Structuroscopy of Coils after High-Temperature Mechanical Treatment on the Basis of Measurements of Rayleigh Waves Velocity
For the Steamrollers manufacture of spring springs of rolling stock (wagons, locomotives, cars), bars made of spring steels are used.With high-temperature machining, when winding springs and quenching them, there is a difference in the cooling rates of the inner and outer sides of the spring coils, which leads to a difference in the structural stat
