description: For the study, we selected rods of alloy D1 with a diameter of 60 mm and alloy AK4-1 with a diameter of 40 mm as supplied, as well as stamped blanks from alloys D1 (suspension and impeller) and AK4-1 (piston) before heat treatment. This work is devoted to the study of the influence of various factors on the electrical conductivity of heat-treated aluminum alloys and the study of the possibility of replacing 100% quality control of heat treatment of parts made of wrought aluminum alloys by measuring the Brinell hardness by measuring the electrical conductivity by the eddy current method. To achieve the set goals, it is necessary to solve the following tasks: - to determine the relationship between the quality of hot-rolled alloys D1 and AK4-1 with the readings of devices - electrical conductivity meters - structureroscopes; - set the boundary values of electrical conductivity at which the heat-treated alloy meets the technical specifications of the drawing in terms of hardness. The work was carried out on the basis of OAO "Red October", where a significant part of the factual material was collected: the results of metallographic analysis, physical and mechanical properties, electrical conductivity of prototypes. All samples were subjected to heat treatment in various modes. After heat treatment, the hardness of the samples was measured on a Brinell device with a 010 mm ball, at a load of 1000 kg. Mechanical properties were determined by tensile tests on a R-5 tensile testing machine. Samples before and after heat treatment were examined using a Constant K6 device for electrical conductivity. The microstructure of the heat-treated samples was studied on an Axiovert optical microscope at a magnification of 200 and on a LEICAVHMTAUTO microhardness tester at a magnification of 500. Also, in laboratory conditions, a study was carried out of the influence of the following factors on the electrical conductivity of alloys D1 and AK4-1: - temperatures of hardening to artificial and natural aging; - temperature of artificial aging; - duration of natural and artificial aging; - cooling rate during quenching; - fiber directions; - chemical composition. As a result, the influence of the heat treatment mode of D1 and AK4-1 alloys on the mechanical properties and electrical conductivity was investigated, the effect of hardening and aging temperatures on the electrical conductivity of D1 and AK4-1 alloys was studied, a method of non-destructive quality control of heat treatment of parts made of D1 and AK4-1 alloys was developed. with the help of a meter of electrical conductivity "Constant K-6" and established technically justified control standards for electrical conductivity for each alloy.
