摘要：
The effect of heat treatment on the mechanical properties and microstructure of refractory nickel alloy GH3536 obtained by selective laser melting is determined. Growth in the quenching temperature is accompanied by lowering of the ultimate strength and of the yield limit under static tension, while the elongation increases. After 1-h quenching from 1100°C and 10-h aging at 700°C the fracture behavior of the alloy changes from brittle one to ductile one, the strength and the hardness decrease, and the ductility grows by about a factor of 3.5 as compared to the initial condition.
