    • PURPOSE: A high-sensitive magnesium alloy sheet and a manufacturing method thereof are provided to improve normal temperature strength and hardness by controlling formation of intermetallic compounds and grain refinement. CONSTITUTION: A manufacturing method of a high-sensitive magnesium alloy sheet comprises the following steps of: manufacturing molten metal by dissolving alloy; maintaining the temperature of the molten metal; manufacturing a magnesium alloy sheet by injecting the molten metal between to cooling rolls(30); processing the magnesium alloy sheet at a temperature of 250 ~ 450°C for 1 ~ 24 hours; pre-heating the magnesium alloy sheet at the temperature of 150 ~ 450°C; rolling the magnesium alloy sheet; and processing the magnesium alloy sheet at the temperature of 150 ~ 400°C for 0.5 ~ 10 hours.
    • 目的:通过控制金属间化合物的形成和晶粒细化,提供高灵敏度镁合金板及其制造方法,以提高常温强度和硬度。 构成:高灵敏度镁合金板的制造方法包括以下步骤:通过溶解合金来制造熔融金属; 保持熔融金属的温度; 通过将熔融金属注入到冷却辊(30)之间来制造镁合金板; 在250〜450℃的温度下加工镁合金板1〜24小时; 在150〜450℃的温度下预热镁合金板; 轧制镁合金板; 并在150〜400℃的温度下加工镁合金板0.5〜10小时。
