Provided is a heat-resistant alloy having properties such as proof strength and hardness that allow substances with higher melting points than before to be joined. This heat-resistant alloy consists primarily of a first phase containing a molybdenum or tungsten metal phase and also has a second phase containing a Mo-Si-B alloy and a third phase containing titanium carbonitride, with the remainder consisting of unavoidable compounds and unavoidable impurities. La présente invention concerne un alliage thermorésistant ayant des propriétés telles que la limite d'élasticité et la dureté qui permettent que des substances ayant des points de fusion plus élevés qu'auparavant soient assemblées. Cet alliage thermorésistant est principalement constitué d'une première phase contenant une phase métallique de molybdène ou de tungstène et a également une deuxième phase contenant un alliage Mo-Si-B et une troisième phase contenant du carbonitrure de titane, le reste étant constitué de composés inévitables et d'impuretés inévitables.
