Abstract

See full text

A method utilizing cold welding to prepare grain boundaries having different included angles includes using a device including a support member. Two bent members are arranged opposite to each other in the support member. One ends of the two bent members are both fixedly connected to the support member, one end, away from the support member, of any bent member is fixedly connected to a first sample, one end, away from the support member, of the other bent member is fixedly connected to a second sample, and the first sample and the second sample are arranged corresponding to each other. The bent member includes a first metal sheet and a second metal sheet having different thermal expansion coefficients. An angle between the first sample and the second sample during butt welding can be controlled by changing an included angle of a bimetallic sheet.
