METHOD OF PARTS MANUFACTURING BY SINTERING OF Co-Cr-Mo ALLOYS HAVING IMPROVED PLASTICITY AT HIGH TEMPERATURES Russian patent published in 2015 - IPC B22F3/12 B22F3/24 C22C19/07 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, in particular to methods of parts manufacturing by additive sintering. Method of part manufacturing is suggested based on Co-Cr-Mo alloys having average ultimate elongation at 800°C and higher over 10% and average yield strength at 800°C over 400 MPa. Method includes the sintered part manufacturing by the additive sintering of the alloy powders based on Co-Cr-Mo, two heat treatments with intermediate cooling.

EFFECT: brittleness of the manufactured parts is reduced, plasticity and yield strength at high temperatures increase.
