The “reverse” stainless steel crown is a well-known method of correcting single tooth anterior crossbite (Fig 1). When an elongated preformed incisor stainless steel crown is luted with the lingual surface facing labially, the resulting slope contacts the opposing mandibular incisors and normal occlusal forces move the incisors out of crossbite relationship. The reverse crown method corrects “d...

This study has used the strain energy density (SED) approach to evaluate stress intensity factor (SIF) of cracked cruciform welded joints in Hardox 450 steel. A microstructural analysis was made steel which is composed refined and tempered low carbon martensite. The obtained results simulation will be compared with those provided by J-integral methode for different enriched zones contours based...

The 45-T Hybrid magnet will employ Cable-In-Conduit Conductor (CICC) technology for the windings of the Nb3Sn and NbTi coils. The conduit steel must retain high strength and fracture toughness at 4 K, following the Nb3Sn reaction heat treatment. The design requirements call for a 4 K yield strength exceeding 1000 MPa and a 4 K fracture toughness (KIc) greater than 110 MPa m -0.5. We report the ...

       This article describes the preparation and analysis of nano hydroxyapatite (HA) films on stainless steel 316L through sol-gel technique. The process started with preparation of a nitrate and phosphate sol. After aging the sol for 24 h at room temperature a SS316 substrate was dip-coated and heat-treated at 350 to 450 °C for different times in air. The coating phase and structure on subs...

This work reports the performance characteristics of custom thermocouples developed for use in elevated temperatures such as metal casting operations. The scope this research is limited to designed using pyrolytic graphite (PG) primary thermoelement connection with aluminum, copper, steel, and tungsten. Seebeck coefficients sensors were determined from experimental data after heating ~500 °C. C...

Superplastic bonding was performed using electrodeposited Ni and Ni-B to apply low-temperature diffusion of carbon steel. Electrodeposited were bonded at 450℃ in air a strain rate 1 × 10−4 s−1. The shear test measured the bond strength, maximum strength 69 MPa obtained. Since obtained is comparable that by steel 0.5Tm, it possible decrease temperature 0.4Tm applying this boning process. depende...
