Manganese is not a part of chlorophyll. The symptoms of manganese deficiency are remarkably similar to magnesium because manganese is involved in photosynthesis. Leaves become yellow and there is also interveinal chlorosis. However, manganese is less mobile in a plant than magnesium, so that the symptoms of deficiency appear first on young leaves.

Isobel Mc Dougall, in Handbook of Ferroalloys, 2013. 4.2.2 Sintering of Manganese Ore. The sintering process employed for manganese ore and the siliceous ores used to produce silicomanganese results in partial reduction of MnO 2, Mn 2 O 3, and Mn 3 O 4 in the ore to MnO by reaction with carbon in addition to agglomerating the fine ore and coke. New technology also utilizes addition of fluxes ...

The original austenitic manganese steel, containing about 1.2% C and 12% Mn, was invented by Sir Robert Hadfield in 1882. Hadfield`s steel was unique in that it combined high toughness and ductility with high work-hardening capacity and, usually, good resistance to wear. Many variations of the original austenitic manganese steel have been ...

1. Introduction. High-manganese steel, as a traditional wear-resistant steel, is extensively used in the mining, machinery, and railway industries, which is attributed to its excellent work-hardening capacity [1,2].The excellent wear-resistance is associated with the formation of a work-hardening layer under high-impact-energy conditions, which increases the hardness of a worn surface to be 2 ...

In this study, a novel high-manganese steel (HMS) was borided at 850, 900 and 950 °C for 2, 4, and 6 h by the pack boriding process. Contrary to previous literature, borided HMS uncommonly exhibited saw-tooth morphology like low alloy steels, and manganese enhanced the boron diffusion. Another striking analysis is that the "egg-shell effect" did not occur.

The modern name "manganese" was derived from the 16 th century name for manganese dioxide, manganesum. The pigments from several colored manganese oxides, such as manganese dioxide, have been used by men since the Stone Age, as is the case in the Gargas cave paintings. These have been dated as 24,000 to 30,000 years old.
