Technological Support for the Cultural Training System for Students at Technical Universities

The paper studies the trends of higher technical education development and establishes the relationship between education and culture as one of the conditions for solving the problems of modern society. The authors determine that one of the main problems that hinder the formation of the culture of the future engineer is the lack of a reasonable selection of cultural elements. The presence of such elements ensures the full development of the specialist. The most generalized socio-cultural components of culture are (1) the sphere of material production, (2) the cultural sphere, and (3) the sphere of communication. The authors determine the components of the culturological training content as the implementation of the support system of the integrated professional, universal cultural, and moral cultural development of technical university students. It is experimentally proved that the implementation of a cultural training system of a future engineer leads to statistically significant changes in the levels of knowledge acquisition, the formation of skills and qualities of a future specialist

KINETICS OF PHASE TRANSFORMATIONS IN HIGH-CARBON ALLOYS OF THE Fe–Cr–C SYSTEM

A model is presented of phase transformations (dissolution of M7C3 carbides in austenite on heating, carbide precipitation on cooling, pearlite and martensite transformations) in the Fe–Cr–C alloys. It permits to predict the results of heat treatment or to select the chemical composition of an alloy for prescribed requirements.Представлена модель основных фазовых превращений (растворение карбидов M7C3 в аустените при нагреве, выделение вторичных карбидов при охлаждении, перлитного и мартенситного превращений аустенита) в сплавах типа штамповых сталей или износостойких чугунов, относящихся к системе Fe–Cr–C. Модель позволяет предсказывать результаты термической обработки или подбирать химический состав сплава по заданным требованиям

HARDNESS CALCULATION FOR QUENCHED HIGH-CHROMIUM IRON-CARBON ALLOYS

A model is presented able to calculate the Rockwell hardness of high.chromium steels and wear.resistant cast irons belonging to the ternary system Fe–Cr–C after quench hardening. The model is based on thermodynamic and kinetic calculations and numerical estimation of microhardness of individual structural components of the alloy.Представлена модель расчета твердости по Роквеллу высокохромистых сталей и износостойких чугунов тройной системы Fe–Cr–C после закалки, основанная на термодинамических и кинетических расчетах и расчетной оценке микротвердости отдельных структурных составляющих сплава
