Description
Technical field
The present invention relates to materials hot working extrusion technique field and material experiment research field, be full-automatic Equal Channel Angular Pressing equipment installation method, belong to mechanical field.
Technical background
Titanium alloy has the advantages such as specific strength is high, decay resistance is strong, since the 50's of 20th century come out, be widely used in the various fields such as space flight and aviation, military affairs, ocean, boats and ships, biomedicine, chemical industry and the energy, become the novel key structure material with powerful vitality, there is very important using value and wide application prospect; Nearly β type Ti-5553 alloy is a kind of novel high-strength high-fracture toughness titanium alloy developed by Russian alloy B T22F; With Ti-1023 alloy phase ratio, this alloy can not produce obvious component segregation, there is excellent strength and fracture strength advantages of higher, have good quenching degree and wider processing technology scope, be particularly suitable for manufacturing the parts that must bear huge stress, than being more suitable for jockey etc. between structural member and undercarriage, wing, engine hanger, day by day favored in aerospace industry.
The quality of Ti5553 alloy own is softer, Erosive Properties is poor, difficulty is processed, obdurability coupling can not meet aviation requirement well, limits the further application of high-strength Ti5553 alloy to a certain extent.According to relevant statistics: in the parts such as space flight and aviation engine, advanced engine compressor blade all adopts titanium alloy, in use, high velocity air drives dust and the grains of sand etc. in air to cause serious erosion to front grade blade, and its life-span can be reduced to 1/10 of ordinary life; In marine machinery, screw, valve and pipeline etc. use titanium alloy in a large number, and the erosive wear of material can cause the decline of the premature abrasion of the flow passage components such as the hydraulic turbine, water pump, efficiency and the lost of life etc., causes huge loss to national economy.
Equal channel angular pressing platen press (ECAE) is a kind of forced plasticity deforming method obtaining ultra-fine grain, is proposed the earliest and obtain the attention of many researchers by Segal.ECAE key is that pure shear is out of shape, the reciprocation of shearing deformation causes grain refinement, the Microstructure evolution being extruded material controls by the work hardening in extrusion process, dynamic recovery and dynamic recrystallization, finally reaches crystal grain thinning, improves the object of material comprehensive mechanical property.
ECAE die channel corner, extruding passage, extruding route, extrusion temperature, extrusion speed and friction etc. all directly can affect the combination property of the Ti5553 alloy be extruded, therefore, a set of suitable equal channel angular pressing compression experiment device, it is very necessary for studying for the ECAE carrying out Ti5553 alloy.But existing domestic and international ECAE experimental provision or mould exist following shortcoming: rigidity and the anti-unstability ability of (1) push rod are undesirable, easily cause extruding unsuccessful; (2) sample and push rod loading mould can expend the regular hour, and especially sample filling cumbersome can cause specimen temperature decline severe; (3) the sample demoulding is more difficult, and need dismounting experimental provision or mould, or by knocking sample, could take out sample, easily cause sample deformation, inconvenient experimental study, causes adverse influence to experimental result; (4) automaticity is low, needs manual operation to control, and has certain requirement to the technical merit of experimenter, the failure of an experiment because misoperation causes may occur, and mounting means is also very exquisite, once setup error will directly be scrapped.
In summary, existing ECAE experimental provision or mould can not meet the experimental study to Ti5553 alloy extrusion efficiently, and existing equipment installation method is very crucial, and it is directly connected to the quality of final finished.
Summary of the invention
The object of the invention is to the deficiency overcoming existing ECAE experimental provision and installation method, provide a kind of full-automatic device of applicable experimental occasions.
