THE INFLUENCE OF BRAZING TEMPERATURE ON THE METALLOGRAPHIC MICROSTRUCTURE OF THE BONDED WELD
No full textSince it was determined that as a result of fatigue on the brazed joints, the breakage occurs in thefiller material or in its immediate vicinity (Z.I.T.M.), it is necessary to study the phenomenon in themicrostructure. The experiments have been made on alloys 3L59 samples, using as filler material the aluminumalloy L103. The brazing was made by gluing, overlapping nonstandard sample
OBTAINING COMPOSITE MATERIALS OF THE POLYMER-ALUMINUM TYPE BY GLUING USING BICOMPONENT ADHESIVES
No full textTHE INFLUENCE OF TEMPERATURE ON THE ALUMINUM ALLOYS
No full textIn the technical literature are some correlations with reference to the influence of brazing temperatureon aluminum alloys, but there is not a diagram generally accepted.This paper aims to establish a direct correlation between the mechanical properties and the retentiontime of the brazing temperature. The experiments were applied on samples of aluminum alloy 3L59. Theretention time varies from T1 = 10 minutes to T3 = 30 minute
ALGORITHM TO CHOOSE ENERGY GENERATION MULTIPLE ROLE STATION
No full textThis paper proposes an algorithm that is based on a complex analysis method that is used for
choosing the configuration of a power station. The station generates electric energy and hydrogen, and serves a
"green" highway. The elements that need to be considered are: energy efficiency, location, availability of
primary energy sources in the area, investment cost, workforce, environmental impact, compatibility with
existing systems, meantime between failure
COMPARATION BETWEEN NONDESTRUCTIVE TESTING METHODS FOR THE ALUMINIUM BRAZED PIECES
No full textPresented paper refers to different control methods used in aluminium brazed joining because of
possible defects. Low joining complexity permits exact damages position in relation with materials geometry
FATIGUE CURVES FOR ALUMINIUM BRAZED AREAS
No full textAn important factor for the quality of joints is the brazed area. The fatigue check occupies a majorposition among many test procedures and methods, especially by the joining technologies. The results ofprocessing the fatigue data experiments for aluminium brazed probes are used to find the regression functionand the response surface methodolog
Innovation Management: The Past, Present and Future of the Market
No full textThe paper presents aspects of innovation management, important issues based on literature and studies by Boston Consulting Group (USA). The case study lays on the survey made by BCG on 1500 subjects all over the world from all the industry sectors. The paper studies the importance of innovation management and makes predictions for research and development expenditure for Top4, Apple, Google, Tesla Motors and Microsoft, without taking into account rank number 5, Samsung, because the official income statement was in Korean Won
Tradiție și actualitate în sociologia academică ieșeană
No full textThe text aims at emphasizing the tradition and evolution of the academic sociology of Iaşi, tracking its origins. Thus, we tried to focus upon the emblematic personalities who contributed to the development of sociology in Iaşi (Constantin Dimitrescu-Iași, Constantin Leonardescu, Dimitrie Gusti, Petre Andrei, Vasile Miftode), dwelling on the ideas and themes outlined or developed by them at the Iaşi school of sociology. Our approach went even further, purporting to emphasize the professional competences and publications of the new generation of sociological thinkers in Iaşi, especially as authors of volumes. This approach, which is part of a history of sociology in Iaşi, shows that sociology at „Alexandru Ioan Cuza” University has had an outstanding evolution and a unique tradition
„WASHING HEAD HOUSING” 3D PRINTING FROM FA 100 DRILLING INSTALLATION, USING PETG FILAMENT
No full textIn this work, we proposed 3D printing additive manufacturing, using Fused
Deposition Modeling technology for the washing head housing, which is common for water
drilling installations FA100, FA125, FH150 and FG40. Due to the common use of this washing
head for the water drilling installations FA100, FA125, FH150 and FG40, we use the generic
name "FA100 Washing Head". We use 3D printing technology because, on the one hand, it is
technically possible to make the part and on the other hand, for economic reasons. It is
approximately ten times cheaper to make the part through 3D printing than through conventional
technologie
