    2020

    Thermal conductivity is a crucial quality of metals since it measures the amount and speed of heat the material can displace. This quality is especially important in high-temperature environments. Extremely high temperatures can change the properties of any metal, usually reducing the strength. Therefore, conducting the heat quicker can significantly reduce the stress on the […]

    2020

    Conventional steelmaking using electric-arc furnaces and decarburization is still very common. However, the internal structure of the cast ingots made with this process isn’t uniform, which negatively affects the qualities of the steel. Sure, a hot method can be used on the ingots to break up the segregated structure, but the structure still won’t be […]

    Applying heat to metals can make them easier to forge, machine, weld, and fabricate. However, this also brings some issues with it, metals expand when heated, which makes the whole fabrication process more demanding. Luckily, every alloy comes with a predetermined coefficient of thermal expansion. This coefficient shows how much a given alloy will expand […]
