  • Imaging and analysis of chip formation during orthogonal cutting of titanium alloy

    Orthogonal cutting of titanium alloy Ti-6Al-4V was investigated in a series of continuous and interrupted turning tests. Direct observation of the chip formation zone was achieved using a high speed imaging system with a long-distance microscope lens. Frame rates from 20,000 to 50,000 frames per second were used to record the chip formation cycle over a range cutting speeds from 4 to 150 m/min ...

  • Fatigue initiated overload failure of a 4130 alloy steel pump shaft

    This paper describes the failure investigation of a vertically mounted tank cleaning pump system from an off–shore oil platform. The incident involved the catastrophic failure of an intermediate shaft, connecting pump shaft and surrounding components. Corrosion to the shaft ball bearings on the pump shaft generated excessive vibrations which transferred via a universal joint to the connecting ...

  • Analysis of precious metals in jewelry

    Abstract For thousands of years, man learned the craft of making jewelry from gold. Gold is a noble metal which does not react with the air and has a shiny yellow color.Over the years, alloying of the gold was necessary to improve its properties since pure gold is too soft to be used for jewelry. Alloying of the gold is usually by low-cost metals such as copper, zinc, silver or nickel. ...

  • Sample preparation is the key to quality analysis with a laser analyser

    Sample preparation is the most important step of any chemical analysis. To get the best results with any elemental alloy analyser regardless of the technology, the sample must be clean before taking a measurement. Otherwise the results are always compromised at least to some extent. The effect of dirty surfaces will vary and some technologies are more forgiving to sample surface conditions than ...

  • Gas cell selection for analysis of electronic gases

    APIMS and FTIR remain the preferred analytical tools for monitoring impurities in the electronic  specialty gases used by the semiconductor industry, although other tools such as CRDS are currently finding application in selected cases. FTIR spectroscopy offers the advantage of the simultaneous measurement of all gaseous species that exhibit dipole moment changes during vibrations at ...

  • Analysis on significance of the factors influencing shearer drum cutting performance

    In order to get the significant factors which affect shearer drum's cutting performance, orthogonal test was conducted in the coal cutting bed with model drums and model picks. After that, the work of significance analysis was carried out based on the test results. The analysis indicates that: in orthogonal test of drums, coal compressive strength and cutting depth have obvious effects on cutting ...

  • Structure and magnetic properties of nano-sized HoFe2O4 material

    A mixture of Ho2O3 and Fe2O3 were mechanically alloyed followed by subsequent annealing to produce a single nanocrystalline HoFe2O4 phase. XRD patterns and magnetisation hysteresis curves were obtained for both the as-milled and annealed samples. XRD analysis indicates the formation of an initial amorphous phase in the as-milled powder. After annealing up to 1200°C, the material crystallises ...

  • Air crash investigation using Oxford Instruments handheld analysers - case study

    It was late April 1945 during the last days of World War II for Italy. Just one week before the liberation of Italy from the fascists rule, a group of five Messerschmitt BF 109 planes took off from the Vicenza airbase heading to Ghedi, near Brescia. This was not a combat mission but a transfer flight. Soon after take-off the planes were intercepted by US fighters and attacked. All five planes ...
