Summary:This invention relates to a technique that raises strength of metal and alloy, especially provides a method that in the precondition that chemical composition of metal and alloy is not changed, raising strength of metal and alloy by technique of dynamic state plastic deformation. Utilize technique of dynamic state high speed deformation, progress many manipulations with low temperature single direction, deformed strain rate is: 101-104s-1;Deformed strain variable is: total deflection exceed 1(computing method is:epsilon=ln H0/H>1),epsilon is deflection, H0 is thickness of material without deformation, H is thickness of material with deformation; Deformation temperature is: 30deg.C to -200deg.C. This invention utilizes technique of high speed deformation, preparative method is simple, and it is easy to control parameter of deformation technology and deformation temperature. It can produce metal and alloy with high intensity through necessarily improve orthodox deformation technique, optimize technology paramet
