  1. 6. Effects of Austempering Process on Mechanical Behavior Properties of Compacted Graphite Iron

    University essay from Högskolan i Jönköping/JTH, Material och tillverkning; Högskolan i Jönköping/JTH, Industriell produktutveckling, produktion och design

    Author : INAMUL HASSAN; [2019]
    Keywords : AusCGI;

    Abstract : The thesis paper here focuses on the effects of the austempering temperature (TA) and the austempering time (tA) on the unalloyed fully ferrite Compacted Graphite Iron (CGI), to obtain improve in mechanical properties and the study of the microstructure. The unalloyed CGI samples were austenitised at 850oC for 60 and 90 min and were then heat treated at 275, 325 and 375oC with different holding times at 30,60,90, and 120 mins. READ MORE

  3. 7. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method

    University essay from KTH/Energiteknik

    Author : Aravind Ganesan; [2019]
    Keywords : syngas; Cobalt; Fischer-Tropsch; alcohols; hydrocarbons; syngas; kobolt; Fischer-Tropsch; alkoholer; kolväten;

    Abstract : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. READ MORE

  4. 8. Characterization of black corrosion in reinforced concrete structures: analyses of field samples from southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Jenny Halling; [2019]
    Keywords : black rust; anaerobic corrosion; reinforced concrete; corrosion products; green rust; microbial corrosion; Earth and Environmental Sciences;

    Abstract : I den här studien karakteriseras fenomenet anaerob korrosion utifrån både litteraturstudier om korrosionsprocesser och korrosionsprodukter samt genom undersökning av fältprover från betongkonstruktioner i salthaltiga undervattensmiljöer i södra Sverige. Anaerob korrosion av armering i vattenmättad betong är ett omfattande men hittills relativt ouppmärksammat problem. READ MORE

    Abstract : This thesis aims to provide adequate analytical information on the spade shaped iron bars of Norrland and central Sweden. While their significance has been thoroughly debated for decades, analytical research on them has been confined to cases of single artefacts or theoretical interpretations of their value, meaning and origin.
