Definitions
- the alloys have a high creep resistance, a high ductility and a high tensile strength.
- the invention relates to a zinc-titanium wrought alloy and a method of working it.
- a wrought zinc alloy for sheets, strips, tubes, rods and wire in addition to the requirement of adequate strength properties must also be suited for perfect cold working by folding, bending, pressure application and drawing. These properties are obtained in many of the wrought zinc alloys employed in industry.
- titanium-containing wrought zinc alloys with 0.05 to 0.5% titanium and 0.05 to 1.50% copper have a good creep resistance which reaches its maximum by hot working at temperatures of 150 to 300C or cold working with subsequent hot working at temperatures between 150 and 300C.
- the tensile strength in these cases increases with increasing copper contents from about 11 kp/mm to 28 kp/mm while at the same time the creep resistance increases from 6 kp/mm to 9 kp/mm and the residual elongation is limited to 1 percent per year.
- the increase of the creep resistance is principally obtained by a superfine grain due to the titanium contents.
- the increase in strength of the zinc alloy is undesirably associated with a strong increase of the elasticity.
- the resultant rebound therefore is an obstacle for a permanent set or deformation of the sheets or strips which are for instance shaped by machines to channel-formed members or tubes.
- the cold brittleness of these zinc alloys increases fairly substantially.
- the formed sheets and strips therefore have a small ductility as can be determined by means of the folding test. For instance sheets and strips show' indications of fracture at a direct folding by 180 at room temperature and below. A break-free folding by 180 is possible only if the wrought alloy is hot worked or cold worked with a subsequent heat treatment.
- the manganese content is between 0.04 and 1.20 percent.
- the invention also involves a process for improving the properties of the alloy by subjecting it to hot rolling at 120 to 350C to the desired final dimensions or cold rolling to the final dimensions at temperatures between 20 and 120C followed by aging for at least one hour at 120 to 350C.
- the alloy of the invention there should not be present, as impurities, more than 0.15 percent total content of copper and in no case more than up to 25 percent of the contents of manganese. Likewise the iron should not be in excess of 10 percent of the manganese contents and the maximum should be 0.03 percent.
- the alloys described in these examples were obtained by mixing in molten condition and were then cast at 450C to ingots of a thickness of 80 mm each. After solidification the ingots were cooled rolled in order to form sheets and strips of a thickness of 1 mm. The cold rolling was effected in several passes. Subsequent the elongation, tensile strength, creep resistance and foldability were determined to obtain a picture of the properties of the alloy.
- the properties of the alloy were as follows:
- the properties of the alloy were as follows:
- the properties of the alloy were as follows:
- the accomplishments of the alloys of the invention are particularly in the features of a high ductility and high tear resistance along with a high creep resistance.
