  1. 1. Effects of natural aging and low strain-rate on mechanical properties of aluminium alloy sheets used in automotive industry

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Amirhossein Gholami; Ali Abedisamarin; [2024]
    Keywords : Ageing. AA6014. AA6016;

    Abstract : These days, lightweight materials such as aluminum alloy sheets, especiallythose in the AA6xxx series, are in high demand for use inthe automotive industry. During natural aging, the properties of aluminummay undergo significant changes due to the diffusion of atomswithin the crystal structure, impacting the strength and formabilityof aluminum sheets.

  4. 3. Brownification in a small stream originating from a peatland - A case study from Ryds Å in south Sweden

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Emelie Ström; Frida Karlsson Öhman; [2024]
    Keywords : Brownification; Peatland; Bolmen; DOM; Water Quality; Inflow; Technology and Engineering;

    Abstract : Brunifiering syftar till en process där vattnet blir brunare på grund av ökade halter av naturligt organiskt material och järn, vilket innebär utmaningar för miljön och människor. Sjön Bolmen i södra Sverige har problem med brunare vatten. READ MORE

  5. 4. High-Temperature Thermal Energy Storage for Innovative Hybrid CSP/PV Plants : A Comprehensive Design Optimization

    University essay from KTH/Energiteknik

    Author : Lorenzo Centonze; [2023]
    Keywords : ;

    Abstract : By means of a literature review, critical parameters in the context of thermal energy storage systems, particularly packed bed thermal energy storage systems are identified. The goals of this thesis project are to come up with an optimized design for a PBSTES and to evaluate the thermal performance of alternative storage materials derived from byproducts of industrial processes and natural rocks in order to reduce the environmental impact of the designed system.
