i' i rs t s ;eps have been takerk in the appl i cat ion o f the theor;/
to the analysis of structural changes and phase transformations.
Further applications would appear tp hold considerable promise
in the development of basically new methods of increasing the
;strength t>f' metals. In the light of these considerations, the
author believes it probable that the theory may be used for ms,kin~;
broad generalizations about the nature of diverse processes
occurring in metals, as well as for developing new methods ~f
controlling these processes afi a means of producing new propertieso
Pao personalities are mentioned. There are 49 references: 13

analysis of 134 curves of lasting resistance (which were
collected from the literature) confirm the correctz~asti of
the sugrasted axpressiaris. The dependence of the .lasting
resistance for durations of use (srak slu~hby) up to 144 404

Recommendations are made concerning the margin of strength
when the plastic properties of material are taken into con-
sideration for those machine parts which work under high
temperatu~^es. Anew equation is suggested for the extra-
polation of the relation "stress-time" when testing for a
ton -lasting strength. Diagrams. References: 3 Russian,
