1results about How to "Solve thermal conductivity" patented technology

This invention belongs to the field of thermal storage materials technology and discloses a high thermal conductivity, low expansion magnesium-based thermal storage alloy, which is composed of the following components by weight percentage: 81.2% WE43 rare earth magnesium alloy, 8% Ti2AlC powder, 6% manganese powder, 4% aluminum powder, and 0.8% boron powder. Using WE43 rare earth magnesium alloy as a stable matrix, and combining Ti2AlC powder with manganese, aluminum, and boron powder, an optimal ratio system of matrix, high thermal conductivity phase, and gradient phase precursor is constructed. This achieves synergy between the thermal conductivity of Ti2AlC and the low expansion of the Mn-Al-B gradient phase, fundamentally solving the problem of the mutual constraint between thermal conductivity and low expansion performance in traditional magnesium-based alloys. The Ti element acts as a bridge to strengthen the bond between the bifunctional phase and the magnesium matrix, preventing functional phase detachment and aggregation. Ti2AlC forms a continuous thermal conductivity path to improve heat transfer efficiency, while the Mn-Al-B gradient phase precisely controls the coefficient of thermal expansion, enabling the alloy to maintain high thermal conductivity, low expansion, and low decay rate over a wide temperature range. Furthermore, its high density and excellent surface quality enhance its structural stability and recyclability.
