specific Embodiment approach

[0021] A specific embodiment of the present invention comprises the following steps:

[0022] A. Heat the slab to 995°C and keep it warm for 2 hours;

[0023] B. Put the slab into the forging press for forging, and the forging pressing speed is 6mm / min;

[0024] C. When the forging deformation reaches 70% of the standard value, take out the slab and reheat it to 880°C for 4 hours;

[0025] D. Put the slab back into the forging press for forging, the forging pressing speed is 3mm / min, until the forging is completed.

[0026] The thickness of the slab is 65mm, and the slab comprises the following components,

[0027] 0.02wt% C, 4.5wt% Fe, 5wt% Al, 7wt% Ti, 12wt% W, 13wt% Co, 7wt% Cr, 0.5wt% Mn, 2.5wt% Mo, and The amount is Ni.

[0028] In step A, the temperature is first raised to 750°C at a rate of 75°C / min, then kept at a temperature of 15 minutes, and then raised to the set temperature.

[0029] In step C, the initial temperature rise rate is 50°C / min, and the temperatur...

Abstract

The invention discloses a hard-to-deform superalloy slab forging process, comprising the following steps: A, heating the slab to 975-1005°C, and keeping it warm for 1-2 hours; B, putting the slab into a forging press for forging, forging The pressing speed is 5-10mm / min; C. When the forging deformation reaches 70% of the standard value, take out the slab and reheat it to 850-910°C, and keep it warm for 3-5 hours; D. Put the slab back into the forging press Forging is carried out in the machine, and the forging pressing speed is 1-3mm / min until the forging is completed. The invention can improve the deficiencies of the prior art and realize the low-temperature forging of the difficult-to-deform superalloy.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a forging process of a difficult-to-deform superalloy slab. Background technique [0002] Difficult-to-deform superalloys have high cross-form resistance, many high-temperature strengthening phases, and poor plasticity. It is difficult to achieve effective processing by ordinary processing and forging processes. And hard-to-deform superalloys are necessary materials in many special industries, so how to optimize the processing and forging methods of hard-to-deform superalloys has become one of the hot spots in this field of research. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hard-to-deform superalloy slab forging process, which can solve the deficiencies of the prior art and realize low-temperature forging of the hard-to-deform high-temperature alloy. [0004] In order to solve the above technical problems...
