Abstract: The present invention provides an ?-type titanium alloy, the fracture toughness and thermal creep resistance of the prepared ?-type titanium alloy are improved by controlling the content of Al, Zr, and Sn. The room temperature strength is improved by adding a certain amount of Si, and the thermal creep resistance is further improved. The addition of a certain amount of C and Cr improves the high-temperature tensile properties of the prepared ?-type titanium alloy. The method provided by the invention has a simple process and low cost and can achieve good matching of low cost, high performance, and less processing capacity. The prepared ?-type titanium alloy in example 1˜4 of the invention has an elastic modulus of 124˜132 GPa, a tensile strength of 867˜881 MPa, a yield strength of 743˜762 MPa, an elongation of 22%˜24.0%, and a section shrinkage of 47%˜51% at 600° C.

Abstract: A method for spraying Robinia pseudoacacia on exposed shale wall to efficiently and rapidly restore green and improve soil pH value is provided. External-soil spray seeding is used to spray mixed microorganisms, organic fertilizer, and soil on exposed shale walls with a green plant of Robinia pseudoacacia to efficiently and rapidly restore green and improve soil pH value. The mixed microorganisms include Kocuria sp. X-22, Microbacterium sp. X-26, Bacillus sp. X-28 and Microbacterium sp. X-18, and the mixed microorganisms are added to organic fertilizer and soil by fermentation broth. The weight ratio of mixed microorganisms, organic fertilizer and soil is 1:1:8. The method can promote the rapid growth of Robinia pseudoacacia on the exposed shale wall and significantly increase organic matter content, effective phosphorus content, and pH value of the Robinia pseudoacacia soil.
