FIELD: metallurgy.
SUBSTANCE: tested resilient element is strained several times to maximum deformation with registration of acoustic emission signals at every straining. Note here that tested element is strained two times and for short term by reduction while acoustic emission signals are registered continuously during second straining to define total quantity of pulses of total acoustic emission N2. Resilient element titanium alloy microstructure is evaluated by nine-point scale of grain size divided into three sets of point 4-5, 6-7 and 7-8 each corresponding to s separate range of the number of pulses of total acoustic emission A1, A2, A3. Microstructure quality are defined by pints of said scale from the following relationship: N2≤A1, or N2≤A2, or N2≤A3.
EFFECT: fast and simplified process for control over plate spring heat treatment conditions.
