The micro-hardness of enamel and dentin.
THE hardness of enamel and dentin has been determined by a variety of methods including abrasion," 2 pendulum,' scratch,4-7 and indentation" teehnics. Since the hardness of enamel and dentin has been shown to have considerable local variations, the methods using a microscratch or microindentation have been preferred. One of the more common types is the Knoop diamond indenter14 which has been us...
متن کاملAnalysis of Surface Roughness and Micro-hardness in Roller Burnishing of Aluminum Alloy 6061
Burnishing is a chip-less finishing process, in which a hard roller or ball presses the surface layer of part to perform plastic deformation in the surface layer and produce improved finish, enhanced hardness and compressive residual stresses on the surface of special materials such as Aluminum and Brass. In the following research, the effect of input parameters such as feed rate, cutting speed...
متن کاملEffect of the asymmetrical rolling process on the micro hardness and microstructure of brass wire
Current experimental investigation deals with the effects of asymmetrical rolling parameters on the inhomogeneity, microstructure, mechanical, and geometrical properties of rolled brass wire. Toward this end, a roll machine with three different roll radii ratios was set up. The asymmetrical conditions are arranged using three different sets of rolls with different diameters that result into dif...

متن کاملSelection of Arc Welding Parameters of Micro Alloyed Hsla Steel
Like all steel types, HSLA requires a definition and strict practical adherence to welding parameters in order to achieve the required weld quality. Different sources offer a varying array of welding parameters. Although their hierarchical importance can be disputed, their principal definition and practical adherence are prerequisites for the quality of welded joints 1,2 . The analysis of earli...
