The first evidence for accelerated diffusion in polycrystalline materials was obtained with the use of tracers [6-9].
Stress effect For GB heterodiffusion and self-diffusion in multicomponent (at least, impure) materials the significant difference from the Fisher linearizing coordinates is observed.
Only ∇p can be an additional driving force in deformed materials.
The data obtained for materials of different purities demonstrate that the diffusion in the metal of higher purity is faster.

Study of Low-Grade Nickel Laterite Processing Using Palm Shell Charcoal as Reductant Bambang Suharno1,a, Nolzha Primadha Ilman1,b, Achmad Shofi2,c, Deni Ferdian1,d, Fajar Nurjaman3,e* 1Department of Metallurgy and Materials Engineering, Faculty of Engineering, Universitas Indonesia, Depok, Indonesia 2Public Works and Spatial Planning, Rembang Regency,Central Java, Indonesia 3Research Unit for Mineral Technology, Indonesian Institute of Sciences, Lampung, Indonesia asuharno@metal.ui.ac.id, bnolzhaprimadha@yahoo.co.id, cachmad.shofi@lipi.go.id, ddeni@metal.ui.ac.id, efajar.nurjaman@lipi.go.id Keywords: lateritic nickel ore, palm kernel shell charcoal, sodium sulfate, selective reduction Abstract.
Most of the industries used coal as non-renewable materials for reductant in nickel ore processing, which contributed to high acidic pollutant emission due to the sulfur dioxide and nitrogen oxide released into the air during the reduction/combustion process [12-13].
The study of biomass as a renewable material for reductant in nickel ore processing should be investigated for lowering the pollutant emission [14].

Introduction Industrial corporations comprise many different disciplines from mechanical engineering to industrial engineering up to computer science.
Material flow: Just as between the production areas, optimal material flow should be found for the working stations (Figure 13 b)
For example, bottlenecks in the material flow in relation to the workload of the machines can easily be noticed and associated adjustments can be realized (see Fig. 14 c).
