<p>There is provided a muffler made of a titanium alloy, wherein advantages of lightness and corrosion-resistance that the titanium alloy originally has, are used, and heat-resistance and oxidization-resistance are heightened without damaging costs or workability so that the span of life and flexibility for design are improved, particularly a muffler made of a titanium alloy, wherein the titanium alloy comprises 0.5-2.3 % by mass of Al and optionally one or more other alloying elements. The metal texture may comprise more than 90 % by volume of the alpha phase and 20 % or less of the beta phase. This muffler is superior in heat-resistance, oxidization-resistance, weldability and so on.</p> |
