Effects of Access Cavity Design on the Shaping Ability and Dentine Thickness Following Canal Preparation Using XP‐Endo Shaper or Reciproc

open access: yesAustralian 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 ...

Multiaxial Creep Rupture Life Evaluation for Austenitic Stainless Steels Using Weld‐Type Miniature Cruciform Specimen

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT A multiaxial creep testing technique using a weld‐type miniature cruciform specimen was developed to evaluate the creep properties and rupture life of Super 304H austenitic stainless steel at 973 K (700°C). The cruciform specimen was designed to achieve a plane stress state and overcome material dimensional limitations.

Cyclic Plastic Material Behavior of Novel Austenitic (C + N) Steel Additively Manufactured by PBF‐LB/M

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The newly introduced high manganese high strength (C + N) steel Printdur HSA was developed for the additive manufacturing process PBF‐LB/M. It consists of a fully austenitic grain structure. This study aims to evaluate the cyclic plastic material behavior of this (C + N) steel.
