Abstract
The invention discloses a housing of a gas turbine. The housing of the gas turbine comprises a metal body which is prepared from an alloy material; the alloy material is prepared from the following components in percentage by weight: 2.66% of Cr, 1.43% of Ce, 3.44% of Co, 1.57% of Mn, 0.62% of Sn, and the balance of Mg and inevitable impurities; the alloy material is prepared by the steps of 1) preheating Mg, Mg-Cr alloy, Mg-Ce alloy, Mg-Co alloy, Mg-Mn alloy and Mg-Sn alloy for 47min under a temperature of 195 DEG C; 2) charging protective gas into a smelting furnace, feeding preheated Mg, and then heating to smelt Mg; 3) feeding preheated Mg-Cr alloy, Mg-Ce alloy, Mg-Co alloy, Mg-Mn alloy and Mg-Sn alloy, and heating to fully smelt; 4) standing the melt and cooling to reach the temperature of 529 DEG C, and casting to obtain the alloy material. The housing of the gas turbine is outstanding in resistance to friction, high temperature, corrosion and weather, and high in strength.
