| Popis: | There are considered the alloys of the Cr – Ni system with addition of iron, molybdenum and other alloying elements. In the alloys there varied chrome content from 35 to 55 %. The alloys were subjected to various types of heat treatment. There were measured mechanical properties at the room temperature, then the alloys were studied for the durability limit. There was additionally studied the impact of chrome content in the alloy and operation temperatures on the value of rupture stress. All the indicators studied were compared with similar parameters of the ХН77ТЮР alloy.It was established that in terms of heat resistance with the present combination of alloying elements the most optimal chrome content is 40…45 %. |
