Each year the marketplace sees increasing demands for the analysis of hydrogen contained in various sample materials. It is now recognized that hydrogen analysis is crucial not only in the steel industry but also in the manufacture of such high purity metals as aluminum, copper, titanium and in the development of new alloys and new materials. To meet these demands, Horiba has developed and mark...

In this paper some recent advances in lightweight construction for modern shipbuilding are presented. Following a description of lightweight structures and their current use in shipbuilding, emphasis is put on naval applications of composites, and in particular on aspects related to cost benefit assessment and survivability. The following part reports on the use of adhesive bonding for superstr...

This paper concerns automotive parts located underneath the engine and in particular the engine oil pan. Classically made of stamped steel or cast aluminum, new developments have allowed the manufacture oil pans with polyamide 66 reinforced by 35% weight of short glass fiber. However, polyamides have some limitations and the most significant is their response to localized impact loading. The na...

Waste iron sulfate is produced in titanium dioxide manufacture and in steel pickling with sulfuric acid. Many processes have been proposed to use this waste as a source of chemicals or raw materials. The process developed here is based on the reaction with pure or waste calcium chloride (Solvay brine) to obtain iron(I1) chloride and gypsum as a b y product. The iron chloride solution can either...

This study was an evaluation of measuring strategies using a handheld 2D profiler for quality control of finish milled tool steel with regard to surface roughness. A selection of ball nose end mills in combination with two different tool steels (hardness 39 and 47 HRC) were used to manufacture the surfaces that were to be measured. It was found that using an appropriate measuring strategy it is...

Hot closed die forging is a regular process applied to manufacture metallic components used in supporting and fixing cable conductors in electric power transmission lines. In this forming process, the final microstructure of the workpiece depends on the control of several processing parameters. In this study, simulation of the industrial forging process of a ball hook component was performed us...

Soon after the founding of the Microsurgical Instrumentation Research Association (MICRA) in 1971, it was decided to investigate the possible use of titanium and its alloys in the production of surgical instruments suitable for use with the microscope. After an analysis of surgical instruments available at that time, it was clear to us that modifications to existing designs were required. Most ...

Planing properties of seven Australian plantation-grown eucalypts were evaluated to provide recommendations on how these species should be machined and considered for the manufacture of high quality furniture and furnishings. The surface quality produced for each species was evaluated using eight planing conditions. All species performed well producing equivalent or better results than mature t...

Laser-Gas Metal Arc (GMA) hybrid welding is fast making the transition from laboratory to production, in industries as diverse as shipbuilding to automobile manufacture. For the past 3 years, our team has striven to both develop a hybrid welding process for steel pipe, and to specify, build, and install a hybrid pipe welding system in a General Dynamics NASSCO shipyard. In March 2007, the syste...

The study examined the strength of universal joint after it was loaded with torsion. It used different materials that can withstand tensile stress in accordance accepted principles and made modifications to yoke as a result topology optimization process. determined yoke's part needed load without changing its dimensions minimize distribution. According results, maximum shear on spider original ...
