METHOD OF DETERMINING TEMPERATURE OF POLYMORPHIC TRANSFORMATION BEGINNING IN TWO-PHASE TITANIUM ALLOYS USING ACOUSTIC EMISSION

摘要

FIELD: metallurgy.;SUBSTANCE: proposed method consists in measuring activity of acoustic emission signals emitted by tested specimen in heating. Polymorphic transformation temperature is defined as temperature corresponding to the moment of stepwise decrease in aforesaid activity.;EFFECT: higher accuracy and efficiency.;2 dwg
