Fatigue crack growth behavior has been examined in a particulate titanium diboride (TiB2)–reinforced iron-based composite that had been produced via a mechanical alloying process. Comparison with equivalent unreinforced material indicated that fatigue crack growth resistance in the composite was superior to monolithic matrix material in the near-threshold regime. The composite exhibited relativ...

PURPOSE The objective of this study was to investigate the effect of surface treatments on microtensile bond strengths (MTBSs) of two types of indirect resin composites bonded to a conventional direct resin composite. MATERIALS AND METHODS Indirect resin composite blocks of Ceramage and SR Nexco were prepared in a plastic mold having a dimension of 10 × 10 × 4 mm. These composite blocks were ...

techniques of severe plastic deformation have been successfully used for the production of novel metallic microstructures. among different types of these techniques, accumulative roll bonding (arb) has been extensively used to produce multi-layered composites. in the present study, a new manufacturing process for cu/ni- 1vol% fe3o4 composites was developed by using copper and nickel sheets toge...

this article gives an approach to predict the springbackward phenomena during post solidification cooling in a functionally graded hybrid composite cylindrical shell with transverse isotropic structure. here the material properties are considered to be given with a general parabolic power-law function. during theoretical analysis, appropriate transform is introduced in the equilibrium equation ...

BACKGROUND This article aims to investigate current perceptions of beauty of the general public and physicians without a specialization in plastic surgery performing aesthetic procedures. METHODS A cross-sectional and interviewing questionnaire was administered to 290 people in Seoul, South Korea in September 2015. The questionnaire addressed three issues: general attitudes about plastic surg...
