Plate internal stress and processing hardening need to be made annealing treatment, TA1 is heated to it is air-cooled after 780 DEG C of heat preservation 2h, by 6061 aluminium of AA
Alloy is heated to air-cooled after 350 DEG C of heat preservation 2h.
The face to be composite of titanium plate and aluminium sheet after annealing is surface-treated, the greasy dirt impurity and oxygen of plate surface are removed
Compound, the combination of dissimilar metal when being conducive to rolling.This experiment first with sander removal metal surface to be composite impurity and
Oxide, then clean surface repeatedly with acetone and alcohol and dried up with blowing hot wind.The aluminium sheet group with room temperature is needed after titanium plate heating
It is sent into mill milling simultaneously after conjunction, but since titanium plate is relatively thin, operating delay can cause significantly temperature drop within several seconds, influences experiment knot
The objectivity of fruit.So one piece of iron plate is first heated to titanium plate rolling required temperature, then titanium plate is put into furnace in Rolling compund
In iron plate on keep the temperature 5 minutes, iron plate and titanium plate are taken out together then and are put at inlet of rolling mill, iron plate plays titanium plate at this time
The effect of heat preservation, then titanium/aluminium is obtained compound at once by the aluminium sheet of the titanium plate of heating and room temperature push-in milling train with guide and guard push plate
Plate.
