Composite materials made of silicon carbide - fibers reinforced titanium alloy improved tensile strength

摘要

it is a process to change the crystal form of an alloy is disclosed. this change in the crystal form to do, the concentrations of the more volatile components of the alloy decreases and the concentration of the less volatile components is relatively increased. the method in the manufacture of reinforced structure can be carried out.to this end, an improved reinforced matrix and a procedure for its manufacture is taught. the reinforcement can be siliziumkarbidfu00e4den or other reinforcing threads. the matrix is a titanium 1421 alloy, the nominally 14 wt.% aluminum and 21 wt.% niobium contains.the matrix is formed by plasmaspritzen of powder from the alloy to the legierungsteilchen during this transition zone no homogeneous solid solution to overheat, while that by the plasma. as a result of the u00fcberhitzens changes the composition of the alloy under reducing aluminiumkonzentration and relatively increase the niobium and titankonzentrationen.as a result of the zusammensetzungsu00e4nderung is the form of method matrix changed under increase in the amount of beta phase crystal form of the alloy, and a fall in the amount of alpha 2 - crystal form of the alloy. the result is the formation of a matrix, the less breakage and riu00dfempfindlich and greater strength.
