  • Patent number: 11941209
    Abstract: Provides in the present disclosure are a touch module, a preparation method therefor, and a display device. The touch module is formed by means of attaching a polarizing function layer to a side of a touch function layer by a first bonding layer; attaching a cyclo olefin polymer (COP) film layer to another side of the touch function layer by a second bonding layer; and attaching a third bonding layer to a side, facing away from the second bonding layer, of the COP film layer.

  • Patent number: 9650708
    Abstract: A flat steel product having a tensile strength of at least 1200 MPa and consists of steel containing (wt %) C: 0.10-0.50%, Si: 0.1-2.5%, Mn: 1.0-3.5%, Al: up to 2.5%, P: up to 0.020%, S: up to 0.003%, N: up to 0.02%, and optionally one or more of the elements “Cr, Mo, V, Ti, Nb, B and Ca” in the quantities: Cr: 0.1-0.5%, Mo: 0.1-0.3%, V: 0.01-0.1%, Ti: 0.001-0.15%, Nb: 0.02-0.05%, wherein ?(V, Ti, Nb)?0.2% for the sum of the quantities of V, Ti and Nb, B: 0.0005-0.005%, and Ca: up to 0.01% in addition to Fe and unavoidable impurities. The flat steel product has a microstructure with (in surface percent) less than 5% ferrite, less than 10% bainite, 5-70% untempered martensite, 5-30% residual austenite, and 25-80% tempered martensite, at least 99% of the iron carbide contained in the tempered martensite having a size of less than 500 nm.

  • Patent number: 8888934
    Abstract: In a method to produce formed steel parts a primary steel material is provided, which (in % by weight) comprises C: 0.02-0.6%, Mn: 0.5-2.0%, Al: 0.01-0.06%, Si: max. 0.4%, Cr: max. 1.2%, P: max. 0.035%, S: max. 0.035%, and optionally one or more of the elements of the “Ti, Cu, B, Mo, Ni, N” group, with the proviso that Ti: max. 0.05%, Cu: max. 0.01%, B: 0.0008-0.005%, Mo: max. 0.3%, Ni: max. 0.4%, N: max. 0.01%, and the remainder as iron and unavoidable impurities. The primary material is heated through at a heating temperature (TA) lying between the Ac1 and the Ac3 temperature, such that at best incomplete austenitising of the primary material takes place, is placed into a press-form tool and formed therein into the formed steel part. The formed steel part is then heated to a bainite forming temperature (TB), which is above the martensite starting temperature (MS), however below the pearlite transformation temperature of the steel.

  • Publication number: 20140007992
    Abstract: A method for generating a flat steel product comprising the steps of: melting a steel melt, comprising, in addition to Fe and unavoidable impurities (in wt %) C: 0.5-1.3%, Mn: 18-26%, Al: 5.9-11.5%, Si: <1%, Cr: <8%, Ni: <3%, Mo: <2%, N: <0.1%, B: <0.1%, Cu: <5%, Nb: <1%, Ti: <1%, V: <1%, Ca: <0.05%, Zr: <0.1%, P: <0.04%, S: <0.04%; casting the steel melt into a cast strip; heating the cast strip to an initial hot-rolling temperature of 1100-1300° C. at a heating rate of at least 20 K/s; hot rolling the cast strip into a hot strip; cooling the hot strip within 10 seconds after the hot rolling at a cooling rate of at least 100 K/s to <400° C.; and winding the cooled hot strip into a coil at a coiling temperature of up to 400° C.

  • Patent number: 8449694
    Abstract: Disclosed is a method which allows steel strip to be produced in which high hardness and good formability are combined. The following steps of operation are followed: making the steel strip from the heat-treatable steel, heating the steel strip, when coiled into the open coil, to a decarburising annealing temperature which may be up to 20° C. below the Ac1 temperature of the given heat-treatable steel and which does not exceed the Ac3 temperature of the given heat-treatable steel, annealing the steel strip, in the open coil, in a decarburising atmosphere for a decarburising annealing time of at least 90 minutes, the decarburising gas which forms the decarburising atmosphere flowing through the gaps which exist between the layers of the open coil, accelerated cooling the steel strip, the depth of decarburisation, as measured from the given surface of the steel strip, being limited to a range which is less than a quarter of the thickness of the steel strip.
