Abstract

The invention discloses a shock-resistant corrosion-resistant aluminum alloy softball bat material and a preparing method thereof, and relates to the technical field of aluminum alloys. The shock-resistant corrosion-resistant aluminum alloy softball bat material comprises, by weight percentage, 0.3%-0.5% of Si, 0.8%-1.1% of Mg, 0.1%-0.3% of Mn, 0.3%-0.5% of Cu, 0.4%-0.7% of Fe, 3.5%-3.9% of Zn, 0.1%-0.3% of Li, 0.1%-0.3% of Cr, 0.3%-0.5% of Ti, 0.1%-0.3% of Ce, 0.05%-0.1% of Sc and the balance Al. All elements and contents in the alloy are reasonably optimized, the good mechanical property anddecay resistance are achieved, melt is subject to vibration scattering under a certain frequency in the preparing process, grains can be effectively refined, refining and homogenization of material organization and a second phase are facilitated, a casting ingot is subject to homogenization treatment through three-stage continuous temperature rise, the homogenization degree is more high, the mechanical property of the alloy can be further improved, the material organization is improved, the alloy material obtained after heat treatment has the good strength, hardness and corrosion resistance,the material is used for a softball bat, acute impact of balls to a bat body can be borne for a long period, cracking deformation is not prone to occurrence, and the service life is long.

Description

Technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to an impact-resistant and corrosion-resistant aluminum alloy softball stick material and a preparation method thereof. Background technique [0002] Softball is a kind of collective and antagonistic ball sport with baseball as its main feature. Common softball bats include wooden bats, aluminum bats, and composite bats. Among them, aluminum softball bats are generally of hollow structure. Compared with wooden baseball bats, their weight is lighter and their balance point is also ideal. Therefore, the batting performance is better, and at the same time, the aluminum softball bat is more durable, so this bat accounts for more than 70% of the market share. [0003] When the existing softball bats made of aluminum alloy are subjected to the impact force of the ball on the rod body, they cannot quickly return to their original shape under the severe impact of the ball, and often britt...

AI Technical Summary

Problems solved by technology

[0003] When the existing softball bat made of aluminum alloy is subjected to the impact force of the ball on the bat body, it cannot quickly return to its original shape under the violent impact of the ball, and often occurs brittle cracks, etc., and cracks or deformation will occur after long-term use; in addition, aluminum The corrosion resistance of the alloy is not high, which will also affect the service life of the bat. Although people often use coating methods to increase the corrosion resistance of aluminum alloys, the adhesion between the film layer and the aluminum alloy material is not high and it is easy to fall off. It is necessary to increase its corrosion resistance from the aluminum alloy itself
