Abstract
Guidelines for making a wise choice when selecting high temperature alloys are provided. Four groups of alloys are discussed, along with helpful selection criteria. Substantial benefits accrue from contemporary alloy manufacturing techniques. Process databases and state‐of‐the‐art forging equipment significantly impact product quality, consistency and cost effectiveness. Finally, the author suggests that the elimination of unnecessary test requirements offers potential for savings in time and money. He feels that alloy integrity can be assured by any producer who can demonstrate narrow limits of compositional control, as well as melting, remelting and hot working controls.

Abstract
Pupil autonomy, empowerment and clarity of school rules are factors underpied that the schools subscribed to different philosophies regarding pupil management. One school was largely authoritarian in its approach and the other was overly lenient. This paper emphasises the importance of furthering democratic principles of pupil participation within the context of clear rules and boundaries.
