Medium Mn lightweight steels with a relatively higher content of 9–12 wt% have been actively developed recently to meet the demands crashworthiness and vehicles. In this study, combined intensive quenching (IQ) deep cryogenic treatment (DCT) was first proposed achieve microstructural homogeneity as well final strength–ductility synergy medium segregation bands, together comparison conventional ...

INTRODUCTION Cyclic fatigue is the common reason for breakage of rotary instruments. This study was conducted to evaluate the effect of cryogenic treatment (CT) in improving the resistance to cyclic fatigue of endodontic rotary instruments. METHODS AND MATERIALS In this in vitro study, 20 RaCe and 20 Mtwo files were randomly divided into two groups of negative control and CT. CT files were st...
