发明名称 method of determining stress of unblocking of dislocations &sgr;d at loading
摘要 A method of determining the stress of unblocking of dislocations () at loading of structurally heterogeneous low-carbon steels, using which by parallel current value of effective stresses () at loading the speed of propagation of sound vibrations (V) is measured, andis determined by change of the nature of ratio betweenand V, moreover the value of the stress of unblocking of dislocations is determined on reaching of the moment of invariability of V, at metal loading.
