Genesis and types of nickel laterites Lateritic nickel ores formed by intensive tropical weathering of olivine rich ultramafic rocks such as dunite peridotite and komatiite and their serpentinized derivatives serpentinite which consist largely of the magnesium silicate serpentine and contains approx % nickel This initial nickel content is strongly enriched in the course
· In this study Rockwell and Brinell hardness testing was used to examine material hardness These methods were chosen because they are easy to carry out relatively inexpensive and almost all sizes and shapes can be tested in which nickel hardness before and after centrifugal casting are identified and compared These tests enable the determination of
Nickel Alloys Nickel is a silvery white lustrous metal with a slight golden tinge Nickel is one of most common alloying elements About 65% of nickel production is used in stainless steels Because nickel does not form any carbide compounds in steel it remains in solution in the ferrite thus strengthening and toughening the ferrite phase
