Abstract
Disclosed is a method for producing a composite material, wherein two or more composite components are arranged with respect to one another by casting to form a composite, so as to create a contact region essentially without a material bond between the composite components, wherein the composite components are thereafter materially bonded to one another in the contact region by means of a hot-rolling process.
Claims19
A method for producing a composite material, the method comprising:
- providing a solid first composite component, wherein the first composite component is made from one of:
- a carbon steel;
- a rust-, acid-, and heat-resistant steel;
- an FeAlCr steel;
- an FeMn steel;
- a Ni-alloy;
- and
- a Ti-alloy;
- casting a second composite component in contact with the first composite component to create a third composite component, wherein for the third composite component, a contact region is formed between the first composite component and the second composite component in which there is no material bond between the first composite component and the second composite component in the contact region, wherein:
- said casting step comprises creating a temperature difference of at least 500° C. between the first composite component and the second composite component in air,
- the temperature difference causing the second composite component to contract against the first composite component to minimize air inclusions;
- and
- materially bonding the first composite component to the second composite component in the contact region by hot-rolling the third composite component.
A method for producing a composite material, the method comprising:
- providing a solid first composite component;
- casting a second composite component around the first composite component,
- wherein a contraction of the second composite component takes place during the casting causing the second composite component to mechanically join with the first composite component in a form-fitting manner such that the first composite component is enclosed by the second component and air inclusions are minimized, a contact region is formed between the first composite component and the second composite component, the contact region being devoid of a material bond between the first composite component and the second composite component, and
- the casting step comprises creating a temperature difference of at least 500° C. between the first composite component and the second composite component in air;
- and
- subsequently materially bonding the first composite component to the second composite component in the contact region by hot-rolling to form a third composite component.
A method for producing a composite material, the method comprising:
- providing a solid first composite component, wherein the first composite component is made from one of a carbon steel, a rust-, acid- and heat-resistant steel, an FeAlCr steel, an FEMn steel, a Ni- or Ti-alloy;
- casting a second composite component in contact with the first composite component to form a third composite component, wherein:
- the casting step includes creating a temperature difference of at least 500° C. between the first composite component and the second composite component in air;
- and
- a contact region is formed between the first composite component and the second composite component in which there is no material bond between the first composite component and the second composite component in the contact region;
- during the casting of the second composite component, contracting of the second composite component to mechanically join the second composite component with the first composite component in a form-fitting manner to minimize air inclusions;
- and
- subsequently materially bonding the first composite component to the second composite component in the contact region by hot-rolling the third composite component.
