Theory and significance of retained austenite in steels
, 2019 The processes leading to the retention of small quantities of austenite following the bainite and martensite phase transformations have been examined, together with the influence of retained austenite on the properties of low alloy steels. It was found that the upper and lower bainite transformations are separate reactions, although both involve a ...

Australian Endodontic Journal, EarlyView.ABSTRACT This study compared the shaping ability and remaining dentine thickness in mandibular molars prepared with traditional (TradAC) or ultraconservative (UltraAC) access cavities using Reciproc or XP‐endo Shaper instruments. Thirty‐two molars were scanned with micro‐CT before and after preparation to assess canal surface, volume, untouched walls ...

Evaluation of Creep Life and Damage for AISI 304 Under Combined Tension/Torsion Multiaxial Loading
Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT In the present study, to investigate the effects of temperature and principal stress ratio on the multiaxial creep rupture time of AISI 304 stainless steel, creep tests were conducted under various principal stress ratios at 650°C and 700°C.
