Abstract: A method for preparing Mg-RE alloys with high strength and ductility using selective laser melting (SLM) additive manufacturing technology includes the following steps of: A. preparing Mg-RE-(Zn)—Zr pre-alloyed spherical powder by gas atomization; B. molding the Mg-RE-(Zn)—Zr pre-alloyed spherical powder using SLM to obtain the Mg-RE alloys with high strength and ductility; and C. conducting heat treatment on the Mg-RE alloys prepared in step B: solid solution+aging treatment or only aging treatment The method adjusts and controls microstructure and mechanical properties of the alloys by adjusting and controlling process parameters of SLM (laser power, scanning speed, hatch spacing, spot diameter, layer thickness, interlayer rotation angle, substrate preheating temperature, partition width and overlapping area width) and process parameters of subsequent heat treatment (temperature and time) to prepare the Mg-RE-(Zn)—Zr alloys with high strength and ductility using SLM process for the first time.

Abstract: Embodiments of the present disclosure provide a data processing method, a controller, a storage device, and a storage system. The controller adds an execution time of an IO request to the IO request, and the execution time is used to instruct the storage device to complete the IO request before the execution time expires. The controller sends, to the storage device, the IO request to which the execution time is added. When receiving the IO request, the storage device can execute the IO request based on the execution time of the IO request.

Abstract: A storage array includes a plurality of hard disks, where each of the hard disks is divided into a plurality of chunks, and a plurality of chunks of different hard disks form a chunk group using a redundancy algorithm. The storage array obtains fault information of a faulty area in a first hard disk, and determines a faulty chunk storing the lost data according to the fault information. The storage array recovers the data in the faulty chunk using another chunk in a chunk group to which the faulty chunk belongs and stores the recovered data in a recovered chunk. The recovered chunk is located in a second hard disk which is not a hard disk for forming the chunk group.
