Role of cementite morphology on corrosion layer formation of high-strength carbon steels in sweet and sour environments
(Peer reviewed; Journal article, 2023)The effect of cementite morphology on the corrosion layer formation of four high-strength carbon steels was studied in an aqueous solution containing CO2 and CO2/H2S. The linear polarization resistance and weight loss data ... -
Role of Information in an SME in a Local Food Supply Chain - Case Study of a Norwegian Craft Beer Retailer
(Master thesis, 2016)Demand for locally produced food is increasing and the industry is gaining increased attention. But, many challenges are present for actors in local food supply chains (LFSC), and are especially related to limited capacity. ... -
Role of Metal 3D Printing to Increase Quality and Resource-efficiency in the Construction Sector
(Journal article, 2021)Demand for the construction of new structures is increasing all over the world. Since the construction sector dominates the global carbon footprint, new construction methods are needed with reduced embodied carbon and high ... -
The Role of Sustainable Project Management in Facilities Management
(Peer reviewed; Journal article, 2023)Growth in facilities management (FM) and project management (PM) have been remarkable over the last decade. Simultaneously, the adoption of sustainability principles among organisations has also increased. The purpose of ... -
The Role of Tungsten on the Phase Transformation Kinetics and its Correlation with the Localized Corrosion Resistance of 25Cr Super Duplex Stainless Steels
(Peer reviewed; Journal article, 2020)Super Duplex Stainless Steels (SDSS) have excellent corrosion resistance due to their high concentration of alloying elements like Cr, Mo, and N. There is still, however, disagreement on the role of tungsten in the corrosion ... -
Rolling Out the Anthropogenic Aluminum Cycle: With Foci on Temporal, Geographical, and Emission Perspectives
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:95, Doctoral thesis, 2013)Anthropogenic metal cycles today confront three interconnected large challenges: an increasing global demand due to rising population and escalating industrialization and urbanization, a profound change of the global supply ... -
Room temperature creep mechanism of a Pb-Sn-Sb lead alloy
(Journal article; Peer reviewed, 2019)Lead alloys are the most common materials adopted for the production of subsea power cable sheathing. The sheathing is a layer of stable and watertight metal, which serves to prevent the electrical failure of the cable. ... -
