Regularities of Changes in the Microhardness of Carbon Steels during Gas Laser Cutting

The paper considers the regularities of changes in the microhardness of carbon steels during gas-laser cutting. Quantitative numerical estimates of the extent of the gas-laser thermal influence zone are made. It is shown that according to the data of durometric analysis, the length of the zone of gas-laser thermal influence reaches 2200 microns

Regularities of Cementite Decomposition in Hypereutectoid Steels

Comprehensive studies have been carried out and the main regularities of cementite decomposition during thermocyclic processing of carbon-based hypereutectoid steels have been established
