DEVELOPMENT OF THE PRODUCTION OF LIGHT ALLOYS,
Abstract
The development and the present status of the production of aluminum, magnesium and titanium alloys are reviewed, and current problems in the production technology of these alloys are outlined. One of the important problems in improving the quality of semifinished products from aluminum alloys is to improve the homogeneity of their structure and to eliminate local discontinuities in metal. The problem is being solved by decreasing the content of oxide inclusions and hydrogen and by increasing the metal density by using hydrostatic compression in the first stage of deformation. One of the most promising methods of strengthening aluminum alloys is structural strengthening which consists essentially in producing a nonrecrystallized (polygonized) structure in alloys after heat treatment. The problem of increasing the heat resistance of aluminum alloys is being solved mainly by developing SAP-base alloys, alloys with refractory metals, and aluminum alloy-base composites. (Author)
