Studying the effect of boron on heat-resistance properties of Ni-Cr alloys

[摘要] Heat-resistant alloys based on Ni-Cr system are widely used as alloys for the manufacture of rings, fasteners, turbine disks and other parts operating at temperatures up to 750 °C. To improve the properties of these alloys, these are additionally doped by Al, Ti, Mo and other elements.
