Solid-solution ageing technology for ultrahigh-strength 7-series aluminum alloy material for heavy-haul train traction rod

The invention provides a solid-solution ageing technology for an ultrahigh-strength 7xxx-series aluminum alloy material. The solid-solution ageing technology comprises the following steps: firstly, extruding an aluminum alloy casting ingot to prepare an extruded material; then carrying out solid-solution quenching on the extruded material obtained by the previous step and then placing; after carrying out manual ageing, obtaining the 7xxx-series aluminum alloy material. According to the solid-solution ageing technology provided by the invention, a specific solid-solution system is used for thealuminum alloy extruded material; the solid-solution quenching is firstly carried out; then the step of placing is carried out and the manual ageing is carried out; especially, after the solid-solution quenching is carried out on an aluminum alloy and the placing treatment is carried out so that the mechanical strength and rigidity of the alloy are improved; after the aluminum alloy material is subjected to the solid-solution quenching, a large part of compound phase is dissolved into an alloy matrix; then the specific manual ageing step is combined so that the strength of the aluminum alloy is remarkably improved. A preparation technology is simple and a production speed completely meets a normal production speed; the solid-solution ageing technology is low in cost and suitable for beingpopularized and applied in industrial large-scale production, and has important practical significance.

Micro-foamed multiphase fiber-reinforced polypropylene composite material and preparation method thereof

The invention relates to a high-degradability micro-foamed multiphase fiber-reinforced polypropylene composite material which is composed of the following raw materials in percentage by weight: 30-70% of propylene copolymer, 2-8% of graft compatilizer, 5-15% of lignin, 3-20% of natural bamboo fiber, 5-20% of glass fiber chopped felt and 2-10% of elastomer toughener. The micro-foamed multiphase fiber-reinforced polypropylene composite material obtained according to the technical scheme has the advantages of low density, favorable foaming property, favorable mechanical properties, high degradability and the like. The lignin and natural fibrilia endow the reinforced polypropylene composite material with degradability. After the micro-foaming technique treatment, the composite material has lower density and higher degradability. Compared with the common talcum powder filled polypropylene composite material, on the premise of equivalent mechanical properties, the density of the reinforced polypropylene composite material is lowered by 15-25%, and the degradability can be obviously improved. The degradation rate of higher than 50% can be implemented by a simple landfilling-biodegradation process. The composite material has excellent characteristics of greenness and environment friendliness.
