Can you convert 2-dimensional microscopy images of hard metal surfaces that show grain structures of the polycrystalline material into 3-dimensional grain structure using machine learning algorithm to facilitate characterization of the bulk material? Can machine learning on a model be helpful on real-life data?
At Sandvik Coromant, we take many microscope pictures of metal surfaces, particularly on hard metal surfaces that show grain structures of the polycrystalline material. In its simplest form the material consists of a cobalt matrix (black) that binds WC grains (gray) together. From these 2-dimensional pictures it is desirable to characterize the 3-dimensional properties of the bulk material.The 3D grain structure information is very difficult to measure due to the material characteristics and expensive experimental methods that need to be used. A characterization experiment would need to grind down the surface in very small steps and take thousands of pictures to be able to reconstruct the 3D material.
The question is if it is possible to create a machine learning algorithm that can translate 2D pictures into the most probable “fingerprint” of a 3D material from model 3D structures?
Is there a way to prepare a thermally conducting electrically insulating polymer composite for electrical & electronic applications?
Almost all electrical and electronic equipment need to protect users from electrical shock which is why they use polymeric materials with high dielectric properties for the enclosures or housings. Almost all electrical and electronic equipment product heat during operation due to passing current; this is dissipated via conduction, convection or radiation using heat sinks, etc. A material that can combine both these properties would be a game-changer for the industry. A polymer composite with 10x the thermal conductivity of present day plastics with the same electrical insulating character can be used in several cases for direct contact with current carrying parts which maybe potential customer touch points.
Can we 3D print glass fibre reinforced plastics?
3D printing of plastics has become a household activity, with very cheap printers and raw materials for anyone to give wings to their creativity. Even in industry, 3D printing has been used to create plastic parts for assessing look & feel, prototyping, and limited performance testing. Engineering plastics have several fillers for colour, flame retardancy, strength and other properties that are not offered presently by 3D printing materials suppliers. Creating a method to 3D print short glass fibre reinforced thermoplastic or thermoset materials would open up commercial applications of engineering plastics with production volumes, similar to the production of 3D printed metal parts used in gas turbines.

How to handle accumulation of H2 in a large, closed loop nitrogen system?
When atomizing steel powder some of the hot coarser powder sticks to the chamber wall and to other powder grains. This can accumulate inside the atomization tower as a crust weighing hundreds of kg. To prevent the powder from sticking we are considering coating the powder with a thin layer of carbon by supplying some gaseous carbon containing compound into the chamber. We think a carbon coated grain will not stick to other carbon coated grains. Hot powder will react, and cold powder will not. All gaseous cheap carbon compounds seem to contain H. H will accumulate in the mainly closed loop N2 system. How to handle the H2 accumulation from a safety standpoint? (We make mainly steels with high C content and the extra C from the coating is not a problem. The carbon will diffuse during the hot isostatic pressing.)
An atomization tower is 10m in height and 3m in diameter, molten steel flows through an orifice and is turned into powder by compressed N2. 10 Tonnes of steel is atomized in each batch. N2 is normally recycled, filtered and cooled in line and is put under pressure via a big N2 compressor.

How is an image system of ground/paint/ink layer on parchment affected by RH variation on a micro-scale and macro-scale, and in relation to rate and cycling. For instance, what tensions and crack formation can be seen?
A seasonal variation is increasingly accepted for indoor environments for cultural heritage collections as a way to reduce energy consumption. The effects of changing indoor conditions on cultural heritage materials has led to stringent requirements for collection climate in the past. However, in recent years there is a tendency to relax these limits and the effects hasve been studied for several material categories, such as for instance paint on wooden panels. In the archives there are many objects with the also climate sensitive system of parchment with paint layers with a Medieval origin. There is a need to study the effects of temperature and RH changes in this material category.
What materials and/or methods could be used to provide an even, electrically conductive coating on nickel hydroxide particles?
At Saft AB in Oskarshamn, batteries with Nickel-Cadmium chemistry are manufactured with a so-called pocket-plate technology. The positive active material in NiCd batteries largely consists of nickel hydroxide particles. However, the electrical conductivity of nickel hydroxide is poor, and the material typically needs to be coated with a more conductive material in order for the battery to provide the necessary energy. The conductive coating also provides better utilization of the nickel hydroxide which is beneficial from both a financial and an environmental aspect as less nickel is needed to provide the same amount of energy. Currently, nickel hydroxide coating most often uses cobalt based compounds. With the increased demand of cobalt from the battery sector, the prices of raw material increase rapidly. Additionally, issues with sustainability are raised concerning the mining and recycling of cobalt. To enhance our product and process, we are looking for other materials to coat the nickel hydroxide. Alternatively, different methods to apply a homogeneous coated layer as efficiently as possible are also of interest.
The following are required of the coated material and method:
• High electrical conductivity
• Stable in strongly alkaline solution
• Stable in the operational potential window of the NiCd battery
• The method should be easily scaled to an industrial process
The following are desired of the coated material and method:
• Consist of earth-abundant and/or recycled raw materials
• Economically feasible to implement
