ИССЛЕДОВАНИЕ ВЛИЯНИЯ ГАФНИЯ НА СТРУКТУРУ И СВОЙСТВА ЛИТЕЙНОГО ЖАРОПРОЧНОГО КОРРОЗИОННОСТОЙКОГО НИКЕЛЕВОГО СПЛАВА

It has been investigated the influence of hafnium within the alloying range from 0,1% to 0,9% by mass on structure and mechanical properties of alloy AEN3EN. The results of mechanical testing and metallographic investigation of experimental chemical compositions with variable hafnium content inside the alloying range in comparison with alloy AEN3EN free of hafnium have been represented.
