The purpose of work at the given stage - an assessment of influence of the kinds and parameters of fields of a different nature (power, thermal, acoustic, ultrasonic and electromagnetic) on parameters of longevity of constructional materials Methods of research - methods of fractal mechanics of materials, synergetrics, mechanics of fracture, mesomechanics .It is noted, that one of the ways to increase at low temperature creep. A number of laws are revealed, allowing to plan possible ways of increase in construction materials longevity due to internal pressure relaxation and change of materials structure under the influence of acoustic and ultrasonic fields. The expediency to use multifractals in the mechanic of materials is shown at a joint action of tensile stresses and intensive magnetic fields. It is established, that strength properties of the Аmg6M alloy subjected to a complex influence of external energy fluxes are kept under a loaded condition. Experimental studies are conducted on the improvement of the properties of Аmg6M alloy properties under a complex action of tensile stresses in a zone of a deep plastic deformation, electrostimulated heating by means of high density currents, intensive electromagnetic and shock ultrasonic vibrations. The increase in the materials yield limit by factor 2 and time-to-failure under creep by factor 20,1 is achieved. The results at the given R and D factor 20,1 is achieved. The results at the given R and D kinds and parameters of the fields of different nature on the life factors of construction materials.
