Sažetak
This paper presents the influence of the weapon barrel superheat on the change of its material structure and hardness. The barrel material directly exposed to the firing process which has a very strong and dynamic thermal, mechanical and chemical effect on the barrel. In this way the firing process causes a strong wear of the barrel. The test samples have been made of the barrel material taken from the 76 mm field gun. The test samples were tempered at 600, 700, 800 and 900 celsius, over a period of the one hour and air cooled. It's the similar way of heating and cooling as the superheat and cooling of the barrel by intensive firing. The test has shown that determined rate of fire must not be exceeded by the weapon firing, because the barrel superheat changes significantly the microstructure and mechanical quality of the weapon barrel material. These changes cause the wear resistance decrease of weapon barrel material.
