摘要： Provided is a rare earth magnet that allows suppressing deterioration of magnetic properties and a method for manufacturing the same. The rare earth magnet of the present disclosure includes a magnet body containing a rare earth element R1, a transition metal element T, and boron B and includes a main phase. A region in the vicinity of a corner portion of the magnet body of a constituent surface constituting a surface of the magnet body is a processed surface on which a removal process has been performed, and a region closer to a center than the region in the vicinity of the corner portion of the constituent surface is a non-processed surface on which the removal process is not performed.

摘要： According to the present invention, a process for producing an aluminum alloy material, whereby reduction in toughness and in fatigue strength of the aluminum alloy material can be inhibited even after solution treatment is provided. Also, the following is provided: a process for producing an aluminum alloy material comprising at least the steps of subjecting a heat treatable aluminum alloy material to solution treatment and applying aging treatment to the aluminum alloy material subjected to solution treatment, which further comprises the following step between the solution treatment step and the aging treatment step: the step of subjecting the aluminum alloy material to plastic forming in a manner such that a given amount of equivalent strain is imparted to the aluminum alloy material from at least two directions while the aluminum alloy material subjected to solution treatment is maintained under temperature conditions that do not cause softening of the aluminum alloy material by over-aging.
