    Using High Pressure Coolant in the Drilling and Turning of Low Machinability Alloys (2000)

    Notes: The paper examines the results of machining tests carried out on two alloys commonly used in the aircraft industry, specifically, alphabeta type titanium alloy Ti6A14V and nickel-based superalloy of type 718. In view of their excellent mechanical properties and their resistance to a wide range of temperatures, these alloys are widely used in the manufacture of turbo-engine parts. They are extremely difficult to machine, however, for various reasons. The present aim is to consider how their drilling, turning, and milling could be made more productive.

    Notes: Abstract  The cereal cyst nematode (Heterodera avenae) is an important root parasite of common wheat. A high level of resistance was transferred to wheat from Aegilops triuncialis (TR lines) using the cross [(T. turgidum×Ae. triuncialis)×T. aestivum]. Low fertility (3–5 viable kernels per plant) was observed during the process but the surviving hybrid plants were highly vigorous. To obtain stable resistant lines further crosses to T. aestivum were performed. The resistance in TR lines seems to be transferred from the C genome of Ae. triuncialis (genomes CCUU). Ae. triuncialis was highly resistant to the two Spanish populations of H. avenae tested, as well as to four French races and two Swedish populations. The histological analysis showed a hypersensitive reaction in the roots of a resistant TR line inoculated with the Ha71 pathotype of H. avenae, whereas well-formed syncytia were observed in the roots of the susceptible control. Resistance to the H. avenae Ha71 pathotype seemed to be inherited as determined by a single dominant factor in the crosses between resistant TR lines and susceptible cultivars.
