Abstract

The invention provides a pure metal material with both high strength and high plasticity and a preparation method thereof. The pure metal material is characterized in that crystal grains of microscopic structures of the pure metal material are composed of crystal grains with two different grain size ranges, and that is, the common micro crystal grains and the nano crystal grains; and the grain size range of the nano crystal grains is 10-200 manometers, and the grain size range of the micro crystal grains is 0.5-5 micrometers. The volume fraction of the nano crystal grains is 70% or above, and the volume fraction of the micro crystal grains is 30% or less. The micro crystal grains are inlaid in the nano crystal grains. The pure metal material is prepared through pulse electrolysis, room-temperature asymmetrical rolling, recrystallization and other methods.

Description

technical field [0001] The invention relates to a preparation method of a metal material, in particular to a pure metal material with both high strength and high plasticity and a preparation method thereof. Background technique [0002] Strength (commonly characterized by tensile strength, yield strength, etc.) and plasticity (commonly characterized by elongation, reduction of area, etc.) are two important mechanical properties of metal materials. High strength allows the metal to bear a large load before plastic deformation occurs, while large plasticity allows it to undergo large plastic deformation before failure, avoiding sudden brittle fracture. As engineering materials, people usually expect high-strength materials. However, when obtaining high-strength materials, the plasticity of the material will generally be lost; while improving the plasticity, the strength of the material will be lost. The two are a pair of contradictions, and generally cannot have both. [000...
