Sub-zero treatments are supplementary process to conventional heat treatment, since it converts the retained austenite into martensite which is remained after heat treatment and due to martensite formation is an increase in wear resistance. In the work presented the results of the experimental researches regarding the wear resistance of steels with the concentration of 0.54 to 0.57%C; 0.75 to 0.78%C and 0.92 to 0.97%C, sintered at a temperature of 1150 oC and 1250oC for 60 min, oil quenched and cooled sub-zero at 173K for 60 min, respectively 120 min..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
