OBJECTIVE To evaluate the quantitative effects on torque expression of varying the slot size of stainless steel orthodontic brackets and the dimension of stainless steel wire, and to analyze the limitations of the experimental methods used. MATERIALS AND METHODS In vitro studies measuring torque expression in conventional and self-ligating stainless steel brackets with a torque-measuring devi...

TiN and Ti2O3 are the predominant inclusion types in Ti-alloyed ferritic chromium stainless steels. In order to ensure the required steel cleanness level, an effective removal of such inclusions in the slag during secondary metallurgy is essential. This inclusion removal predominantly takes place via dissolution of the inclusion in the slag. The dissolution behavior of TiN and Ti2O3 in CaO-SiO2...

Purpose: The aim of the paper is to design heat treatment conditions of dual-phase steel and to determine their influence on the structure and mechanical properties of steel. Design/methodology/approach: The heat treatment of the C-Mn steel in order to obtain a dual-phase ferritic – martensitic structure of desirable phase fractions was realized. To investigate the influence of heat treatment p...

CRA-lined pipelines, i.e. pipes with an inner pipe of a corrosion resistant alloy inside of a ferritic steel pipe carrying the hoop stress, pose a challenge to inspect with conventional in-line inspection technologies. Existing UT technology is not able to inspect through the interface of a CRA and a ferritic steel component. Additionally, current MFL technology is not able to sufficiently magn...
