The stainless steel is an alloy of Fe, Cr, and Ni mainly, and grain boundaries were very clearly observed.

Because of the high relative velocity between the wheel and the workpiece, the peclet number is large enough, and the conduction in the moving direction is negligible.
Therefore, all the fluid, grain and the workpiece can be assumed to be a semi- infinite body.

Introduction Yttrium and lanthanide sialon glass-ceramics have been investigated because of their improved refractoriness and mechanical properties compared with oxide glass-ceramics and because of their presence as grain boundary phases in silicon nitride based ceramics [1].

Because of grade of iron in ludwigite is very low, and there are some structure defects, the mineral grains of SiO2 and FeO contact with each other inevitably.
Small amount Si3N4 is produced resulted in exiting a large number of Fe.

By annealing at high temperature, the number of grain boundaries and dislocation would be significantly reduced and a lower HC was observed 6) .

A large number of rural surpluses inflexed into township enterprises.
Since 2004, within the range allowed by the WTO agricultural rules, our country gave direct subsidies to grains; gradually canceled of agricultural tax; cancel the special agricultural product tax, animal husbandry tax and livestock slaughter tax, gave farmers subsidies.
