摘要：
A method and apparatus for direct writing of single crystal super alloys and metals. The method including heating a substrate to a predetermined temperature below its melting point; using a laser to form a melt pool on a surface of the substrate, wherein the substrate is positioned on a base plate, and wherein the laser and the base plate are movable relative to each other, the laser being used for direct metal deposition; introducing a superalloy powder to the melt pool; and controlling the temperature of the melt pool to maintain a predetermined thermal gradient on a solid and liquid interface of the melt pool so as to form a single crystal deposit on the substrate. The apparatus configured to generally achieve the aforementioned method.
摘要（中）：
用于直接写入单晶超级合金和金属的方法和装置。 该方法包括将基底加热至低于其熔点的预定温度; 使用激光在所述基板的表面上形成熔池，其中所述基板位于基板上，并且其中所述激光器和所述基板可相对于彼此移动，所述激光用于直接金属沉积; 在熔池中引入超合金粉末; 并且控制熔池的温度以在熔池的固体和液体界面上保持预定的热梯度，以便在衬底上形成单晶沉积物。 该装置被配置为一般地实现上述方法。
