Material properties of diamond. Burns above 700 °C in air. Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. It is a crystal that is transparent to opaque and which is generally isotropic (no or very weak birefringence ).
Rockwell scale. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [ 1] There are different scales, denoted by a single letter, that use different loads ...
Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. Diamond demonstrates both high thermal conductivity and electrically insulating properties, and much attention has been put into finding practical applications of this material. However, diamond has several limitations for mass industrial ...
Grinding wheel. Grinding wheels are wheels that contain abrasive compounds for grinding and abrasive machining operations. Such wheels are also used in grinding machines . The wheels are generally made with composite material. This consists of coarse-particle aggregate pressed and bonded together by a cementing matrix (called the bond in ...
Diamond turning is turning using a cutting tool with a diamond tip. It is a process of mechanical machining of precision elements using lathes or derivative machine tools (e.g., turn-mills, rotary transfers) equipped with natural or synthetic diamond-tipped tool bits. The term single-point diamond turning ( SPDT) is sometimes applied, although ...
Ryder is very particular — well, he's very particular about one thing really. His bedtime. Don't mess with his nightly routine. The dog had to have a "strongly worded conversation" with his ...
A diverging diamond interchange ( DDI ), also called a double crossover diamond interchange ( DCD ), [ 1][ 2] is a subset of diamond interchange in which the opposing directions of travel on the non- freeway road cross each other on either side of the interchange so that traffic crossing the freeway on the overpass or underpass is operating on ...
Psyllium husk is a type of fiber—specifically, soluble fiber, which means it attracts water and turns to gel when it’s being digested, explains Jessica Cording, R.D., author of The Little Book ...
