  • Patent number: 11506238
    Abstract: A thermally stabilized fastener system and method is disclosed. The disclosed system/method integrates a fastener (FAS) incorporating a faster retention head (FRH), fastener retention body (FRB), and fastener retention tip (FRT) to couple a mechanical member stack (MMS) in a thermally stabilized fashion using a fastener retention receiver (FRR). The MMS includes a temperature compensating member (TCM), a first retention member (FRM), and an optional second retention member (SRM). The TCM is constructed using a tailored thermal expansion coefficient (TTC) that permits the TCM to compensate for the thermal expansion characteristics of the FAS, FRM, and SRM such that the force applied by the FRH and FRR portions of the FAS to the MMS is tailored to a specific temperature force profile (TFP) over changes in MMS/FAS temperature. The TCM may be selected with a TTC to achieve a uniform TFP over changes in MMS/FAS temperature.

  • Patent number: 11459648
    Abstract: Provided is a performance controlling method for a high-strength aluminum alloy shell during an ultra-low temperature forming process. The present disclosure greatly improves the performance of an aluminum alloy sheet by applying an ultra-low temperature. The present disclosure cools the aluminum alloy sheet to an ultra-low temperature by using an ultra-low temperature cooling medium, so as to compensate for insufficient hardening caused by insufficient deformation and avoid cracking caused by increased deformation. The present disclosure cools the sheet blank zonally according to a deformation law of a desired curved part, and controls the ultra-low temperature distribution of the sheet blank during forming so as to promote the formation of a substructure in a small-deformation zone. In this way, the present disclosure improves a subsequent age-hardening effect, and corresponding uniformity of microstructure and performance, and effectively solves the problem of non-uniformity due to uneven deformation.
