Ioan: Researches by
physical modeling regarding the influence of the construction of the feeders
on the retention of the inclusions inside runner of pouring gates Metalurgia
International (vol. XI), no.2, 2006, p. 5 The paper presents the results of some experimental
study made by physical modeling. The study refers to the influence of the
location of the feeders related to the runner on the retention of the
inclusions inside the pouring gates. The objects of the study were the
pouring gates with four feeders on the runner, considering four types of the
construction of the feeder. It has been made determinations in condition of
starting pouring (starting work condition) and in stationary tap condition
(permanent- the pouring gate filled by liquid). The researches concluded that
the upper lateral location of the feeders related to the runner ensured a
better retention of the inclusions inside the pouring gates. D.C.: 669.71; 669.782; 669.24 Key words: thermal diffusivity; aluminum matrix alloys;
composites Căliman Radu: Influence of Al2O3 or ZrO2
addition on the AlNi and AlSi alloys Metalurgia
International (vol. XI), no.2, 2006, p.16 Different metal/ceramic composites (Al3Ni, Al6Ni,
Al9Ni) reinforced with Al2O3 or ZrO2 will be
investigated. In all the composites a-Al did not nucleate on the reinforcement
particulates. The particulates were generally observed to be located in the
last freezing regions regardless of matrix alloy, particulate type or size.
The reason for that was the mismatch in the thermal diffusivity between the
ceramic particulates and matrix alloys. D.C.: 66-976. GHIMBĂŞEANU
Ioan: Simulation a LM135/LM235/LM335 precision temperature
sensor Metalurgia
International (vol. XI), no.2, 2006, p. 19 The main
advantage of a measurement instrumentation, based on the technique of
calculation named virtual instrumentation |
compared to a classic measurement instrument lies on the fact that the
virtual instrumentation can be easily transformed through programming. The paper presents the simulation of a LM135/LM235/LM335
precision temperature sensor. This simulation is done through a LabVIEW
graphic language. D.C.: 622.73 Key words: foundry equipment, crusher Chichernea
Metalurgia International (vol. XI),
no.2, 2006, p. 24 A numerical method was employed in order to establish the calculation
of kinematic parameter of a crusher. D.C.: 536.7 Key words: copper, activity, activity coefficient, atomic
ratio, oxygen, interaction coefficient Hotea Vasile, Mariana Zsigmond, Iepure Gheorghe, Elena Pop: Liquidus equilibria and
solution thermodynamics an copper-oxygen Metalurgia
International (vol. XI), no.2, 2006, p. 26 This work
presents the study of some thermodynamic properties of the Cu-O system, which
represent the base of several technological processes in the pyrometallurgy
of copper. The
research have been determined several thermodynamic measurements activity and
activity coefficient of oxygen in liquid copper-oxygen function on the
temperature and oxygen concentration influence on them. The experimental results have been
compared to various thermodynamic models reference to metallurgical melting
for alloys and discovery of some structural information on the melting in the
studied system. |
