WHEELSETS UNDER CURRENT CONDITIONS
The importance of heat-treatment techniques and their effect on wheels carrying increasing loads at faster speeds were discussed at the three-day Third International Wheelset Conference. Most speakers accepted the martensite theory without advancing reasoned criticism of the "plastic-strain cycle" theory or attempting to discuss a cardinal point that thermal cracking could occur at hot-spot temperatures below the transition temperature, so that no martensite was produced. Development of resilient wheels was considered somewhat slanted in favour of the screwless, single-ring type. Performance of single-ring wheels in which the rubber was both in shear and compression was based on the assessment of the desired load-deflection characteristics in the radial, tangential and axial directions.
