The investigation and peculiarities of calculation of transport machine elements made of austempered ductile iron [PDF]

Transport, 2003
In this article the statical and cyclical strength investigations of austempered ductile cast iron (ADI) are presented. ADI material becomes more and more popular. Ductile iron is lighter than steel and its mechanical properties are better.
