摘要： A method for transferring graphene nondestructively and at a low cost. In the method, a graphene is used whose surface is coated with transferring media and whose original substrate is an electrode, the electrode is placed into an electrolyte, and the graphene is separated from the original substrate by means of the driving force of bubbles and the gas intercalation produced on the graphene electrode surface during electrolysis. Then, the graphene coated with transferring media is nondestructively combined with a target substrate. The transferring media is removed so as to transfer the graphene to the target substrate nondestructively. The transferring method results in no damage or loss with respect to the graphene and the original substrate, and the original substrate can be re-used. Furthermore, the method is easy to perform, works quickly, is easy to control, and is pollution-free.

摘要： Hot isostatic press (HIP) process for superalloy powder, to form a superalloy member. A first step HIP temperature is higher than an initial melting temperature of low-melting-point alloy powder and more than 15° C. lower than a solidus of completely homogenized alloy. Pressure is ≧90 MPa, and time is 20 minutes≦t≧1 hour. Heating is stopped after the first step to cool material until temperature is below initial melting temperature of low-melting-point phase. There is temperature keeping for ≧2 hours, to ensure low-melting-point phase, formed during cooling after first step, is completely dissolved. Alloy is cooled after second step to room temperature as furnace pressure keeping continues. Formation of an original particle boundary is prevented or there is significantly reduced the number of precipitated phases on the original particle boundary in HIP procedure, to obtain compact alloy with microscopic structures as equiaxed crystals.
