NICOLAE Avram: Informational
system for environmental risk assessment from iron & steel industry Metalurgia (57) 2005, nr. 8, p. 5 The paper presents an informational system
(based on databases) for environmental risk assessment from iron & steel
industry. The databases realized (for emissions, imissions, technological
wastes, waste waters, hazardous compounds and accidents) are new at the
national level. These were transferred to, and used by the Environmental
Protection Department of the SC ISPAT SIDEX SA D.C.: 66.015.24 key words: nanofluids Agop Marcel, Mamut Eden,

Petrică: a theoretical approach of the heat
transfer in nanofluids Metalurgia (57) 2005, nr. 8, p. 13 A theoretical approach of the heat
transport in nanofluid using the scale relativity is elaborated. In such
context, one shows that the nP/L interface self-structurates as a non-linear
Toda vortex lattice and one
specifies some of its properties (intrinsic anisotropy and the phononic
spectrum components). In our opinion, the heat transfer in nanofluid is given
by means of the thermal anyons. D.C.: 539.374 Key words: flow stress, strain rate, strain rate sensitivity exponent, grain-boundary sliding, accommodation processes. Ana-Luciana Rus: Mechanism of superplastic deformation and
phenomenological relations micrograin superplasticty Metalurgia (57) 2005, nr. 8, p. 32 Over the last two decades, much attention |
has been devoted to examining and attempting to explain
the physical mechanisms which occur during superplastic deformation. A
detailed understanding of these mechanisms is a prerequisite for extension of
research in the superplasticity phenomenon either to new advanced materials
or to new testing conditions, which are more favorable for the successful
utilization of superplasticity in industrial forming operations. The paper
reviews briefly the mechanism of superplastic deformation and the
phenomenological relatios micrograin superplasticity. Key words: concurrent engineering, design for quality,
Taguchis method mariana pop: Designing
for quality, goal of concurent engineereing Metalurgia
(57) 2005, nr. 8, p. 38 Concurrent
Engineering is a systematic approach to the integrated, concurrent design of
products and their related processes, including manufacturing and support. It
is known as
simultaneous engineering, concurrent design, integrated development of products,
team design, total engineering leading to reduce the time-to-market. The aim of
this paper its o present some aspects regarding the design for quality,
especially the method of Genichi Taguchi . |
