenting with increased resistance to fatigue cracks in the wheel-set areas of normalized axles by two methods: Warm Surface Rolling and Age Hardening After Cold Surface Rolling. Both methods were found effective in increasing axle fatigue strength.
