Abstract: The present disclosure relates to a composite-strengthened heat-resistant and wear-resistant aluminum alloy and a preparation method thereof, and belongs to the field of preparation of high-performance metal materials. In the composite-strengthened heat-resistant and wear-resistant aluminum alloy of the present disclosure, an Al—Si—Cu—Mg alloy is adopted as a matrix, and microalloying elements for improving the heat resistance and a heat-resistant high-entropy alloy (HEA) for improving the wear resistance are added to allow composite strengthening. The preparation method mainly includes the following steps sequentially: smelting and alloying, blowing and refining, blow-compounding, die-casting molding, solution treatment, water quenching, and cryogenic and aging composite heat treatment.

Abstract: The invention relates to a method for hardening a sheet or strip made of an aluminum alloy of the 6xxx row and to a sheet or strip produced using said method. In order to accelerate the hardening method, a multistage thermal treatment is proposed which includes a process of maintaining a second holding temperature (T2) ranging from 150 to 250° C. for a second holding time (h2) and a subsequent second accelerated cooling process, wherein the second holding process together with the subsequent second accelerated cooling process interrupts the first holding process multiple times, thereby dividing the first holding process into holding stages, in each case at a first holding temperature (TI) ranging from 60 to 140° C. and for a first holding time interval (hIa, hIb, hIc, hId, hIe) which lasts longer than the second holding time (h2).

Abstract: Provided are new high strength 6xxx aluminum alloys and methods of making aluminum sheets thereof. These aluminum sheets may be used to fabricate components which may replace steel in a variety of applications including the transportation industry. In some examples, the disclosed high strength 6xxx alloys can replace high strength steels with aluminum. In one example, steels having a yield strength below 340 MPa may be replaced with the disclosed 6xxx aluminum alloys without the need for major design modifications.
