Definition of hot-short in English:



  • (of a metal) brittle when hot.

    • ‘Hot-short compositions are weak at elevated temperatures.’
    • ‘Thus, the higher silicon alloys normally are used for more complex castings and for permanent mold and die casting processes, which cannot tolerate hot-short alloys.’
    • ‘We have discovered that the hot-short problem can be overcome through a combination of alloying and thermomechanical processing steps.’


Late 18th century: from hot + short suggested by the earlier red-short, from Swedish rōdskōr (from rōd ‘red’ + skōr ‘brittle’).
