Teodor Vasiu, Stefan Maksay: e valuation ofdisc-cylinderfrictioncouplewear in thecase ofconstantcontactrelativevelocities

Metalurgia (55) 2003, nr.2, p.5

The paper refers to the estimations we made on the wear rate of disc-cylinder coupling, made of Fc20, respectively OL37. the experiments were carried out at constant relative velocity and we considered as independent parameters the temperature in the contact zone and the corresponding pressing force. The conclusions we draw allow the appreciation of the normal functioning of the coupling under consideration and the results we obtained can be extended to the similar friction couplings, working in industrial conditions.

Metalurgia (55) 2003, nr.2, p.8

The industrial practice needs much economical materials. Such a case is presented in the paper, respectively the  magnetic  properties of an austenitic stainless steel,

economical by its alloying with manganese and with reduced content of nickel, with the possibility of being used in electrotechnics.

Starting from Entin-Zener relation regarding the pearlite lamells thickness variation depending on temperature, an application has been made taking into account the hypothesis of virtual and real pearlitic and bainitic prelamells, starting from austenite during the incubation period, taking in consideration a continuous diffusion transformation mechanism, an exponential relation is theoretically obtained for cementitic and pearlitic lamells. The Entin-Zener relation is also valid for bainitic lamells fragmentation sub-subunits thickness.
