Nanograined metals and alloys, whose grain size is less than 100 nm, exhibit extremely high strength and high ductility, possessing excellent mechanical properties. Nanograined materials, however, ...

The limitation of nanograined materials is their strong tendency to coarsen at elevated temperatures. As grain size decreases into the nanoscale, grain coarsening occurs at much lower temperatures, as ...

Twenty-two grain sorghum genotypes [Sorghum bicolor (L.) Moench] were evaluated for yielding ability under five varied treatments of water stress during 1987 and 1988 seasons. The relative stability ...
